Description

Technical Field

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

[0002] Satellite beam tracking technology can automatically follow the movement of a terminal to enable communication between the satellite and the terminal; since the beam range of the satellite is limited, perhaps only the size of a football field, therefore, in order to enable the target satellite to continuously provide communication services to the terminal, it is often necessary to continuously adjust the beam antenna of the satellite.

[0003] However, the inventors of the present application found that the terminal operation has both regular operation situations and irregular movement situations, and moreover, when the terminal is within the beam range of the satellite, the closer the terminal is to the edge area of the beam range, the lower its communication quality. Therefore, during the movement of the beam range following the terminal, it is often necessary to continuously adjust the beam antenna of the satellite, that is, continuously output adjustment control signals. Therefore, there are situations such as loss of some adjustment control instructions in the continuous adjustment control instructions, which in turn causes inaccurate adjustment of the beam antenna of the satellite.

[0039] The following further Figures 1 - 3 describes the present application in detail with reference to the

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0041] An embodiment of the present application provides a satellite beam tracking method, which can be executed by an electronic device. Among them, the electronic device can be a server. Among them, the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server providing cloud computing services; the server can be installed in a ground communication terminal or on a satellite.

[0042] Referring to Figure 1 , a satellite beam tracking method includes: step S101, step S102, and step S103, where

[0043] S101, determining the operating state of the target terminal and the initial beam range of the target satellite, where the operating state includes position information, operating direction, operating speed, and pre-operating trajectory.

[0044] In some embodiments, the target terminal can be an in-vehicle device with a navigation function, a mobile phone, etc.; the initial beam range is the maximum range that the beam of the target satellite can cover.

[0045] The electronic device sends an information acquisition instruction to the target terminal, and obtains its own location, i.e., location information, running direction, running speed, navigation destination, etc. from the target terminal through the Beidou system or GPS positioning system; Subsequently, the electronic device analyzes the location information, running direction, and navigation destination to predict the path that the target terminal is about to run, i.e., the pre-running trajectory.

[0046] S102. Determine the concentrated beam range corresponding to the target terminal based on the location information, running direction, running speed, pre-running trajectory, and initial beam range.

[0047] In some embodiments, the concentrated beam range is a circular area and is located within the initial beam range; the beam power transmitted by the target satellite within the concentrated beam range is greater than the beam power transmitted by the target satellite outside the concentrated beam range, that is, the communication quality of the target terminal located within the concentrated beam range is greater than the communication quality outside the concentrated beam range.

[0048] The running speeds of different target terminals are different. In order to enable the target terminal 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; During the process of determining the concentrated beam range, the location information of the target terminal can be used as a reference point, the running direction, running speed, and running 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 a limiting condition for delimiting the concentrated beam range to construct the concentrated beam range corresponding to the target terminal.

[0049] In some embodiments, considering the possibility that the target terminal may temporarily change its running direction during the running process based on the running direction, when the electronic device determines the concentrated beam range, it can first determine the relative position relationship between the location information and the initial beam range, and determine the ranges in the same direction and different directions of the concentrated beam range based on the running speed, running direction, and pre-running trajectory, that is, the distance from the location information to the edge of the concentrated beam range. The electronic device constructs the concentrated beam range through the determined distance.

[0050] S103. When the target terminal moves to the target edge point of the concentrated beam range, generate a beam adjustment instruction corresponding to the target edge point, and control the target satellite to perform beam adjustment based on the beam adjustment instruction.

[0051] In some embodiments, after the electronic device constructs a centralized beam range adapted to the target terminal, it starts to monitor the operating conditions of the target terminal in real time. When the target terminal moves to the target edge point of the centralized beam range, it indicates that the target terminal is about to move out of the centralized beam range at this time. To ensure the communication quality between the target terminal and the target satellite, the target terminal needs to be tracked at this time, that is, the angle of the beam antenna of the target satellite is adjusted. 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 centralized beam range adapted to the target terminal, the communication quality between the target terminal and the target satellite is improved. At the same time, when the target terminal is about to move out of its adapted centralized beam range, the beam antenna of the target satellite is adjusted to reduce the adjustment frequency of the beam antenna of the target satellite.

[0052] In some embodiments, the target edge point is a point on the edge line of the centralized beam range; multiple target edge points can be set. 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 centralized beam range close to the running direction of the target terminal, the electronic device generates a beam adjustment instruction indicating that the beam antenna of the target satellite is adjusted towards the running direction.

[0053] In step S101, determining the operating state of the target terminal and the initial beam range of the target satellite includes: obtaining the total beam ranges corresponding to multiple initial satellites respectively; based on the position information and the total beam ranges, determining the departure distances corresponding to multiple initial satellites respectively, and based on the running speed, determining the multiple departure durations corresponding to multiple initial satellites respectively; based on the multiple departure durations, screening out the target satellite from the multiple initial satellites and defining the corresponding total beam range as the initial beam range.

[0054] In some embodiments, the electronic device first obtains the total beam ranges corresponding to multiple initial satellites respectively, determines the relative position relationship between the position information and the multiple total beam ranges respectively, and determines the distance between the target terminal and the edge lines in different directions within the position information and the total beam range, that is, the departure distance; based on the determined departure distance of the target terminal, the time taken for the target terminal to reach the edge lines in different directions based on the current speed, that is, the departure duration; thereby obtaining the multiple departure durations corresponding to multiple initial satellites respectively; subsequently, the electronic device calculates the amplitude values of the multiple departure durations corresponding to each initial satellite, and defines the initial satellite corresponding to the minimum amplitude value as the target satellite and obtains the initial beam range of the initial satellite.

[0055] In step S102, based on the location information, running direction, running speed, pre-running trajectory, and initial beam range, determine the concentrated beam range corresponding to the target terminal, including: based on the location information, determine the relative location information between the target terminal and the initial beam range; based on the relative location information and the running speed, determine the first distance information in the direction same as the running direction, where the first distance information is the distance information in the direction same as the running direction with the location information as the origin; based on the running direction and the pre-running trajectory, determine the second distance information in the direction perpendicular to and opposite to the running direction, where the second distance information is the distance information in the direction perpendicular to and opposite to the running direction with the location information as the origin; based on the location information, the first distance information, and the second distance information, construct the concentrated beam range.

[0056] In some embodiments, the electronic device inputs the location information of the target terminal and the initial beam range into a two-dimensional model, determines the relative position relationship between the target terminal and the initial beam range, and obtains the relative location information; subsequently, the electronic device determines the first distance information in the direction same as the running direction of the target terminal based on the relative location information and the running speed, where the electronic device determines the running level corresponding to 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 the direction perpendicular to and opposite to the running direction based on the running direction and the pre-running trajectory, where the electronic device uses the driving path of the pre-running trajectory as the reference data for whether the target terminal runs in a straight line, and further determines the distances in the two directions perpendicular to the running direction and the direction opposite to the running direction based on the reference data; the electronic device constructs the ranges of the two directions perpendicular to the running direction and the direction opposite to the running direction of the concentrated beam range corresponding to the target terminal based on the second distance information.

[0057] In some embodiments, based on the relative location information and the running speed, determining the first distance information in the direction same as the running direction includes: determining whether the relative location information satisfies a preset relative location range; determining the speed level corresponding to the running speed and the first preset distance information corresponding to the speed level; in the case where the relative location information satisfies the preset relative location range, using the first preset distance information as the first distance information in the direction same as the running direction.

[0058] In some embodiments, the electronic device pre-sets the association between different speeds, different speed levels, and distance information. For example, when the running speed is within the first speed range, the associated speed level is the first level, and the associated preset distance information is the first preset distance; when the speed is within the second speed range, the associated speed level is the second level, and the associated preset distance information is the second preset distance, where 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.

[0059] The electronic device sets a preset relative position range, and the electronic device determines whether the relative position information meets 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 meets the preset relative position range, the electronic device uses the determined first preset distance information as the first distance information in the direction same as the running direction.

[0060] In some embodiments, the pre-running trajectory is the running trajectory of the target terminal within a preset time period, where the preset time period is the time taken for the target terminal to enter and leave the initial beam range based on the running speed; the direction perpendicular to the running direction includes a first perpendicular direction and a second perpendicular direction.

[0061] In some embodiments, based on the running direction and the pre-running trajectory, determining the second distance information in the direction perpendicular to the running direction and in the reverse direction includes: when the pre-running trajectory is a straight-line run, invoking the second preset distance information and using the second preset distance information as the second distance information in the direction perpendicular to the running direction and in the reverse direction; when the pre-running trajectory is a non-straight-line run, invoking the third preset distance information, using the second preset distance information as the second distance information in the first perpendicular direction to the running direction and in the reverse direction, and using the third preset distance information as the second distance information in the second perpendicular direction to the running direction.

[0062] In some embodiments, the electronic device determines whether the pre-running trajectory is a straight-line run. When it is determined that the pre-running trajectory is a straight-line run, it indicates that the target terminal will not turn or reverse within the preset time period. Therefore, when determining the concentrated beam range of the target terminal, the ranges on both sides and in the reverse direction of the target terminal can be set relatively smaller; the electronic device invokes the second preset distance information and uses the second preset distance information as the second distance information in the two directions perpendicular to the running direction and in the reverse direction of the pre-running direction.

[0063] When the electronic device determines that the pre-operating trajectory is non-linear, it indicates that the target terminal will turn within the preset time period. Therefore, when determining the concentrated beam range of the target terminal, the range on the vertical side where the target terminal turns can be set to be larger than the range on the other vertical side and the reverse range; the electronic device calls the third preset distance information, and uses the second preset distance information as the second distance information in the first vertical direction and 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; among them, the first preset distance information is greater than the third distance information is 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.

[0064] In some embodiments, based on the position information, the first distance information, and the second distance information, a concentrated beam range is constructed, 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 point between the first vertical line and the second vertical line as the edge point, constructing a circular area, and defining the circular area as the concentrated beam range.

[0065] In some embodiments, the electronic device transfers the position information, the first position information, and the second distance information of the target terminal into a two-dimensional model to construct the positional relationship between the position information, the first distance information, and the second distance information. Subsequently, the electronic device determines the end point of the first distance information and generates a first vertical line of the first distance information at this 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 this end point; the electronic device uses the intersection point between the first vertical line and the second vertical line as the edge point to construct a circular area, and defines the circular area as the concentrated beam range.

[0066] In step 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, including: when the target terminal moves to the first target edge point of the concentrated beam range, a first beam adjustment instruction is generated, where the first target edge point is the edge point on the connection line between the first target edge point in 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 the second target edge point of the concentrated beam range, a second beam adjustment instruction is generated, where the second target edge point is the edge point on the connection line between the second edge point in a different running direction from the target terminal and the position information; the second beam adjustment instruction is a beam adjustment instruction for making the target terminal located at the center point of the concentrated beam range.

[0067] 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 running 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 range of the concentrated beam corresponding to the target satellite moves along the running direction until the relative position relationship between the current position of the target terminal and the range of the concentrated beam is the same as the relative position relationship between the two before controlling the movement of the range of the concentrated beam of the target satellite.

[0068] 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 not running in a straight line. 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 range of the concentrated beam corresponding to the target satellite coincides with the position of the current target terminal.
