Description

Technical Field

[0001] The present application relates to the field of satellite communication technology, and in particular to a satellite beam tracking method, device, electronic device and storage medium. Background Art

[0002] Satellite beam tracking technology can automatically follow the movement of the terminal, allowing the satellite to communicate with the terminal; since the satellite's beam range is limited, which may be only the size of a football field, in order to enable the target satellite to continuously provide communication services to the terminal, it is often necessary to continuously adjust the satellite's beam antenna.

[0003] However, the inventors of the present application discovered that the terminal may operate regularly or move irregularly, and that when the terminal is within the beam range of the satellite, the closer the terminal is to the edge of the beam range, the lower the communication quality. Therefore, as the beam range moves with the terminal, it is often necessary to continuously adjust the satellite's beam antenna, that is, to continuously output adjustment control signals. As a result, some of the continuous adjustment control instructions may be lost, which in turn causes inaccurate adjustment of the satellite's beam antenna. Summary of the invention

[0024] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] An embodiment of the present application provides a satellite beam tracking method, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server that provides cloud computing services; the server can be installed on a ground communication terminal or on a satellite.

[0027] Reference Figure 1 A satellite beam tracking method includes: step S101, step S102 and step S103, wherein: S101, determining the operating state of the target terminal and the initial beam range of the target satellite, wherein the operating state includes location information, operating direction, operating speed, and pre-operation trajectory.

[0028] In some embodiments, the target terminal may be a vehicle-mounted device or a mobile phone with a navigation function; the initial beam range is the maximum range that can be covered by the beam of the target satellite.

[0029] The electronic device sends an information acquisition instruction to the target terminal, and obtains its own location, namely, location information and running direction, running speed, navigation destination and other information from the target terminal through the Beidou system or GPS positioning system; then, the electronic device analyzes the location information, running direction and navigation destination, and predicts the path that the target terminal is about to run, namely, the pre-operation trajectory.

[0030] S102, determining a concentrated beam range corresponding to the target terminal based on the location information, the running direction, the running speed, the pre-running trajectory and the initial beam range.

[0031] In some embodiments, the concentrated beam range is a circular area and is located within the initial beam range; the beam power sent by the target satellite within the concentrated beam range is greater than the beam power sent by the target satellite within the non-concentrated beam range, that is, the communication quality of the target terminal within the concentrated beam range is greater than the communication quality within the non-concentrated beam range.

[0032] Different target terminals have different operating speeds. In order to enable the target terminal process to stay within the concentrated beam range for a longer time and reduce the adjustment frequency of the beam antenna of the target satellite, different concentrated beam ranges need to be set for different target terminals. In the process of determining the concentrated beam range, the location information of the target terminal can be used as the reference point, the operating direction, operating speed and operating trajectory can be used as reference data for determining the concentrated beam range corresponding to the target terminal, and the initial beam range can be used as the limiting condition for defining the concentrated beam range to construct the concentrated beam range corresponding to the target terminal.

[0033] In some embodiments, taking into account the possibility that the target terminal may temporarily change the running direction while running based on the running direction, the electronic device can first determine the relative position relationship between the position information and the initial beam range in the process of determining the concentrated beam range, and determine the range of the concentrated beam range in the same direction and different directions as the running direction based on the running speed, running direction and pre-running trajectory, that is, the distance from the position information to the edge of the concentrated beam range. The electronic device constructs the concentrated beam range through the determined distance.

[0034] S103, when the target terminal moves to the target edge point of the concentrated beam range, a beam adjustment instruction corresponding to the target edge point is generated, and based on the beam adjustment instruction, the target satellite is controlled to perform beam adjustment.

[0035] In some embodiments, after the electronic device constructs a concentrated beam range that is compatible with the target terminal, it begins to monitor the operation of the target terminal in real time. When the target terminal moves to the target edge point of the concentrated beam range, it indicates that the target terminal is about to move out of the concentrated beam range. In order to ensure the communication quality between the target terminal and the target satellite, it is necessary to track the target terminal at this time, that is, adjust the angle of the beam antenna of the target satellite, that is, the electronic device generates a beam adjustment instruction, and controls the target satellite to perform beam adjustment based on the beam adjustment instruction; thereby, by constructing a concentrated beam range that is compatible with the target terminal, the communication quality between the target terminal and the target satellite is improved, and at the same time, when the target terminal is about to move out of its compatible concentrated beam range, the beam antenna of the target satellite is adjusted to reduce the adjustment frequency of the beam antenna of the target satellite.

[0036] In some embodiments, the target edge point is a point on the edge line of the concentrated beam range; the target edge point can be set to multiple, and when the target terminal reaches different target edge points, the electronic device generates a beam adjustment instruction corresponding to the target edge point, and controls the target satellite to perform adaptive beam range adjustment through the beam adjustment instruction. For example, when the target edge point is an edge point on the edge line of the concentrated beam range close to the running direction of the target terminal, the electronic device generates a beam adjustment instruction that represents the control of the target satellite's beam antenna to adjust toward the running direction.

[0037] In step S101, the operating status of the target terminal and the initial beam range of the target satellite are determined, including: obtaining total beam ranges corresponding to multiple initial satellites; determining departure distances corresponding to the multiple initial satellites based on the position information and the total beam range, and determining multiple departure times corresponding to the multiple initial satellites based on the operating speed; based on the multiple departure times, selecting the target satellite from the multiple initial satellites, and defining the corresponding total beam range as the initial beam range.

[0038] In some embodiments, the electronic device first obtains the total beam ranges corresponding to multiple initial satellites, and determines the relative position relationship between the position information and the multiple total beam ranges, and determines the distance between the position information and the edge lines of the target terminal in different directions within the total beam range, that is, the departure distance; based on the determined target terminal, based on the current speed, the time it takes for the target terminal to reach the edge lines in different directions, that is, the departure time; thereby obtaining multiple departure times corresponding to the multiple initial satellites; then, the electronic device calculates the amplitude values ​​of the multiple departure times corresponding to each initial satellite, defines the initial satellite corresponding to the minimum amplitude value as the target satellite, and obtains the initial beam range of the initial satellite.

[0039] In step S102, based on the position information, the running direction, the running speed, the pre-running trajectory and the initial beam range, the concentrated beam range corresponding to the target terminal is determined, including: based on the position information, determining the relative position information between the target terminal and the initial beam range; based on the relative position information and the running speed, determining the first distance information in the same direction as the running direction, wherein the first distance information is the distance information with the position information as the origin and the same as the running direction; based on the running direction and the pre-running trajectory, determining the second distance information in a direction perpendicular to the running direction and in a reverse direction, wherein the second distance information is the distance information with the position information as the origin and the direction perpendicular to the running direction and in a reverse direction; based on the position information, the first distance information and the second distance information, constructing the concentrated beam range.

[0040] In some embodiments, the electronic device inputs the position information and the initial beam range of the target terminal into a two-dimensional model, determines the relative position relationship between the target terminal and the initial beam range, and obtains the relative position information; then the electronic device determines the first distance information in the same direction as the running direction of the target terminal based on the relative position information and the running speed, wherein the electronic device determines the running level corresponding to the target terminal based on the running speed, and retrieves the preset distance corresponding to the running level; the electronic device defines the preset distance as the first distance information, and subsequently the electronic device constructs the range of the concentrated beam range corresponding to the target terminal close to the running direction based on the first distance information; at the same time, the electronic device determines the second distance information in a direction perpendicular to the running direction and in the opposite direction based on the running direction and the pre-running trajectory, wherein the electronic device uses the driving path of the pre-running trajectory as reference data for whether the target terminal is running in a straight line, and further determines the distances in two directions perpendicular to the running direction and in the direction opposite to the running direction based on the reference data; the electronic device constructs the range of two directions perpendicular to the running direction and in the direction opposite to the running direction of the concentrated beam range corresponding to the target terminal based on the second distance information.

[0041] In some embodiments, based on the relative position information and the running speed, the first distance information in the same direction as the running direction is determined, including: judging whether the relative position information satisfies a preset relative position range; determining the speed level corresponding to the running speed and the first preset distance information corresponding to the speed level; when the relative position information satisfies the preset relative position range, using the first preset distance information as the first distance information in the same direction as the running direction.

[0042] In some embodiments, the electronic device sets in advance the association between different speeds, different speed levels and distance information. For example, when the running speed is within a first speed range, its associated speed level is a first level, and its associated preset distance information is a first preset distance; when the speed is within a second speed range, its associated speed level is a second level, and its associated preset distance information is a second preset distance, wherein the first speed range is greater than the second preset speed range, the speed level of the first level is greater than the speed level of the second level, and the first preset distance is greater than the second preset distance.

[0043] The electronic device sets a preset relative position range, and determines whether the relative position information satisfies the preset relative position range, that is, determines whether the position of the target terminal is within a specific range within the initial beam range. When the electronic device determines that the relative position information satisfies the preset relative position range, the electronic device uses the determined first preset distance information as the first distance information in the same direction as the running direction.

[0044] In some embodiments, the pre-operation trajectory is the operation trajectory of the target terminal within a preset time period, wherein the preset time period is the time taken by the target terminal to enter the initial beam range and leave the initial beam range based on the operation speed; the direction perpendicular to the operation direction includes a first vertical direction and a second vertical direction.

[0045] In some embodiments, based on the running direction and the pre-running trajectory, second distance information in a direction perpendicular to and in a reverse direction of the running direction is determined, including: when the pre-running trajectory is a straight line running, calling the second preset distance information, and using the second preset distance information as the second distance information in a direction perpendicular to and in a reverse direction of the running direction; when the pre-running trajectory is a non-straight line running, calling the third preset distance information, and using the second preset distance information as the second distance information in a first direction perpendicular to and in a reverse direction of the running direction, and using the third preset distance information as the second distance information in a second direction perpendicular to the running direction.

[0046] In some embodiments, the electronic device determines whether the pre-operation trajectory is a straight line operation, and when it is determined that the pre-operation trajectory is a straight line operation, it indicates that the target terminal will not turn or make a U-turn within a preset time period. Therefore, when determining the concentrated beam range of the target terminal, the range on both sides and in the opposite direction of the target terminal can be set relatively small; the electronic device calls the second preset distance information and uses the second preset distance information as the second distance information in two directions perpendicular to the running direction and in the opposite direction of the pre-operation direction.

[0047] When the electronic device determines that the pre-operation trajectory is a non-straight line operation, it indicates that the target terminal will turn within a preset time period. Therefore, when determining the concentrated wave beam range of the target terminal, the range of the vertical side where the target terminal turns can be set larger than the range of another vertical measurement and the reverse range; the electronic device calls the third preset distance information, and uses the second preset distance information as the first vertical direction and the second distance information in the reverse direction of the running direction, and uses the third preset distance information as the second distance information in the second vertical direction of the running direction; wherein the first preset distance information is greater than the third distance information and greater than the second distance information; the first vertical direction is the direction away from the side where the target terminal turns, and the second vertical direction is the direction close to the side where the target terminal turns.

[0048] In some embodiments, a concentrated beam range is constructed based on the position information, the first distance information, and the second distance information, including: generating a first vertical line at the end point of the first distance information, and generating a second vertical line at the end point of the second distance information; using the intersection of the first vertical line and the second vertical line as an edge point, constructing a circular area, and defining the circular area as the concentrated beam range.

[0049] In some embodiments, the electronic device calls the location information, first location information and second distance information of the target terminal into a two-dimensional model, constructs a positional relationship between the location information, the first distance information and the second distance information, and then the electronic device determines the end point of the first distance information and generates a first vertical line of the first distance information at the end point. At the same time, the electronic device determines the end point of the second distance information and generates a second vertical line of the second distance information at the end point; the electronic device uses the intersection between the first vertical line and the second vertical line as an edge point to construct a circular area, and defines the circular area as a concentrated beam range.

[0050] In step S103, when the target terminal moves to a target edge point of the concentrated beam range, a beam adjustment instruction corresponding to the target edge point is generated, including: when the target terminal moves to a first target edge point of the concentrated beam range, a first beam adjustment instruction is generated, wherein the first target edge point is an edge point on a line between a first target edge point having the same running direction as the target terminal and the position information; the first beam adjustment instruction is a beam adjustment instruction for moving the concentrated beam range along the running direction; when the target terminal moves to a second target edge point of the concentrated beam range, a second beam adjustment instruction is generated, wherein the second target edge point is an edge point on a line between a second edge point having a different running direction from the target terminal and the position information; the second beam adjustment instruction is a beam adjustment instruction for locating the target terminal at the center point of the concentrated beam range.

[0051] In some embodiments, when the electronic device monitors in real time that the target terminal moves to the first target edge point of the concentrated beam, it indicates that the target terminal is moving in a straight line. At this time, the electronic device generates a first beam adjustment instruction, and controls the target satellite based on the first beam adjustment instruction, so that the concentrated beam range corresponding to the target satellite moves along the running direction until the relative position relationship between the current target terminal position and the concentrated beam range is consistent with the relative position relationship between the two before the concentrated beam range of the target satellite is controlled to move.

[0052] When the electronic device monitors in real time that the target terminal moves to the second target edge point of the concentrated beam, it indicates that the target terminal is moving non-linearly. At this time, the electronic device generates a second beam adjustment instruction and controls the target satellite based on the second beam adjustment instruction so that the center point of the concentrated beam range corresponding to the target satellite coincides with the position of the current target terminal.
