[0046] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] Please see Figures 1 to 3 As shown, this invention provides a shipborne broadband satellite communication control system, which functionally comprises a control correction unit 3, a transceiver unit 1, and an execution unit 2. The control correction unit 3 collects and analyzes the operational adjustment status of the communication antenna and precisely controls the communication antenna through the transceiver unit 1 and the execution unit 2.

[0049] Please see Figure 2 and 4As shown, in this scheme, the control correction unit 3 can first execute step S1 to obtain the actual and target azimuth angles of the communication antenna in three dimensions at the current moment, and calculate the theoretical difference angle of the azimuth angles in the three dimensions of the communication antenna at the current moment. The three azimuth angles are the azimuth angle, elevation angle, and polarization angle of the communication antenna. Specifically, it can first execute step S11 to obtain the ephemeris of the communication satellite. Next, it can execute step S12 to obtain the current position of the ship in real time. Next, it can execute step S13 to obtain the actual azimuth angles of the communication antenna in three dimensions at the current moment, namely the actual azimuth angle, actual elevation angle, and actual polarization angle. Next, it can execute step S14 to combine the radio specification attributes of the communication antenna, and according to the ephemeris of the communication satellite and the current position of the ship in the berth, obtain the target azimuth angles in three dimensions at the current moment to achieve the optimal communication state, namely the target azimuth angle, target elevation angle, and target polarization angle. Finally, it can execute step S15 to obtain the theoretical difference angle of the azimuth angles in the three dimensions of the communication antenna at the current moment based on the difference between the target and actual azimuth angles in the three dimensions of the communication antenna at the current moment.

[0050] Please see Figure 2 As shown, after executing step S1, the control correction unit 3 in this scheme can continue to execute step S2 to obtain the preset correction amount of the azimuth angle in each dimension under different actual azimuth angles and theoretical difference angle states. Next, step S3 can be executed to substitute the actual azimuth angle and theoretical difference angle of the three dimensions of the communication antenna at the current moment into the correction amount of the azimuth angle in each dimension under different actual azimuth angles and theoretical difference angle states to obtain the execution adjustment angle of the azimuth angle in the three dimensions of the communication antenna at the current moment.

[0051] Please see Figure 5 As shown, in the specific process of calculating the above-mentioned adjustment angle, firstly, step S31 can be executed to substitute the actual azimuth angle and theoretical difference angle of the three-dimensional azimuth angle of the communication antenna at the current moment into the correction amount of the azimuth angle of each dimension under different actual azimuth angle and theoretical difference angle states to obtain the correction amount of the azimuth angle of the communication antenna at the current moment in the three dimensions. Then, step S32 can be executed to superimpose the theoretical difference angle of the azimuth angle of the three-dimensional azimuth angle of the communication antenna at the current moment with the correction amount of the corresponding azimuth angle in each dimension to obtain the adjustment angle of the azimuth angle of the communication antenna at the current moment in the three dimensions.

[0052] Please see Figure 2As shown, after executing step S3, the control correction unit 3 in this scheme can continue to execute step S4 to obtain the actual azimuth angles of the three dimensions of the communication antenna at the current moment after the execution adjustment angle. Next, step S5 can be executed to update the correction amount of the azimuth angle of each dimension under different actual azimuth angles and theoretical difference angle states based on the actual azimuth angles of the three dimensions of the communication antenna at the current moment after the execution adjustment angle.

[0053] Please see Figure 6 and 7 As shown, the motion performance of a communication antenna varies under different environmental conditions. For example, in high humidity and high salt spray conditions, the antenna rotation lubrication is insufficient, usually requiring a large correction. Furthermore, the error in antenna rotation is closely related to the rotation amplitude and initial angle; therefore, the correction amount is correlated with the actual azimuth angle and the theoretical difference angle. In view of this, to update the correction amount for each dimension of the azimuth angle under different actual azimuth angle and theoretical difference angle conditions, step S51 can first be executed to obtain the correct correction amount for the three dimensions of the azimuth angle under the current actual azimuth angle and theoretical difference angle condition based on the actual azimuth angle after angle adjustment and the target azimuth angle at the current moment. Next, step S52 can be executed to summarize the correct correction amounts for the three dimensions of the azimuth angle at different times in the current moment under the current actual azimuth angle and theoretical difference angle condition, obtaining the correct correction amount for each dimension of the azimuth angle applicable to the current time period under the current actual azimuth angle and theoretical difference angle condition.

[0054] Please see Figure 7 As shown, in practice, the environmental factors affecting the motion performance of communication antennas are mainly temperature, humidity, and salinity, specifically sea fog salinity. Therefore, data with the same environmental factors can be found. Specifically, first, step S521 can be executed to obtain the environmental parameters of the sea area where the communication antenna is located at the current moment. These environmental parameters include temperature, humidity, and salinity. Next, step S522 can be executed to obtain the environmental records of the environmental parameters of the sea area where the communication antenna is located. Next, step S523 can be executed to retrieve multiple historical time periods that are consistent with the environmental parameters of the sea area where the communication antenna is located at the current moment from the environmental records. Finally, step S524 can be executed to use the correct correction values ​​for the actual azimuth angle and theoretical difference angle state of each dimension of the azimuth angle within the multiple historical time periods that are consistent with the environmental parameters of the sea area where the communication antenna is located at the current moment as the correct correction values ​​for the actual azimuth angle and theoretical difference angle state of each dimension of the azimuth angle applicable to the current time period.

[0055] Please see Figures 7 to 9As shown, step S53 can be executed next. For the direction angle of each dimension, the correct correction amount of the updated direction angle of each dimension under different actual direction angles and theoretical difference angle states can be obtained based on the correct correction amount applicable to multiple sets of actual direction angles and theoretical difference angle states for the current time period.

[0056] For ease of discussion, the following describes the operation of the azimuth angle for each dimension. Referring to Figures 8 and 9, firstly, step S531 calculates the difference between each set of actual azimuth angles and theoretical difference angle combinations applicable to the current time period, obtaining multiple sets of actual azimuth angles and theoretical difference angle combinations consistent with the actual azimuth angle and theoretical difference angle of the communication antenna at the current moment. Specifically, firstly, step S5311 selects several combinations as variable core combinations from each set of actual azimuth angles and theoretical difference angle combinations applicable to the current time period. Next, step S5312 also uses the current moment's actual azimuth angle and theoretical difference angle combination as a fixed core combination. Next, step S5313 calculates and obtains the cumulative value of the actual azimuth angle difference and theoretical difference angle difference between each core combination and each other set of actual azimuth angles and theoretical difference angle combinations as the inter-combination difference degree. Next, step S5314 assigns each other set of actual azimuth angles and theoretical difference angle combinations to the same combination pool along with the core combination with the smallest inter-combination difference degree.

[0057] Since the differences within the combination pools at this point may be significant, consistency verification is required. First, step S5315 is executed: for each variable core combination's combination pool, the mean actual angle and mean theoretical difference angle of each set of actual angles and theoretical difference angles contained within it are calculated. Next, step S5316 is executed: the combination of actual angles and theoretical difference angles with the smallest difference between the combinations in the combination pool containing each variable core combination and the combination with the mean actual angle and mean theoretical difference angle is used as the updated variable core combination. Next, step S5317 is executed: it is determined whether the updated variable core combination has changed. If "yes," it indicates insufficient consistency, and steps S5311 to S5317 are executed to continuously update the combination pools and variable core combinations; if "no," it indicates sufficient consistency, and step S5318 is executed: all combinations of actual angles and theoretical difference angles contained in the combination pool containing the fixed core combination are used as multiple combinations of actual angles and theoretical difference angles that are consistent with the actual angle and theoretical difference angle of the communication antenna at the current moment.

[0058] Next, step S532 can be executed to take the mean or median of the correct correction values ​​corresponding to multiple sets of consistent actual orientation angles and theoretical difference angles as the updated correction values ​​corresponding to multiple sets of consistent actual orientation angles and theoretical difference angles. Finally, step S533 can be executed to summarize the updated correction values ​​for each dimension of the orientation angle under different actual orientation angles and theoretical difference angles.

[0059] To supplement the explanation of the implementation process of steps S5311 to S5318 above, source code for some functional modules is provided, with comparative explanations in the comments. To avoid data leakage involving trade secrets, data that does not affect the implementation of the solution has been anonymized; the same applies below.

[0179] Please refer to Figures 1 to 3 In the scheme, a shipboard broadband satellite communication control terminal includes a transceiver unit 1 and an execution unit 2. The transceiver unit 1 needs to perform step S011 to send the actual direction angle of the three-dimensional direction angle of the communication antenna at the current time before the control correction unit 3 calculates and analyzes. Next, step S012 can be performed to receive the execution adjustment angle of the three-dimensional direction angle of the communication antenna at the current time. Then, the execution unit 2 in the terminal can perform step S021 to execute the execution adjustment angle of the three-dimensional direction angle of the communication antenna at the current time. Finally, the transceiver unit in the terminal feeds back to the control correction unit 3, that is, step S013 is performed to send the actual direction angle of the three-dimensional direction angle of the communication antenna after executing the execution adjustment angle at the current time.
