[0036] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0037] The embodiments of the present application can provide a satellite search method, device and storage medium. In practical applications, the satellite search method can be implemented by an electronic device, and each functional entity in the electronic device can be collaboratively implemented by hardware resources of a computer device (such as a terminal device, a network device, etc.), such as computing resources such as a processor, and communication resources (such as for supporting various communication methods such as optical cables and cellular).

[0038] Of course, the embodiments of the present application are not limited to being provided as methods and hardware, and there may be multiple implementation methods, such as being provided as a storage medium (storing instructions for executing the star search method provided in the embodiments of the present application).

[0039] The following describes various embodiments of the star search method, device, and storage medium provided in the embodiments of the present application.

[0040] The satellite search method provided in the embodiment of the present application is applied to a terminal device, and can be as follows: Figure 1 As shown, including:

[0041] S101. Determine the location information of the terminal device.

[0042] The terminal device may start the satellite search process based on a set event or when the satellite search switch is triggered, and after starting the satellite search process, determine the location information of the terminal device. The set event may include but is not limited to: receiving a command for satellite communication, receiving an emergency call command, etc.

[0043] In the embodiment of the present application, when the terminal device is passing through a satellite and the location information changes due to movement, the determined location information may include the location information after the location change.

[0044] In the embodiment of the present application, the terminal device may determine the location information of the terminal device in a manner including but not limited to based on GPS satellites, based on cellular networks, based on accessed wifi networks, etc. The location information obtained by the terminal device may include longitude and latitude information.

[0045] In the embodiment of the present application, before determining the location information of the terminal device, it can be determined whether the sensor of the terminal device used to obtain the location information has been calibrated. If the sensor has been calibrated, the location information can be directly obtained based on the calibrated sensor. If the sensor has not been calibrated, the sensor can be calibrated first, and the location information can be obtained based on the calibrated sensor.

[0046] S102: Search for first target satellite information in first information based on the location information, where the first information includes satellite information of a plurality of first satellites, and the first target satellite information is satellite information of the first target satellite.

[0047] After the terminal device determines the location information, it can search the stored first information for satellite information corresponding to the first location information in the first information. In the embodiment of the present application, the satellite searched from the first information is considered to be the first target satellite information, and the first target satellite information is the information of the first target satellite.

[0048] Here, the first information includes satellite information of a plurality of first satellites, wherein position information corresponding to different first satellites is the same or different.

[0049] If the location information of the terminal device corresponds to satellite information of a first satellite in the first information, the satellite information is determined to be the first target satellite information.

[0050] In one example, the first information includes satellite information of the following satellites: satellite A, satellite B, satellite C and satellite D, satellite A, satellite B, satellite C and satellite D correspond to different location information, and the satellite information of satellite D corresponds to the location information of the terminal device, then the satellite information of satellite D is determined to be the first target satellite information.

[0051] If the location information of the terminal device corresponds to satellite information of multiple first satellites in the first information, satellite information of one first satellite among the satellite information of the multiple first satellites is determined as the first target satellite information.

[0052] In one example, the first information includes satellite information of the following satellites: satellite A, satellite B, satellite C and satellite D. The satellite information of satellite C and the satellite information of satellite D correspond to the location information of the terminal device, then one of the satellite information of satellite D and the satellite information of satellite C is determined as the first target satellite information.

[0053] In the embodiment of the present application, when the first information includes satellite information of multiple first satellites corresponding to the location information of the terminal device, one location information may be randomly selected from the multiple location information in the location information as the first target information, or one satellite information may be selected from the satellite information of multiple first satellites in the location information as the first target satellite information based on a set selection rule. The set rule may include the number of satellite connections, signal strength, etc.

[0054] Regarding the satellite information of the first satellite in the first information, the satellite information may include the satellite identifier of the corresponding first satellite, satellite resources, and other information used to connect to the first satellite. In the embodiment of the present application, the content included in the satellite information is not limited.

[0055] The satellite information of a first satellite in the first information may be understood as a record, which is directly stored in the memory of the terminal device, or may be stored in the memory of the terminal device in the form of a list.

[0056] In an embodiment of the present application, the terminal device may receive the first information from the server, and a client connected to the server may be running in the terminal device, and the client may access the server and receive the first information from the server.

[0057] The server may receive satellite information of satellites connected to the satellite communication devices during satellite communication and location information during satellite communication from multiple satellite communication devices, and may organize the satellite information and location information received from the multiple satellite communication devices to obtain first information.

[0058] The first information may include satellite information corresponding to each location information in a plurality of location information, and may also include satellite information corresponding to each area in a plurality of areas, wherein different areas correspond to different location ranges, and different areas are determined based on the location information corresponding to the satellite information.

[0059] In one example, if Figure 2 As shown, after the terminal devices 201, 202, 203, and 204 establish a connection with the satellite and perform satellite communication, they can respectively send their own location information and satellite information of the connected satellite to the server 200, wherein the information sent by the terminal device 1 includes: location information A and satellite information A, the information sent by the terminal device 2 includes: location information B and satellite information B, the information sent by the terminal device 3 includes: location information C and satellite information C, and the information sent by the terminal device 4 includes: location information D and satellite information D, and the first information includes: satellite information A corresponding to the location information A, satellite information B corresponding to the location information B, satellite information C corresponding to the location information C, and satellite information D corresponding to the location information D. After the server 200 determines the first information, it can synchronize the first information to the terminal devices 201, 202, 203, 204, and 205, and the terminal device 205 stores the first information, and when it is necessary to search for satellites, it can determine its own location information and search for the first target satellite information from the first information based on its own location information.

[0060] In the embodiment of the present application, when there are multiple different satellite information with the same location information, the server will simultaneously correspond the multiple satellite information to the location information.

[0061] In the embodiment of the present application, when the location information of multiple satellite communication devices is close, that is, the distance is less than the set first distance, the location information of the multiple satellite communication devices can also be considered to be the same. In this case, one of the multiple location information or a common location information determined based on the multiple location information can represent the location information of the multiple satellite communication devices.

[0062] In the embodiment of the present application, the situation where the location information is the same but the satellite information is different can be understood as the intersection area of ​​the satellite coverage areas of multiple satellites, and different terminal devices can perform satellite communication with different satellites in this intersection area.

[0063] In the embodiment of the present application, when the first information in the server is updated, the server may synchronously update the first satellite in the terminal device.

[0064] S103: Establish a connection with the first target satellite based on the first target satellite information to perform satellite communication based on the first target satellite.

[0065] After the terminal device determines the first target satellite information, it establishes a connection with the first target satellite based on the first target satellite information. Here, the established connection is a satellite connection. After the terminal device establishes a connection with the first target satellite, satellite services such as sending and receiving satellite messages and satellite calls can be performed based on the first target satellite.

[0066] In the embodiment of the present application, the location information of the terminal device is determined; based on the location information, the first target satellite information is searched in the first information, the first information includes satellite information of multiple first satellites, and the first target satellite information is the satellite information of the first target satellite; based on the first target satellite information, a connection is established with the first target satellite to perform satellite communication based on the first target satellite. Thus, the first target satellite to establish a connection is determined based on the current location information of the terminal device, the satellite search speed is accelerated, and the efficiency of satellite communication is ensured.

[0067] In some embodiments, the first information includes satellite information of a first satellite corresponding to each of the multiple regions; S102 searches for first target satellite information in the first information based on the location information, such as Figure 3 As shown, including:

[0068] S1021, determining a target area where the location information is located among the multiple areas;

[0069] S1022. Determine second information corresponding to the target area in the first information;

[0070] S1023. Determine the first target satellite information based on the second information.

[0071] Here, the first information includes satellite information of the first satellite corresponding to each area in multiple areas, which determines the area to which the location information of the terminal device in the first information belongs as the target area, wherein different areas can be characterized based on different location information, location ranges, and area identifiers.

[0072] When different areas are represented based on different position information, the area can be understood as an area within a set second distance range centered on the position information.

[0073] Here, the terminal device can determine the location range determined by each location information in the first information and the second distance, and determine the location range to which the location information of the terminal device belongs. The terminal device can also determine an optional location range based on the location information and the second distance, and determine the area represented by the location information within the optional location range in the first information as the target area.

[0074] In one example, the location information of the terminal device is location information 1, and the first information includes: satellite information corresponding to each location information in location information A, location information B, location information C, and location information D. Location information A, location information B, location information C, and location information D are respectively based on the second distance to obtain location range A, location range B, location range C, and location range D. Among them, if location information 1 is located in location range D, then the area corresponding to location information D is determined to be the target area.

[0075] In one example, the location information of the terminal device is location information 1, and the first information includes: satellite information corresponding to each location information in location information A, location information B, location information C, and location information D. The terminal device obtains an optional location range based on location information 1 and the second distance, and if location information D is within the optional location range, then the area corresponding to location information D is determined to be the target area.

[0076] When different regions are represented based on different location ranges, a region may be understood as a region represented by the location range.

[0077] Here, the terminal device may determine a location range including the location information of the terminal device among the multiple location ranges in the first information.

[0078] In one example, the location information of the terminal device is location information 1, and the first information includes: satellite information corresponding to each location range in location range A, location range B, location range C, and location range D. Among them, if location information 1 is located in location range D, then the area corresponding to location range D is determined to be the target area.

[0079] In the case where different regions are represented based on different region identifiers, a region may be understood as a region corresponding to the region identifier, wherein the terminal device may store the location range of the region corresponding to each region identifier.

[0080] Here, the terminal device may determine that, in the location range corresponding to each of the multiple area identifiers in the first information, the area corresponding to the area identifier corresponding to the location range including the location information of the terminal device is the target area.

[0081] In one example, the location information of the terminal device is location information 1, and the first information includes: satellite information corresponding to each area identifier among area identifier A, area identifier B, area identifier C, and area identifier D, and the location ranges corresponding to the area identifiers among area identifier A, area identifier B, area identifier C, and area identifier D are location range A, location range B, location range C, and location range D, respectively. Among them, if location information 1 is located in location range D, then determining that the area corresponding to location range D indicates that the area corresponding to D is the target area.

[0082] After the terminal device determines the target area, it determines the second information using the satellite information of one or more first satellites corresponding to the target area in the first information. Here, the satellite information included in the second information can be defined as satellite information of the second satellite, that is, the second information includes satellite information of one or more second satellites.

[0083] The terminal device selects first target satellite information from satellite information of one or more second satellites included in the second information.

[0084] In a possible implementation manner, the second information includes satellite information of a second satellite, and the satellite information of the second satellite is determined as the first target satellite information.

[0085] In a possible implementation manner, the second information includes satellite information of a plurality of satellites, and the determining the first target satellite information based on the second information in S2013 includes:

[0086] According to the order of the plurality of second satellites, determining the first target satellite from the plurality of second satellites, wherein the satellite information of the first target satellite is the first target satellite information;

[0087] The order of the plurality of second satellites is determined based on the signal strength of each second satellite in the plurality of second satellites at a reference position, and the reference position is located in the target area.

[0088] For the first information, when one area corresponds to satellite information of multiple satellites, the first information also includes priority information or sorting information of the satellite information between the multiple satellites. The priority information or sorting information is used to characterize the sorting between the multiple satellites, that is, between the multiple satellites.

[0089] In the case where the target area corresponds to satellite information of multiple second satellites, the terminal device selects satellite information of a second satellite with the highest priority or the highest ranking from the multiple second satellites as the first target satellite information based on the ranking between the multiple second satellites, that is, selects the second satellite with the highest priority or the highest ranking from the multiple second satellites as the first target satellite information.

[0090] In one example, the second information includes satellite information of satellite A and satellite information of satellite B, and satellite A and satellite B are arranged in the order of satellite A, satellite B. The terminal device uses the satellite information of satellite A as the first target satellite information, and satellite A as the first target satellite. The terminal device establishes a connection with satellite A based on the satellite information of satellite A.

[0091] In an embodiment of the present application, the server may receive satellite information of satellites connected to the satellite communication devices when performing satellite communication and location information when performing satellite communication, as well as the signal strength or signal strength level of the satellite signal received by the satellite communication device from the connected satellite from multiple satellite communication devices. Here, the satellite signal received by the satellite communication device from the connected satellite can be understood as the satellite signal received by the satellite communication device at a reference position, and the reference position is the position of the satellite communication device. When the location information of multiple satellite information is the same, the server sorts the satellite information of the multiple satellites based on the signal strength or signal strength level corresponding to the multiple satellite information to obtain priority information or sorting information of each satellite information. The priority information or sorting information is added to the first information, and corresponds to the area corresponding to the location information.

[0092] In an embodiment of the present application, when the target area corresponds to the satellite information of multiple second satellites, it can be understood that the terminal device is in the intersection area of ​​the satellite coverage areas of multiple satellites, that is, the terminal device can access multiple satellites at the current location. At this time, the terminal device can select a satellite with better signal strength as the access satellite based on the sorting of multiple satellite information, so that the terminal device does not need to connect one by one or the randomly selected satellite is not the optimal choice, thereby improving the success rate of satellite access of the terminal device and improving the reliability of satellite connection.

[0093] In some embodiments, the terminal device also implements the following processing:

[0094] In the case of failure to establish a connection with the first target satellite, determining a second target satellite from the plurality of second satellites based on the order of the plurality of second satellites, wherein satellite information of the second target satellite is second target satellite information;

[0095] Based on the second target satellite information, a connection is established with the second target satellite to perform satellite communication based on the second target satellite.

[0096] The terminal device fails to establish a connection with the first target satellite based on the first target satellite information. At this time, based on the movement of the first target satellite, the terminal device may not be within the satellite coverage area of ​​the first target satellite.

[0097] In the case where the terminal device fails to establish a connection with the first target satellite based on the first target satellite information, the terminal device reselects a satellite for establishing a connection in the second information based on the location information, and the reselected satellite is the second target satellite, and the satellite information of the second target satellite can be referred to as the second target satellite information. Among them, the terminal device uses the satellite information of the second satellite with the highest priority or the highest ranking among the multiple second satellites corresponding to the target area except the first target satellite as the second target satellite information.

[0098] In one example, the second information includes satellite information of satellite A and satellite information of satellite B, and satellite A and satellite B are ordered as: satellite A, satellite B, then the terminal device uses the satellite information of satellite A as the first target satellite information, and satellite A as the first target satellite; when the terminal device fails to establish a connection with satellite A based on the satellite information of satellite A, the terminal device uses the satellite information of satellite B as the second target satellite information, and satellite B as the second target satellite, and the terminal device establishes a connection with satellite B based on the satellite information of satellite B.

[0099] It is understandable that, in the case where the terminal device fails to establish a connection with the second target satellite based on the second target satellite information, the terminal device reselects a satellite for establishing a connection based on the location information in the second information, and the reselected satellite is the third target satellite, and the satellite information of the third target satellite can be referred to as the third target satellite information. Among them, the terminal device uses the satellite information of the second satellite with the highest priority or the highest ranking among the multiple second satellites corresponding to the target area except the first target satellite and the second target satellite as the third target satellite information.

[0100] The satellite search method provided in the embodiment of the present application can quickly find the satellite to be connected again when the connection with the target satellite fails, thereby improving the satellite search speed.

[0101] In some embodiments, the terminal device also implements the following processing:

[0102] Deleting the first target satellite information in the second information;

[0103] Sending deletion indication information to the server, wherein the deletion indication information is used to instruct the server to delete the first target satellite information in the second information, and the deletion indication information is also used to trigger a target device to synchronously delete the first target satellite information in the second information, and the target device is a device that receives the first information from the server.

[0104] In an embodiment of the present application, when the terminal device fails to establish a connection with the first target satellite based on the first target satellite information, the first target information in the second information is deleted, that is, the invalid first target information is deleted, to avoid invalid selection of the first target satellite information based on the location information next time.

[0105] When deleting the first target satellite information, the terminal device sends deletion indication information to the server to instruct the server to synchronously delete the first target satellite information in the first information. The deletion indication information carries indication information indicating the first target satellite information, and the indication information may include the first target satellite information or the satellite identifier of the first target satellite.

[0106] When receiving the deletion instruction information, the server may delete the first target satellite information corresponding to the target area in the first information stored in the server. The server may also instruct the target device to delete the first target satellite information corresponding to the target area in the stored first information, where the target device is any device other than the current terminal device among the devices that receive the first information from the server.

[0107] In an embodiment of the present application, the server may synchronize the first information after deleting the first target satellite to the target device, so that the target device obtains the first information for deleting the first target satellite information in the second information. The server may also send synchronization deletion information to the target device, and after receiving the synchronization deletion information, the target device deletes the first target satellite information corresponding to the target area in the first information based on the received synchronization deletion information.

[0108] In one example, based on Figure 2 In the scenario shown in FIG. 1 , after the server determines the first information, the server may synchronize the first information to terminal device 201, terminal device 202, terminal device 203, terminal device 204, and terminal device 205, such as Figure 4 As shown, after the terminal device 205 deletes the first target satellite information corresponding to the target area in the first information stored in itself, it sends deletion indication information to the server 200. The server 200 deletes the first target satellite information corresponding to the target area in the first information based on the deletion indication information to obtain the updated first information, and synchronously sends the updated first information to the terminal device 201, the terminal device 202, the terminal device 203, and the terminal device 204.

[0109] In an embodiment of the present application, after a terminal device determines that the satellite information is invalid, in addition to deleting the invalid satellite information itself, the invalid satellite in the target device storing the first information is deleted through server synchronization to prevent other satellites from performing an invalid connection establishment process based on the invalid satellite information.

[0110] In some embodiments, the first target satellite information includes a first satellite resource corresponding to the first satellite; S103 establishes a connection with the first target satellite based on the first target satellite information, such as Figure 5 As shown, including:

[0111] S1031. Adjust the beam of the antenna of the terminal device based on the first satellite resource;

[0112] S1032. Receive a downlink synchronization signal of the first target satellite based on the adjusted antenna beam;

[0113] S1033. Establish an uplink and downlink service channel with the first target satellite based on the downlink synchronization signal of the first target satellite.

[0114] Here, the first satellite resource is a satellite resource of the first target satellite, and the satellite resource may include resources for connecting to the satellite, such as: pitch angle, azimuth angle, etc. The terminal device adjusts the beam of the antenna of the terminal device based on the first satellite resource, thereby adjusting the beam of the antenna to a beam capable of interacting with the first target satellite.

[0115] After the terminal device adjusts the antenna beam, it monitors the downlink synchronization signal of the first target satellite based on the adjusted beam. In the embodiment of the present application, the terminal device can determine whether the downlink synchronization signal of the first target satellite is received within the set first time period. If the downlink synchronization signal of the first target satellite is not received within the first time period, it can be determined that the connection with the first target satellite has failed; if the downlink synchronization signal of the first target satellite is received within the first time period, an uplink and downlink service channel is established with the first target satellite based on the received downlink synchronization signal.

[0116] In an embodiment of the present application, the downlink synchronization signal includes but is not limited to one or more of the following information: navigation message, pseudo-random noise code (PRN), carrier information, and spread spectrum code. The navigation message is the key information sent by the satellite navigation system to the user, which contains the satellite's orbital parameters, clock information, system time and other information. The terminal device can determine its own position and speed by parsing this information. The pseudo-random noise code (PRN) is a unique identifier used to distinguish different satellites in the satellite navigation system. Each satellite has a unique PRN code. The terminal device determines the source of the signal by identifying the PRN code. The carrier information includes the frequency and phase information of the carrier, which is used by the terminal device to capture and track the signal. The spread spectrum code is used to expand the spectrum of the signal and improve the anti-interference ability. The terminal device performs correlation operations with the local spread spectrum code through a matching filter to extract the navigation message and other useful information.

[0117] In the embodiment of the present application, the process of establishing a connection between the terminal device and the second target satellite may refer to the process of establishing a connection between the terminal device and the first target satellite, which will not be repeated here.

[0118] In some embodiments, the first satellite resource includes a first elevation angle and a first azimuth angle of the first target satellite, and S1031 adjusts the beam of the antenna of the terminal device based on the first satellite resource, including:

[0119] Acquiring posture information of the terminal device;

[0120] Determine a second pitch angle and a second azimuth angle for the terminal device based on the posture information, the first pitch angle and the first azimuth angle;

[0121] Based on the second elevation angle and the second azimuth angle, the beam direction of the antenna of the terminal device is controlled.

[0122] In the embodiment of the present application, the coordinate system of the first pitch angle and the first azimuth angle of the first target satellite is a reference coordinate system, and the reference coordinate system is a three-dimensional coordinate system. Here, the first pitch angle and the first azimuth angle can determine the target orientation of the first target satellite in the reference coordinate system.

[0123] In an embodiment of the present application, the first pitch angle may be the angle between a reference line pointing from the origin to the first target satellite and the horizontal plane of the reference coordinate system, the horizontal plane of the reference coordinate system may be the plane where the X-axis and the Y-axis are located, and the first azimuth angle may be the angle between the reference line and the X-axis vertical plane or the Y-axis vertical plane, wherein the X-axis vertical plane is the plane where the X-axis and the Z-axis are located, and the Y-axis vertical plane is the plane where the Y-axis and the Z-axis are located.

[0128] In the embodiment of the present application, the parameters of the antenna may include but are not limited to one or more of the following parameters: directivity, impedance matching, polarization mode, etc.
