[0046] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0047] The terms used in one or more embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit one or more embodiments of the present application. The singular forms of "a", "said" and "the" used in one or more embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to any or all possible combinations of one or more associated listed items.

[0048] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0049] First, the terms involved in one or more embodiments of the present application are explained.

[0050] Satellite: An artificial satellite, a device that is launched into space by space flight vehicles such as rockets and space shuttles and orbits the earth or other planets like a natural satellite.

[0051] Dual-star positioning principle: Use the triangular relationship between two satellites operating in geosynchronous orbit and the user to determine the user's position on the earth's surface.

[0052] With the rapid development of satellite communication services, the threat of intentional and unintentional radio frequency interference on the ground to satellite communication is also increasing, and the number of these interference events is increasing. Therefore, how to accurately and quickly locate the interference source is of great significance.

[0053] The current satellite interference source positioning system is mainly based on the positioning system with the time and frequency difference measurement of two or three satellites in geosynchronous orbit as its technical basis.

[0054] The principle of dual-satellite positioning is that the main lobe and side lobe signals emitted by the transmitting station are forwarded by the transponders of the main satellite and the neighboring satellite respectively, and arrive at the receiving station. Due to the different lengths of the propagation paths, there is a relative time difference (DTO) in the received signals. If the positions of the satellite and the receiving station are known, the time difference between the satellite and the receiving station can be calculated and deducted. The space trajectory determined by the remaining DTO value is a hyperbolic surface, which can intersect with the earth's surface to form a curve. This curve is called the time difference position line (DTO-LOP). Due to the difference in the perturbation speed of the two satellites, different Doppler frequencies are caused on the two propagation paths of the uplink signal, namely DFO. Similar to DTO, the result of DFO measurement can also draw a position line on the earth, which is called the frequency difference position line (DFO-LOP). The intersection of the above two curves can get the position of the transmitting station.

[0055] The DTO and DTO parameters required for three-star positioning are obtained by correlating the cross ambiguity function (CAF) corresponding to the two binary star combinations of primary star neighbor 1 and primary star neighbor 2. The advantage of three-star time difference positioning is that it is not sensitive to frequency difference, so it can locate moving interference sources.

[0056] However, existing positioning systems have deficiencies and defects when performing positioning tasks, including:

[0057] 1) Since the interference occurs at an irregular time, it is a random event and may occur for a short time. The system user may have missed the signal occurrence time during the process from discovery to task establishment, and the system is not highly automated.

[0058] 2) Since different satellites have different beam types, and the frequency and polarization information of the radiation source signal are difficult to meet the positioning requirements for different positioning satellite combinations, the success rate of positioning using a selected template or configuration is not high;

[0059] 3) As traditional positioning software only stores and manages data from a single mission, it is not convenient to conduct comprehensive analysis and processing of multi-satellite forwarding and multiple reference data obtained from different missions, resulting in low data utilization.

[0060] The solution of the present application utilizes spectrum monitoring to detect interference sources in real time to achieve automatic guided positioning, triggers available resources to collect signals from multiple interference sources, and realizes a full collection mode; in terms of positioning data processing, near real-time data processing is achieved in a stream processing manner, and the positioning results are output; for interference signals that cannot be correctly located or require focused analysis, signal preprocessing, parameter estimation, multi-mode positioning and other processing are re-performed based on the fully collected data, thereby improving the positioning success rate and improving the efficiency of the positioning system.

[0061] In the present application, a satellite interference source positioning method is provided. The present application also relates to a satellite interference source positioning device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0062] See also Figure 1 , Figure 1 A schematic diagram of the system structure of a satellite interference source positioning method provided in an embodiment of the present application applied to a satellite interference source positioning system is shown.

[0063] Figure 1 Detailed description is given of a satellite interference source positioning system 100 used in the satellite interference source positioning method provided in an embodiment of the present application, wherein the satellite interference source positioning system 100 includes a processing device 102 and a service node 104.

[0064] In the satellite interference source positioning method in this embodiment, the service node 104 receives a satellite interference source positioning request, and determines the device resource information based on the interference source type set in the satellite interference source positioning request; thereby, the processing device 102 collects a satellite interference source information set based on the device resource information, and collects the satellite interference source information corresponding to the target satellite based on the device resource information; determines a target interference source positioning template according to the device resource information in the interference source positioning template set, and obtains the satellite interference source information collected by the processing device 102 based on the target interference source positioning template, wherein the processing device 102 in this embodiment includes antenna 1, antenna 2, antenna 3, a first-stage down converter, switch matrix 1, switch matrix 2, converter 1, converter 2, converter 3 and other sub-devices. In actual applications, sub-devices can also be added to the processing device 102 according to actual needs, such as adding antenna 4, converter 4, etc. This application does not limit the number of sub-devices included in the processing device; the service node 104 calculates the location information of the satellite interference source based on the satellite interference source information collected by the processing device 102.

[0065] The satellite interference source positioning method of the present application collects satellite interference source signals based on device resource information, thereby improving the richness of satellite interference source information; determines a target satellite interference source positioning template in a satellite interference source positioning template set, which is used to determine the position information of the satellite interference source, thereby improving the success rate and accuracy of interference source positioning.

[0066] Figure 2 A flowchart of a satellite interference source positioning method provided according to an embodiment of the present application is shown, which specifically includes the following steps:

[0067] Step 202: Receive a satellite interference source positioning request for a target satellite, wherein the satellite interference source positioning request includes a satellite interference source type set.

[0068] Among them, the satellite interference source positioning request refers to a request for determining the location information of the satellite interference source of the target satellite; the satellite interference source type set refers to a set composed of satellite interference source type information; the satellite interference source type information refers to the signal attribute information of the interference source signal of the satellite interference source, such as signal frequency information, signal bandwidth information, signal modulation method, etc.; in actual applications, the satellite interference source information can be composed of one or more signal attribute information, such as using the signal frequency information of satellite interference source A as satellite interference source type information, or using the signal frequency information and signal modulation method information of satellite interference source A as satellite interference source type information, etc.

[0069] Specifically, a service node of the satellite interference source positioning system receives a satellite interference source positioning request for a target satellite; wherein the satellite interference source positioning request may be a request generated by an interference source detection device included in the satellite interference source positioning system, or may be a request generated by an interference source detection device outside the satellite interference source positioning system; and the request includes a satellite interference source type set consisting of satellite interference source type information collected by the interference source detection device.

[0070] Before receiving a satellite interference source positioning request for a target satellite, a method for generating a satellite interference source positioning request may include:

[0071] Monitoring interference source signals in satellite spectrum data of the target satellite;

[0072] The satellite interference source type information corresponding to the interference source signal is obtained, and a satellite interference source positioning request is generated based on the satellite interference source type information.

[0073] Among them, the interference source signal refers to the signal of the satellite interference source corresponding to the target satellite; after monitoring the interference source signal, the signal attribute information of the interference source signal is further determined, and the signal attribute information is used as the satellite interference source type information to generate an interference source positioning request.

[0074] In a specific implementation of the present application, spectrum detection device A monitors satellite A satellite spectrum data; uses the interference detection method of the spectrum monitoring device to automatically monitor the interference source signal in the satellite spectrum data; determines the signal attribute information of the interference source signal, including: signal frequency information, signal bandwidth information, signal type information and signal modulation method information, and generates a satellite interference source positioning request based on the signal attribute information.

[0075] The interference source signals of the satellite are automatically monitored by spectrum detection, and a satellite interference source positioning request is generated, thereby realizing real-time monitoring of the interference source signals and automatic generation of satellite interference source requests.

[0076] Step 204: Determine device resource information based on the satellite interference source type set, and collect a satellite interference source information set based on the device resource information.

[0077] Among them, the equipment resource information refers to the resource information used by the satellite interference source positioning system in this positioning task. For example, the satellite interference source positioning system contains 5 antennas that can be used for positioning task processing, and only antenna 1, antenna 2 and antenna 3 are used in this positioning task. Then the information corresponding to antenna 1, antenna 2 and antenna 3 is the equipment resource information of this positioning task; the satellite interference source information set refers to the set composed of satellite interference source information collected by each information collection device.

[0078] Further, the method for determining device resource information based on the satellite interference source type set may include:

[0079] Obtaining initial device resource information of the service node;

[0080] Determine the neighboring satellite information corresponding to the target satellite based on the satellite interference source type set;

[0081] The device resource information is determined in the initial device resource information according to the neighboring satellite information.

[0082] Among them, the initial device resource information refers to the upper limit of resources that can be collected simultaneously by the collection device corresponding to the service node. For example, the satellite interference source positioning system includes 10 antennas, and each antenna collects information corresponding to one satellite at the same time, then the initial device resource information is 10; the neighboring satellite information refers to the information of each satellite corresponding to the target satellite. For example, the neighboring satellite information corresponding to the target satellite A is neighboring satellite 1 and neighboring satellite 2.

[0083] Specifically, determine the acquisition device corresponding to the service node, and obtain the initial device resource information corresponding to the acquisition device; determine the neighboring satellite that can be used as the target satellite among the available satellites according to the set of satellite interference source types, and obtain the neighboring satellite information; based on the neighboring satellite information, determine the device resource information used for this positioning task in the initial device resource information.

[0084] Furthermore, the number of satellites to be collected that can be used for the positioning task is determined based on the neighboring satellite information and the target satellite; the upper limit of the number of satellites that can be collected by the interference source positioning system is determined based on the initial device resource information; when the number of satellites to be collected is less than the upper limit of the number of satellites, the devices for the number of satellites to be collected can be randomly determined in the initial device resource information to form the device resource information; when the number of satellites to be collected is equal to the upper limit of the number of satellites, each device corresponding to the initial device resource information is used for data collection for this positioning task, that is, the device resource information is the initial device resource information at this time; when the number of satellites to be collected is greater than the upper limit of the number of satellites, the devices consistent with the upper limit of the number of satellites are randomly determined among the satellites to be collected for data collection for this positioning task, that is, the device resource information is the initial device resource information at this time.

[0085] After determining the device resource information, each collection device corresponding to the device resource information can collect the satellite interference source information of the target satellite respectively to generate a satellite interference source information set. For example, the primary satellite 1 and the neighboring satellites 2 and 3 corresponding to the primary satellite 1 are determined, and the satellite interference source information corresponding to the primary satellite 1 is collected by antenna 1 in the satellite interference source positioning system, the satellite interference source information corresponding to the neighboring satellite 2 is collected by antenna 2, and the satellite interference source information corresponding to the neighboring satellite 3 is collected by antenna 3.

[0086] The satellite interference source information is fully collected through the equipment resource information, avoiding the problem of being unable to collect due to the interference source signal being too short, and enriching the collected satellite interference source information, which is convenient for the subsequent determination of the interference source location information.

[0087] Step 206: Determine a target interference source location template in the interference source location template set, wherein the interference source location template set is determined based on the device resource information.

[0088] After obtaining the satellite interference source information set, it is necessary to further determine the satellite interference source positioning template for calculating the location information of the satellite interference source, so as to facilitate the subsequent calculation of the location information based on the satellite interference source positioning template and the satellite interference source information.

[0089] The interference source positioning template set refers to a set composed of interference source positioning templates, and the interference source positioning template is generated according to the target neighboring satellite information corresponding to the device resource information; the target neighboring satellite information is the neighboring satellite information corresponding to the device resource information and is used to generate the interference source positioning template.

[0090] Specifically, before determining the target interference source localization template in the interference source localization template set, the method for generating the interference source localization template set may include:

[0091] Determine at least one target neighboring satellite information corresponding to a preset positioning configuration type and the device resource information;

[0092] Generate an interference source positioning template corresponding to each target neighboring satellite information based on the preset positioning configuration type and each target neighboring satellite information;

[0093] An interference source positioning template set is generated according to each interference source positioning template.

[0094] Among them, the preset positioning configuration type refers to the configuration type that can perform positioning tasks, such as dual-star configuration and triple-star configuration; in actual applications, the preset positioning configuration type needs to be determined based on the neighboring satellite information corresponding to the target satellite. For example, if the neighboring satellite information is neighboring satellite 1, only the dual-star configuration type can be used. If the neighboring satellite information is neighboring satellite 1 and neighboring satellite 2, the triple-star configuration type can be used; the target neighboring satellite information refers to the information of the neighboring satellite that can perform this positioning task.

[0095] Different interference source positioning templates can be generated according to different preset positioning configuration types and different target neighboring satellite information; for example, it is determined that there are corresponding neighboring satellites 1 and 2 for primary satellite 1, and based on the preset positioning configuration type dual-satellite configuration, an interference source positioning template m corresponding to primary satellite 1 and neighboring satellite 1 can be generated, and an interference source positioning template n corresponding to primary satellite 1 and neighboring satellite 2 can also be generated.

[0096] Furthermore, an interference source positioning template can be generated based on the positioning configuration and positioning processing rules; wherein the positioning processing rules refer to the rules for calculating the location information of the satellite interference source, such as the frequency difference rule, the time difference rule, the frequency time difference rule, etc.; the positioning configuration refers to the configuration that can perform the positioning task.

[0097] For example, the positioning configurations corresponding to the binary star configuration type are configuration a and configuration b, configuration a is composed of primary star 1 and neighboring star 2, and configuration b is composed of primary star 1 and neighboring star 3; the positioning processing rules corresponding to the binary star configuration type are frequency difference rule, time difference rule and frequency time difference rule, then based on the combination of positioning configuration and positioning processing rules, 6 interference source positioning templates can be generated, namely “configuration a, frequency difference rule”, “configuration b, frequency difference rule”, “configuration a, time difference rule”, “configuration b, time difference rule”, “configuration a, frequency time difference rule”, and “configuration b, frequency time difference rule”.

[0098] For example, the positioning configuration corresponding to the three-star configuration type is configuration x, and the positioning processing rules corresponding to the three-star positioning principle are dual time difference rule and dual frequency difference rule. Based on the combination of positioning configuration and positioning processing rules, two interference source positioning templates can be generated, namely: "Configuration x, dual time difference rule" and "Configuration x, dual frequency difference rule".

[0099] After obtaining at least one interference source positioning template based on the positioning configuration and the positioning processing rule, each interference source positioning template constitutes an interference source positioning template set.

[0100] After generating the interference source positioning template set, the method for determining the target interference source positioning template in the interference source positioning template set includes:

[0101] Determine an interference source location template subset in the interference source location template set based on the device resource information;

[0102] Each interference source positioning template in the interference source positioning template subset is respectively used as a target interference source positioning template.

[0103] The interference source location template subset refers to a set of interference source location templates selected from the interference source location template set according to device resource information.

[0104] Specifically, according to the device resource information, the interference source location template corresponding to the device resource information can be determined in the interference source location template set to form an interference source location template subset, so as to subsequently calculate the location information of the interference source based on each interference source location template in the interference source location template subset; in addition, some interference source location templates can be selected from the interference source location template set based on actual needs, that is, the interference source location templates can be manually selected to form an interference source location template subset.

[0105] After determining the interference source positioning template subset, each interference source positioning template in the interference source positioning template subset is used as a target interference source positioning template, so that position information calculated according to each target interference source positioning template can be obtained later.

[0106] Step 208: acquiring target satellite interference source information from the satellite interference source information set based on the target interference source positioning template, and determining the position information of the satellite interference source corresponding to the target satellite according to the target satellite interference source information.

[0107] After determining the target interference source positioning template in the target interference source positioning template set, the target satellite interference source information corresponding to the target interference source positioning template is determined in the satellite interference source information set obtained through collection based on the target interference source positioning template, thereby calculating the position information of the satellite interference source based on the target satellite interference source information.

[0108] The target satellite interference source information refers to the satellite interference source information corresponding to the target interference source positioning template in the satellite interference source information set; the position information refers to the physical position information of the satellite interference source corresponding to the target satellite.

[0109] Specifically, the method for acquiring target satellite interference source information in the satellite interference source information set based on the target interference source positioning template may include:

[0110] Determine the target reference station and information collection equipment based on the target interference source positioning template;

[0111] The satellite interference source signal collected by the information collection device and the reference signal of the target reference station are obtained in the satellite interference source information set.

[0112] Among them, satellite interference source information refers to the signal attribute information of the satellite interference source within a preset time period; information collection equipment refers to the equipment used to collect information in the satellite interference source positioning system, such as antenna equipment; target reference station refers to the earth station that provides reference position information.

[0113] Specifically, parameter configuration information is included in the target interference source positioning template; the information collection device is configured based on the parameter configuration information, and the target reference station is determined; based on the configured information collection device, the satellite interference source information of the satellite interference source and the reference information of the target reference station are fully collected to obtain a satellite interference source information set; based on the target interference source positioning template, the target reference station and the information collection device are determined, and the reference signal collected by the target reference station and the reference signal collected by the information collection device are obtained in the satellite interference source information set as the target interference source satellite information.

[0114] After the target satellite interference source information is determined, the location information of the satellite interference source is determined based on the target satellite interference source information.

[0115] Specifically, the method for determining the position information of the satellite interference source corresponding to the target satellite according to the target satellite interference source information may include:

[0116] Determine the estimation result and the preset estimation result corresponding to the satellite interference source signal;

[0117] When the estimation result is greater than or equal to the preset estimation result, extracting the satellite interference source parameter corresponding to the satellite interference source signal and the reference parameter corresponding to the reference signal, wherein the preset estimation result is determined based on the satellite interference source type information;

[0118] The position information of the satellite interference source corresponding to the target satellite is calculated according to the satellite interference source parameter and the reference parameter.

[0119] Among them, the preset parameter result refers to the pre-set parameter result value; the parameter result refers to the result determined based on the satellite interference source type set for judging the data availability, for example, calculating the signal-to-noise ratio of the satellite interference source; the satellite interference source parameter refers to the parameter extracted from the satellite interference source information for calculating the position information; the reference parameter refers to the parameter extracted from the reference information for calculating the position information; the position information refers to the geographical location information of the satellite interference source, such as the latitude and longitude information of the satellite interference source.

[0120] In a specific embodiment of the present application, satellite interference source information of the satellite interference source corresponding to the satellite L collected by the collection device I and the reference information of the reference station H are obtained in the interference source information set as the target satellite interference source information; the estimation result corresponding to the target interference source information is calculated, and it is determined whether the estimation result is greater than or equal to the preset estimation result, specifically, the signal-to-noise ratio of the satellite interference source calculated according to the target satellite interference source information is 40dB, and the preset satellite interference source information threshold is determined to be a signal-to-noise ratio of 20dB, and then it is determined to perform subsequent calculations based on the satellite interference source information; further, the position information of the satellite interference source corresponding to the satellite L is calculated according to the interference source positioning template and the satellite interference source information and the reference information.

[0121] It should be noted that in actual applications, only some interference source positioning templates can be selected from the satellite interference source positioning template set as target interference source positioning templates. Therefore, when the target satellite interference source information corresponding to the selected target interference source positioning template does not meet the requirements, that is, the estimation results corresponding to each target satellite interference source information are less than the preset estimation results, interference source positioning templates other than the target interference source positioning template can also be selected from the satellite interference source positioning template for calculating the position information.

[0122] Specifically, a method for selecting an interference source positioning template other than a target interference source positioning template from a satellite interference source positioning template set and calculating the position information may include:

[0123] When the estimation result is less than the preset estimation result, a reference interference source positioning template is selected from the interference source positioning template set, wherein the reference interference source positioning template is a non-target interference source positioning template in the interference source positioning template set;

[0124] A reference satellite interference source signal is collected based on the reference interference source positioning template, and a step of determining the position information of the satellite interference source corresponding to the target satellite is performed according to the target satellite interference source information.

[0125] Among them, the reference positioning template refers to an interference source positioning template in an interference source positioning template set that is different from the target interference source positioning template; the reference satellite interference source information refers to the satellite interference source information obtained based on the reference positioning template.

[0126] Specifically, when the estimation result corresponding to each target satellite interference source information is less than the preset estimation result, an interference source positioning template different from the target interference source positioning template is selected in the interference source positioning template as the reference satellite interference source positioning template, and the specific selection can be based on actual needs; according to the reference satellite interference source positioning template, reference satellite interference source information is obtained in the satellite interference source information set, and it is further determined whether the estimation result corresponding to the reference satellite interference source information is greater than or equal to the preset estimation result; if so, further perform the step of determining the position information of the satellite interference source corresponding to the target satellite based on the reference satellite interference source information; if not, obtain other interference source positioning templates again in the interference source positioning template, or use other methods to locate the satellite interference source.

[0127] In practical applications, the satellite interference source information can be stored so that a comprehensive analysis of the satellite interference source can be achieved later.

[0128] Specifically, after determining the position information of the satellite interference source corresponding to the target satellite according to the target satellite interference source information, the method may further include:

[0129] The satellite interference source signal and the reference signal of the target satellite are stored in a database, wherein the database contains historical satellite interference source signals and historical reference signals.

[0130] Among them, the historical satellite interference source signal refers to the satellite interference source signal collected based on the historical satellite interference source positioning request; the historical reference signal refers to the reference signal collected at the reference station based on the historical satellite interference source positioning request.

[0131] The satellite interference source signal and the reference signal are stored in a database. When each interference source positioning template in the interference source positioning template set cannot obtain the satellite interference source information that meets the requirements, the position information of the satellite interference source corresponding to the target satellite can be calculated based on the historical satellite interference source information and historical reference information in the database.

[0132] Specifically, in the case where it is impossible to obtain satellite interference source information that meets the requirements, further positioning analysis can be performed based on the fully collected satellite interference source information stored in the database to determine the position information of the satellite interference source of the target satellite, thereby ensuring the comprehensiveness of the positioning analysis.

[0133] The satellite interference source positioning method provided in the present application receives a satellite interference source positioning request for a target satellite, wherein the satellite interference source positioning request includes a satellite interference source type set; determines device resource information based on the satellite interference source type set, and acquires a satellite interference source information set based on the device resource information; determines a target interference source positioning template in an interference source positioning template set, wherein the interference source positioning template set is determined based on the device resource information; acquires target satellite interference source information in the satellite interference source information set based on the target interference source positioning template, and determines the position information of the satellite interference source corresponding to the target satellite according to the target satellite interference source information.

[0134] An embodiment of the present application realizes the collection of satellite interference source signals based on device resource information, thereby improving the richness of satellite interference source information; determining a target satellite interference source positioning template in a set of satellite interference source positioning templates for determining the location information of the satellite interference source, thereby improving the success rate and accuracy of interference source positioning.

[0135] The following combination Figure 3 Taking the application of the satellite interference source positioning method provided by the present application in the satellite interference source positioning system Q as an example, the satellite interference source positioning method is further described. Figure 3 A processing flow chart of a satellite interference source positioning method applied to a satellite interference source positioning system Q provided in an embodiment of the present application is shown, which specifically includes the following steps:

[0136] Step 302: After the spectrum monitoring module detects the interference source signal targeting the target satellite, it sends an interference source positioning request to the integrated management and control template to complete the positioning trigger, wherein the interference source positioning request includes a guidance parameter.

[0137] Among them, the satellite interference source positioning system Q includes a spectrum monitoring module, a positioning application module, an integrated management and control module, a frequency converter matrix antenna equipment, an acquisition preprocessing module, and a positioning solution module.

[0138] Specifically, the spectrum monitoring module in the satellite interference source positioning system Q is used to monitor the satellite spectrum of the satellite in real time. The interference monitoring capability of the equipment is used to automatically detect interference signals, determine the signal frequency, bandwidth, signal type, modulation method and other information, and combine them into guidance parameters for interference source positioning, and initiate a positioning guidance task.

[0139] Step 304: The positioning application module sends a positioning trigger task based on the comprehensive management and control module, and selects a target interference source positioning template from the interference source positioning templates.

[0140] Specifically, the integrated management and control module receives the positioning guidance task, detects the current positioning system status, and sends the guidance task information to the positioning application; that is, the service node receives the satellite interference source positioning request for the target satellite, and sends the guidance task information to the positioning application module of the service node based on the satellite interference source positioning request.

[0141] Step 306: The integrated management and control module receives the target interference source positioning template determined by the positioning application module.

[0142] Specifically, the integrated control module searches for positioning task templates, i.e., the positioning templates of target interference sources, and formulates positioning tasks according to signal frequency bands, transponders, polarization modes, etc. Before searching for positioning task templates, it is also necessary to generate positioning task templates based on the neighboring satellite information corresponding to the device resource information of the service node.

[0143] Step 308: The frequency converter matrix and antenna equipment are configured according to the control parameters carried by the target interference source positioning template sent by the integrated management and control module.

[0144] Specifically, the integrated management and control module parses the antenna, frequency converter, matrix and other equipment parameters set in the target interference source positioning template, and completes the setting of link equipment such as antenna and frequency converter matrix.

[0145] Step 310: The integrated management and control module receives the collection results fed back by the inverter matrix antenna device.

[0146] Specifically, the integrated management and control module receives the collectible resource information fed back by the inverter matrix antenna device to determine the operation status of the collection device.

[0147] Step 312: The comprehensive management and control module sends the task parameters in the collection results to the collection preprocessing module to store the task parameters.

[0148] Step 314: The acquisition preprocessing module feeds back the stored file path to the comprehensive management and control module.

[0149] Specifically, after the link device is successfully set up, the available acquisition device resources are scheduled to collect the interference signal issued by the task and multiple available reference signals, store them on disk, complete the full collection of the interference source signal, and return the file path of the storage interference source signal to the comprehensive management and control module.

[0150] Step 316: The positioning solution module performs positioning calculation based on the path and parameters fed back by the comprehensive management and control module to obtain positioning results and parameter estimation results.

[0151] Step 318: The positioning solution module feeds back the positioning result and the estimation result to the comprehensive management and control module.

[0152] Specifically, the positioning solution module will determine whether the positioning result and the estimation result meet expectations; if so, continue to execute step 320, if not, return to execute step 308, that is, replace the new target interference source positioning template to execute the positioning task.

[0153] Specifically, the interference signal and reference signal parameters are extracted and positioned, and near real-time data processing is achieved in a stream processing manner to obtain positioning results. It is determined whether the task template needs to be replaced based on the evaluation results. If necessary, it returns to step 308, and the terminal reselects the task template and issues the positioning task, and re-executes the positioning processing flow. If not, the target interference source positioning template is determined to output subsequent positioning results.

[0154] Step 320: The positioning application module displays the positioning results and parameter estimation results that meet expectations.

[0155] Specifically, after the positioning task is completed, the expected positioning results are displayed; for interference signals that cannot be correctly located or require focused analysis, positioning analysis is performed based on the full collection data stored in the database.

[0156] Users can select data through the human-computer interaction interface, determine a certain positioning configuration and its reference station, observe the spectrum of the main satellite, the spectrum of the neighboring satellite and the signal status, and determine whether the target signal still exists and whether there is interference from the neighboring satellite; configure preprocessing parameters according to the target signal type and signal analysis results, and complete signal preprocessing through human-computer interaction; if the same-frequency signal cancellation is required, the signal cancellation can be completed more accurately through human-computer interaction; during positioning analysis, select the effective correlation peak on the mutual ambiguity diagram, accurately estimate the time-frequency difference parameters, and select the effective time difference estimation results for positioning solution; display the positioning results on the map, and use the error analysis tool to evaluate the positioning results. Any of the above nodes can be selected for automatic execution or human-computer interaction. If this positioning and reference station combination does not meet the positioning requirements after analysis, different neighboring satellites and different reference station combinations can be replaced based on the full acquisition data, and the positioning analysis can be re-performed.

[0157] The satellite interference source positioning method of the present application uses spectrum monitoring and automatic interference discovery functions to enable the positioning system to quickly position and respond to interference signals. After the interference signal appears, the preset positioning template can be used to position and process the interference, avoiding the cumbersome task formulation process; the positioning template is added to automatically judge the switching process, and different satellites and reference station combinations can be traversed and tried in the positioning task until a stable positioning effect is achieved, avoiding the problem of low positioning success rate using a selected template or configuration; the positioning analysis function based on the full acquisition mode is designed, and manual detailed analysis can be performed on interference signals that cannot be correctly located or require key analysis, and different neighboring satellites and reference station combinations can be replaced to re-perform positioning analysis, thereby improving the utilization rate of collected data.
