Description

Technical Field

[0001] The present application relates to the field of satellite intelligent application technology, and specifically to an intelligent operation and control method and system based on an on-orbit satellite. Background Art

[0002] With the rise of commercial spaceflight, the number of satellites in orbit is increasing. After a satellite is launched into orbit, its status and movement are controlled by the ground-based measurement and control system. The satellite's measurement and control system is generally composed of 1 to 2 measurement and control centers and multiple ground equipment stations. The ground station is responsible for satellite communication and orbit parameter measurement, while the measurement and control center is responsible for satellite mission planning, telemetry information demodulation, remote control information compilation, satellite health assessment, and orbit determination and improvement.

[0003] The functions that the satellite's measurement, operation and control system needs to achieve are as follows: Tracking, telemetry detection: When performing measurement, operation and control management on a satellite, the ground station antenna is required to be able to follow the movement of the spacecraft and continuously and accurately point to the satellite. This process is called satellite tracking. When the satellite enters the station, real-time telemetry information from the satellite will be received in real time. The monitoring personnel need to detect the status of the satellite in real time and compare the important variables of the telemetry information. Once abnormal information is found, the emergency plan needs to be activated to repair the satellite in orbit. Remote control function: The ground can send remote control command information to command the satellite platform or payload to perform a certain action or task, such as adjusting attitude, igniting thrusters, unfolding sails, starting momentum wheels, carrying out data transmission or remote sensing tasks, etc.

[0004] Traditional satellite measurement, operation and control requires staff to be on duty at computers to perform real-time telemetry, detection and analysis based on the different orbit times of satellite transits. In addition, the instructions uploaded manually often cause problems such as forgotten or incomplete instructions due to fatigue at night or slow operation. As the number of satellites continues to increase, the number of satellites maintained by a single person will only increase. When the limit is reached, more people and more machines will be added to the daily operation and maintenance.

[0005] Based on this, a new technical solution is needed. Summary of the invention

[0043] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0044] The applicant has conducted in-depth research and improved exploration on satellite measurement, operation and control and found that:

[0045] With the rise of commercial aerospace, the number of satellites in orbit is increasing. SpaceX's "Starlink Project" has ushered in a new revolution in communications, with a total of "42,000 satellites". As of September 6, 2024, a total of 7,000 "Starlink" satellites have been launched. At present, China has 687 satellites in orbit, and constellation satellites such as "Jilin-1", "Zhuhai-1", "Gaojing-1", "Maritime Silk Road" and "Space Nebula" are continuously launched.

[0046] After a satellite is launched into orbit, its status and movement are controlled by the ground measurement and control system. The satellite measurement and control system is generally composed of 1 to 2 measurement and control centers and multiple ground equipment stations. The ground station is responsible for communication with the satellite and orbit parameter measurement, while the measurement and control center is responsible for satellite mission planning, telemetry information demodulation, remote control information compilation, satellite health assessment, and orbit determination and improvement.

[0047] Usually, for low-orbit satellites (non-polar orbit satellites) at an altitude of about 500km, each ground station can perform at least four orbits a day, including two orbits of orbit raising and two orbits of orbit lowering. The measurement and control time for each orbit is about 9 minutes (the ground station pitch is >5°), and the interval time between two consecutive orbits is about 90 minutes.

[0048] The functions that the satellite's measurement, operation and control system needs to achieve are as follows: Tracking, telemetry detection: When performing measurement, operation and control management on a satellite, the ground station antenna is required to be able to follow the movement of the spacecraft and continuously and accurately point to the satellite. This process is called satellite tracking. When the satellite enters the station, real-time telemetry information from the satellite will be received in real time. The monitoring personnel need to detect the status of the satellite in real time and compare the important variables of the telemetry information. Once abnormal information is found, the emergency plan needs to be activated to repair the satellite in orbit. Remote control function: The ground can send remote control command information to command the satellite platform or payload to perform a certain action or task, such as adjusting attitude, igniting thrusters, unfolding sails, starting momentum wheels, carrying out data transmission or remote sensing tasks, etc.

[0049] In order to ensure the accuracy, safety and reliability of remote control commands, the bit error rate of the remote control channel is generally required to be greater than 10-6 (the bit error rate of the telemetry channel is generally required to be greater than 10-5); in addition, after executing a remote control command, it is usually required to judge the execution status of the command through subsequent telemetry information. Only after the previous command is executed correctly, the next remote control command is allowed to be executed.

[0050] Traditional satellite measurement, operation and control, based on the different orbit times of satellite transits, have to arrange on-duty personnel to be on duty at the computer. Real-time telemetry detection and analysis, due to the conflict of holidays and vacations, also caused complaints from on-duty personnel; and the instructions uploaded by manpower, often caused problems such as forgetting to send instructions or incomplete sending due to fatigue or slow operation of personnel at night. With the continuous increase in the number of satellites, the state of relying solely on on-duty maintenance by personnel will only increase the number of satellites maintained by one person. When the limit is reached, more people and more machines will have to be added to the daily operation and maintenance.

[0051] In order to cope with the continuously increasing number of satellites in orbit, the new intelligent satellite operation and control will solve these problems in an all-round way and completely liberate manpower and material resources. Through intelligent telemetry monitoring, automated programs will replace personnel, and telemetry information will be automatically checked in real time and comprehensively. Through the intelligent remote control system, automatic injection and automatic identification of commands can be achieved. Through the intelligent alarm platform, satellite status information can be pushed to users in real time to understand the status of the satellite.

[0052] Based on this, the technical solutions provided by the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0053] The embodiment of this specification proposes a method for intelligent operation and control of an on-orbit satellite, such as Figure 1 As shown, the following steps are included: Step S1: Detect telemetry information of transit circles and analyze the telemetry information. Among them, the telemetry information of transit circles is intelligently detected, the telemetry information is comprehensively detected and judged, and the rules are fully automated to match; so as to realize intelligent detection of telemetry information.

[0054] Step S2: Send the remote control command to the satellite at the corresponding transit circle according to the analyzed telemetry information. In this process, the remote control command is sent intelligently and automatically, and the task command is automatically placed in the corresponding circle according to the rule setting, and is automatically sent to the satellite at the corresponding transit circle to realize intelligent command sending.

[0055] In one embodiment, step S1 includes but is not limited to the following basic operation steps:

[0056] Step S11: The ground station sends the received telemetry information to the telemetry terminal. Specifically, the telemetry terminal and the ground station link are detected in real time: the telemetry detection terminal will establish a constant link with the automatically operated ground station to detect the arrival of data in real time. Since the time interval between satellite circles is very long, it can sometimes reach more than 12 hours. During this period, in order to prevent link abnormalities, such as network interruption, time timeout link, software restart, etc., it is necessary to automatically check the network link in real time, and intelligently handle abnormal information to ensure the smooth flow of the link. When the satellite passes, the ground receiving station will directly send the received on-board information to the telemetry detection terminal. The telemetry terminal will detect the satellite entry signal as soon as possible, not only start to parse the data, but also send the entry signal to the intelligent remote control system. Among them, the Bat script monitors the running status of each software to ensure that the running status of each software is normal. The network link between the telemetry analysis software and the ground receiving station adopts udp (User Datagram Protocol, User Datagram Protocol) link, monitors the link status in real time, and when the link is detected to be interrupted, the reconnection mechanism is implemented within 1s to ensure the smooth flow of the link between the telemetry software and the ground station through udp reconnection.

[0057] Step S12: The telemetry terminal performs detection template matching in real time according to the received telemetry information and analyzes the telemetry information; wherein different detection templates correspond to different telemetry information.

[0058] Specifically, telemetry information analysis and real-time matching of preset alarm templates are carried out: the telemetry terminal will analyze the received on-board information in real time, and for different satellites, thousands of specific information can be analyzed, and each information has different expressions, such as numbers, letters, interval expressions, etc. In order to achieve automatic and intelligent judgment, users can set different detection templates to different scenes, which not only meets the needs of focusing on the detection of telemetry information, but also can be comprehensively related and interpreted. The telemetry terminal will analyze the telemetry information in real time based on the information of the template, match the template according to the alarm rules, and perform template matching in real time to achieve the effect of fully automated execution. Among them, the telemetry alarm matching rules are mainly divided into 7 modes: 1. The telemetry value is within the interval range; 2. The telemetry value is within the enumerated value; 3. The telemetry value is greater than or less than a fixed value; 4. The change interval of the telemetry value is associated with other telemetry a, and the value of a affects the change interval of the telemetry value; 5. The telemetry value is within the multi-task interval; 6. Special types, only alarm once; 7. Multiple alarm rules are superimposed, such as greater than a certain value, interval, and associated telemetry comparison.

[0059] Step S13: If the telemetry information does not match the threshold set by the detection template, the real-time alarm information is sent to the intelligent alarm platform. If the telemetry information matches the threshold set by the detection template, the normal working status message of the satellite is sent to the intelligent alarm platform when the satellite leaves the territory.

[0060] Specifically, the alarm information is pushed to the alarm module in real time: during the real-time analysis and real-time identification process, once the telemetry terminal finds that the telemetry information does not match the threshold set by the user template, the real-time alarm information will be sent to the intelligent alarm platform. During the entire process of sending telemetry information, if all tests meet the requirements, while waiting for the satellite to leave the country, the normal working status of the satellite will be sent to the intelligent alarm platform as a notification alarm message. Since the alarm platform can manage multiple satellites, multiple users, and multiple platforms at the same time, and different information of the same satellite is also related by people in different positions, when organizing the alarm information, the alarm information will be sent according to the predetermined information, such as satellite code + user group + alarm information.

[0061] The satellite in orbit arrives at the designated ground station at the scheduled time according to the orbit time recorded on the ground, and starts to send telemetry information; the ground station will send the telemetry information received from the designated satellite to the telemetry analysis terminal for back-end monitoring. Due to the complexity and large amount of analysis content, manual inspection cannot quickly find problems in a short time. This application can realize automatic real-time analysis, replace the original on-duty personnel operation, and realize unmanned operation.

[0062] In one embodiment, in step S11, the telemetry terminal is linked to the ground station, automatically checks the link in real time, and intelligently processes abnormal information to ensure smooth operation of the link.

[0063] In one embodiment, step S2 includes but is not limited to the following basic operation steps:

[0064] Step S21: Receive entry information in real time. Specifically, receive telemetry entry information in real time: the intelligent remote control terminal, as an independent module, will detect the entry message sent by the intelligent telemetry module in real time. After receiving the entry message, a preliminary check will be performed before sending the command, such as satellite status, data gate switch status, etc. At the same time, because the link between the ground station and the intelligent telemetry terminal may be unstable, multiple entry messages may be received within the entry circle, and the intelligent remote control terminal needs to handle such abnormal information. For example, if multiple messages are received for entry, the entry time is compared, and only the first entry time is taken within 10 minutes, and so on. The entry time of a single telemetry circle is generally not more than 10 minutes; the remote control terminal receives the entry message and obtains the telemetry status before preparing to send the command, such as satellite status and data gate switch status.

[0065] Step S22: After receiving the entry information, query and analyze the circle information in real time. Specific real-time query and analysis of circle information: The operation and control management of the entire satellite will be carried out according to the circle number corresponding to the circle, and the circle number is used as the identification of ground operation and control. The satellite is in orbit and does not send circle information. The only connection between the two is the time on the satellite. The ground will arrange the entire operation and control plan in advance according to the time on the satellite and save it in the specified list. After receiving the entry information and status detection, the intelligent remote control terminal must first find the corresponding circle information based on the time on the satellite.

[0066] Step S23: Real-time query of pending instruction tasks of lap information. Specific real-time query of pending instruction tasks of laps: After obtaining the laps, the intelligent remote control terminal will obtain the corresponding instruction task list. Different task instructions have different sending requirements, and the related instructions also have different status detections. The intelligent task instruction arrangement needs to be filled in according to different requirements; at the same time, it is necessary to make a plan for the failure of instruction injection, and different instruction plans are also different, such as re-injection, task rollback, etc.

[0067] Step S24: Send intelligent instructions according to the pending instruction task. Specific intelligent instruction sending: According to the instruction list in good condition, ground control needs to send them one by one to ensure the safety of the entire satellite. After the intelligent remote control terminal sends a command each time, it will compare the CRC (Cyclic Redundancy Check) on the satellite and the CRC of the instruction itself to see if they are consistent. If they are consistent, it means that the sending is successful. If they are inconsistent, the following abnormal operation will be performed.

[0068] When the satellite enters at the designated circle time, it is necessary not only to detect the satellite status information first, but also to check the task list and time sequence that need to be sent. After everything is ready, for each instruction to be injected, it is necessary to pay attention to the satellite status in real time and judge the injection operation preparation. The whole process is very labor-intensive and material-intensive, and it is also easy to make mistakes. The intelligent remote control terminal will automatically realize all these needs and achieve intelligent instruction sending.

[0069] In one embodiment, in step S21, after receiving the incoming message, the remote control terminal performs a satellite status check; in step S22, the remote control terminal searches for corresponding circle information in the scheduling list based on when on the satellite; in step S23, the remote control terminal obtains the corresponding instruction task list; wherein, the intelligent instruction scheduling performs instruction loading based on different requirements; in step S24, the remote control terminal sends instructions in sequence based on the instruction task list.

[0070] In one embodiment, in step S24, each time a command is sent, a comparison is made between the cyclic redundancy check code on the satellite and the cyclic redundancy check code of the command itself to determine whether the command is sent successfully; if the cyclic redundancy check codes are inconsistent, the command fails to be sent; the remote control terminal continuously detects and compares the cyclic redundancy check code within a preset time, and if the cyclic redundancy check code is not received within the preset time, the exception handling mechanism is activated.

[0071] In one embodiment, in step S24, before preparing to send the command, check whether the satellite status meets the conditions for sending the command. If the satellite status does not meet the conditions for sending the command, continue waiting and check the telemetry information in real time, and send a notification of the abnormal condition through the intelligent alarm platform until the conditions for sending the command are met.

[0072] Specific handling of intelligent command sending exceptions: Satellite-to-ground link communication cannot guarantee real-time stability and reliability, and ground communication cannot ensure stability in real time. Consideration of intelligent command exceptions will become very important. Exception 1: Before preparing to send a command, the satellite status will be checked first. Once the conditions are not met, the telemetry information will continue to wait and be checked in real time, and the specific abnormal conditions will be notified to relevant personnel or equipment through the message alarm platform until the sending conditions are met. Exception 2: Failed to send the command, and the CRC comparison is inconsistent. Due to the possible message delay in the satellite-to-ground link, and the repeated injection of the same command must be avoided, the intelligent remote control terminal will continue to detect and compare the CRC within 2 minutes. Once it has not been received within the time limit, the exception handling mechanism will be activated to resend, or the task will be rolled back.

[0073] In one embodiment, the operation and control method further includes step S3: automatically pushing the real-time information of satellite operation and control to view the satellite status in real time. Specifically, the alarm platform pushes: the intelligent message alarm platform automatically pushes the real-time information of satellite operation and control to WeChat, DingTalk, enterprise WeChat platform, etc., so that the satellite status can be viewed in real time.

[0074] In one embodiment, step S3 includes but is not limited to the following basic operation steps:

[0075] Step S31: Real-time detection of alarm information. Specifically, real-time monitoring of alarm information is performed: the alarm message platform supports the business needs of detecting multiple satellites and multiple platforms at the same time. Different satellite terminals and device terminals send the messages to be pushed to a unified message queue, and the intelligent alarm platform reads the alarm information in real time.

[0076] Step S32: Analyze and classify the alarm information in real time according to the message agreement. Specifically, perform real-time intelligent analysis: Analyze the message content in real time according to the message agreement of the intelligent platform to obtain the source of the message, the object of the message, the message content, the alarm status of the message and the corresponding application platform to which it is sent.

[0077] Step S33: Get the application object for sending the parsed and classified message, encapsulate the message format of the corresponding platform, and call the corresponding platform to send the parsed and classified message. Specific real-time information sending: Due to different usage habits of customers, the intelligent alarm platform will support different message application platforms, such as WeChat, DingTalk, enterprise WeChat, SMS, etc. Based on the analysis of the intelligent message in the previous step, the alarm platform first obtains the application object for sending the message, then encapsulates the message format of the corresponding platform, and finally calls the corresponding platform API (Application Programming Interface) to successfully send the message.

[0078] As the intermediate bridge between the intelligent operation and control system and the users, the alarm platform is particularly important for its system stability and the diversity of message support. Based on the alarm information generated in the first and second steps above, the alarm platform pushes the information to different groups and responsible persons in real time according to the classification and importance of the alarm information and the different recipients, thus realizing the real-time push of intelligent alarm information.

[0079] The embodiments of this specification also disclose an intelligent operation and control system based on an on-orbit satellite, and the intelligent operation and control method based on an on-orbit satellite using any of the above embodiments includes the following modules: a telemetry module: detecting telemetry information of transit circles and parsing the telemetry information. A remote control module: sending remote control instructions to the satellite at the corresponding transit circle according to the parsed telemetry information.

[0080] In order to cope with the continuously increasing number of satellites in orbit, the intelligent satellite operation and control of the present application comprehensively solves the problems that traditional on-orbit satellite operation and control relies on the accumulation of manpower and material resources, has slow timeliness and response, wastes a lot of manpower and material resources, and is extremely prone to errors, and completely liberates manpower and material resources. The present application uses intelligent telemetry monitoring, replaces personnel with automated programs, and automatically checks telemetry information in real time and comprehensively. Through the intelligent remote control system, it realizes automatic injection and automatic identification of commands, and pushes satellite status information to users in real time through the intelligent alarm platform to grasp the status of the satellite.

[0081] The present application relates to the design of an intelligent operation and control platform based on on-orbit satellites, which belongs to the field of satellite intelligent control technology. The introduction of satellite intelligent operation and control can completely liberate the costs of manpower and material resources, realize the intelligent and automated operation and control of on-orbit satellites, reduce the demand for manpower and material resources for operation and control, and at the same time avoid the probability of repeated human operations and errors, thereby improving the efficiency of operation and control.

[0082] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0083] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
