[0002] With the development of aviation communication technology, Air-to-Ground (ATG) communication systems are widely used in scenarios such as in-flight internet and remote aircraft monitoring because they can provide high-speed, continuous communication services for aircraft in flight. Precise alignment of the ground antenna beam with the aircraft is a core prerequisite for ensuring ATG communication quality. During flight, aircraft experience real-time changes in altitude, speed, and heading, and are affected by factors such as airflow, terrain obstruction, and electromagnetic interference. Therefore, rapid tracking and alignment of the ground antenna beam are essential to avoid communication link interruptions and signal attenuation.

[0003] Traditional ground antenna beams are typically aligned with aircraft using a mechanical turntable that drives the antenna cone to scan and jitter track. This method not only results in low alignment accuracy and slow response speed, but is also susceptible to environmental interference, leading to tracking loss. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] In one exemplary embodiment, such as Figure 1 As shown, a ground-to-air communication control system is provided, including: a communication mechanism 10, an adjustment mechanism 20, a sensing mechanism 30, and a control mechanism 40. The communication mechanism 10 establishes a communication connection between ground communication equipment and an airborne communication target through a preset frequency band.

[0048] The adjustment mechanism 20 includes a first adjustment component and a second adjustment component. The first adjustment component is used to adjust the azimuth angle of the communication mechanism, and the second adjustment component is used to adjust the pitch angle of the communication mechanism.

[0049] The sensing mechanism 30 is used to collect multi-dimensional data of the airborne communication object during the process of ground communication equipment communicating with the airborne communication object through the communication mechanism 10; the multi-dimensional data includes three-dimensional coordinates, communication quality data and attitude change data.

[0050] The control mechanism 42 communicates with the communication mechanism 10, the adjustment mechanism 20, and the sensing mechanism 30 respectively. It is used to obtain the reference communication angle at the current moment and the predicted communication angle at the next moment based on the installation position coordinates and multi-dimensional data of the communication mechanism 10; generate a lead adjustment command based on the reference communication angle and the predicted communication angle; drive the adjustment mechanism 20 to adjust the communication angle of the communication mechanism 10 through the lead adjustment command; and adjust the beamwidth of the communication mechanism 10 based on the relative distance between the communication mechanism 10 and the air communication object; the communication angle includes azimuth and pitch angle.

[0051] During initial startup, all components are initialized and reset. For example, the adjustment mechanism 20 is reset to its initial azimuth and elevation angles of 0°, the beamwidth of the communication mechanism 10 is adjusted to its initial value of 1°, and preset parameters are configured, including: beam alignment accuracy threshold, communication link quality threshold, rotational angular velocity of the adjustment mechanism 20, and sampling frequency of the sensing mechanism 30. Simultaneously, the ground communication equipment establishes a communication connection with the airborne communication target through the communication mechanism 10, completing the identification of the airborne communication target and preparing for data exchange.

[0052] Furthermore, during communication, the sensing mechanism 30 continuously collects the three-dimensional coordinates, communication quality data, and attitude change data of the airborne object, providing comprehensive input for tracking control. The control mechanism 40 calculates the reference communication angle at the current moment based on the installation position coordinates of the communication mechanism 10 and the multi-dimensional data collected by the sensing mechanism 30. It then predicts the predicted communication angle for the next moment by considering the speed, heading, and attitude changes of the airborne communication object. Based on the difference between the reference and predicted communication angles, the control mechanism 40 generates a lead adjustment command. This command allows the communication mechanism to point ahead, offsetting movement delays and avoiding tracking lag. The control mechanism 40 drives the adjustment mechanism 20 to control the azimuth and pitch angle rotation of the communication mechanism 10 through the lead adjustment command, ensuring that the beam of the communication mechanism 10 is precisely aligned with the airborne communication object. The control mechanism 40 adaptively adjusts the beamwidth based on the real-time relative distance between the communication mechanism 10 and the airborne communication object. For example, at greater distances, the beam is narrowed to increase gain; at closer distances, the beam is widened to expand the acquisition range, ensuring stable communication throughout the entire process.

[0053] In an exemplary embodiment, the system further includes a monitoring mechanism 50. The monitoring mechanism 50 is used to collect link quality data of the communication connection and is configured to send an alarm signal to the control mechanism 40 when the link quality data does not meet signal requirements. This causes the control mechanism 40, triggered by the alarm signal, to generate an angle fine-tuning command based on the current communication angle and the link quality data. The angle fine-tuning command drives the adjustment mechanism 20 to adjust the communication angle of the communication mechanism 10 and adjusts the beamwidth of the communication mechanism 10 based on the current relative distance. The link quality data includes reference signal received power, signal-to-interference-plus-noise ratio (SIR), and bit error rate (BER).

[0054] The monitoring unit 50 continuously collects link quality data between the ground communication equipment and the airborne object, including three core indicators: reference signal received power, signal-to-interference-plus-noise ratio (SIR), and bit error rate (BER). It compares the collected link quality data with preset threshold conditions to determine the stability and reliability of the current communication link. When the link quality data does not meet the signal requirements (e.g., low reference signal received power, insufficient SIR, or high BER), the monitoring unit 50 immediately sends an alarm signal to the control unit 40, notifying the system of abnormal communication quality. Upon receiving the alarm signal, the control unit 40 generates an angle fine-tuning command based on the current communication angle and the abnormal link quality data. This command drives the adjustment unit 20 to make precise small-range corrections to the azimuth and pitch angles of the communication unit 10. Simultaneously, it adaptively adjusts the beamwidth based on the real-time relative distance between the communication unit and the airborne object, quickly restoring the communication link quality to a qualified range and preventing communication interruption or tracking loss. Through continuous data collection and judgment by the monitoring unit 50, the system achieves real-time communication quality assurance while maintaining tracking alignment, forming a complete closed loop of "alignment-monitoring-correction-stabilization."

[0055] In an exemplary embodiment, the system further includes a transmission mechanism 60. One end of the transmission mechanism 60 is connected to the communication mechanism 10, and the other end is connected to a ground communication device. The transmission mechanism 60 includes a first channel and a second channel. The first channel is used to transmit communication signals between the ground communication device and the airborne communication object, and the second channel is used to transmit control signals sent by the ground communication device and status feedback signals sent by the communication mechanism 10.

[0056] The transmission mechanism 60 serves as the signal transmission hub between the communication mechanism 10 and the ground communication equipment. Connecting the communication mechanism 10 at one end and the ground communication equipment at the other, it maintains stable signal transmission even as the communication mechanism rotates continuously with the adjustment mechanism. The transmission mechanism 60 employs a dual-link independent transmission design with a first channel and a second channel. The first channel is dedicated to transmitting communication signals between the ground communication equipment and the airborne communication target, ensuring low-loss transmission of high-speed communication data. The second channel is dedicated to transmitting control signals from the ground communication equipment and status signals fed back by the communication mechanism, enabling real-time, interference-free interaction between control commands and status information. This dual-channel independent transmission effectively reduces signal interference and transmission loss, avoids control delays or communication attenuation caused by rotation, and ensures the accurate, stable, and reliable operation of the entire system.

[0057] In one exemplary embodiment, such as Figure 2 As shown, a ground-to-air communication control method is provided, including steps 202 to 208. Wherein:

[0058] S202: During the process of ground communication equipment communicating with an airborne communication target through a communication mechanism, multi-dimensional data of the airborne communication target is collected; the multi-dimensional data includes three-dimensional coordinates, communication quality data, and attitude change data.

[0059] Optionally, in air-to-ground communication scenarios, airborne communication targets are typically in high-speed, continuous motion, and their position, signal quality, and flight attitude change constantly over time. Relying solely on single-dimensional data cannot accurately reflect the target's true state, easily leading to tracking errors, alignment delays, or link interruptions. Therefore, a multi-source data fusion approach is used to simultaneously acquire three-dimensional coordinate data, communication quality data, and attitude change data.

[0060] The three-dimensional coordinate data, including longitude, latitude, and altitude, is used to determine the current spatial position of the aerial communication target and serves as the basis for calculating the beam pointing angle. Communication quality data, including signal strength and Doppler frequency offset, reflects the actual transmission status of the current communication link and helps correct alignment deviations caused by propagation loss, interference, and obstruction. Attitude change data, including trends in flight speed, heading angle, and pitch angle, is used to determine the target's direction and speed of motion, providing a dynamic basis for predicting the target's position at the next moment. Through the synchronous acquisition and preprocessing of multi-dimensional data, a complete target state model can be constructed, effectively filtering out abnormal data such as environmental noise and interference fluctuations, improving the accuracy and robustness of subsequent calculations, and laying a data foundation for high-precision dynamic tracking.

[0061] S204: Based on the installation location coordinates and multi-dimensional data of the communication mechanism, obtain the reference communication angle at the current moment and the predicted communication angle at the next moment.

[0062] Optionally, based on the fixed installation coordinates of the communication mechanism and combined with the collected multi-dimensional data, the reference communication angle at the current moment and the predicted communication angle at the next moment are calculated respectively, forming a dual-angle control system of "current alignment and future prediction" to solve the problem of tracking lag in high-speed moving targets. Specifically, using the installation coordinates of the communication mechanism as a reference point and combined with the current three-dimensional coordinates of the aerial communication target, the azimuth and elevation angles that make the beam center of the communication mechanism accurately point to the target are calculated through spatial geometric relationships, spherical trigonometry, or coordinate system transformation methods. This angle is the reference communication angle. The reference communication angle represents the theoretical position that the communication mechanism should point to at the current moment, and is used to achieve basic alignment with the target.

[0063] Based on this, and using the collected attitude change data, including flight speed, rate of change of heading, acceleration trend, and radial velocity reflected by Doppler frequency shift, a motion prediction algorithm extrapolates the target's spatial position shortly afterward to obtain the estimated three-dimensional coordinates of the target at the next moment. Using these coordinates, the corresponding azimuth and pitch angles are calculated to form the predicted communication angle. The purpose of the predicted communication angle is to anticipate the target's future position, avoiding tracking delays caused by the communication mechanism merely following the current position. By simultaneously acquiring the reference communication angle and the predicted communication angle, both the accuracy of the current alignment and the ability to anticipate the target's motion trend are ensured. This transforms beam control from passive following to active prediction, significantly improving the stability and accuracy of dynamic tracking.

[0064] S206: Generate lead adjustment instructions based on the reference communication angle and the predicted communication angle.

[0065] Optionally, in high-speed air-to-ground communication scenarios, aerial targets move rapidly and their positions change drastically. If beam pointing is controlled solely based on the reference communication angle, the rotation of the communication mechanism will experience mechanical delays and response lags, causing the beam to consistently lag behind the target's actual position, leading to signal attenuation, tracking loss, or even communication interruption. To eliminate this problem, the deviation between the reference and predicted communication angles in both azimuth and elevation dimensions is first calculated. This deviation is the tracking lead. The tracking lead reflects the additional angle the communication mechanism needs to rotate to achieve beam pointing ahead of the target's future position. Then, this lead is converted into a control command that meets the driving requirements of the adjustment mechanism, namely the lead adjustment command. This command contains specific parameters such as rotation direction, rotation angle, and rotation speed, enabling precise driving of the first and second adjustment components to complete the corresponding actions. By generating and issuing the lead adjustment command, an effective conversion from data calculation to mechanical control is achieved, allowing the beam to actively point ahead.

[0066] S208: The communication angle of the communication mechanism is adjusted by driving the adjustment mechanism through the lead adjustment command, and the beamwidth of the communication mechanism is adjusted according to the relative distance between the communication mechanism and the air communication object; the communication angle includes azimuth and pitch angle.

[0067] Optionally, the control mechanism interprets the lead adjustment command into drive signals for the azimuth and pitch axes, respectively controlling the first and second adjustment components to rotate in specified directions, angles, and speeds. This drives the communication mechanism to adjust from the current angle to the predicted angle, ensuring the beam center points ahead of the target's next position, thus offsetting tracking errors caused by mechanical delay and motion. Simultaneously with angle adjustment, the relative distance between the communication mechanism and the airborne communication target is calculated in real time, and the beamwidth is adaptively adjusted based on the distance. For example, when the distance is far, the beamwidth is narrowed to increase antenna gain, enhance long-distance signal transmission capabilities, and ensure link strength; when the distance is close, the beamwidth is appropriately widened to expand signal coverage, improve target acquisition capabilities, and prevent beam deviation due to small attitude changes. The adjustment of the communication angle and the beamwidth are synchronized and coordinated to form a complete dynamic tracking control. The entire process operates continuously in a closed-loop state. The angle encoder inside the adjustment mechanism provides real-time feedback of the actual rotation angle, comparing and correcting it with the target angle to ensure alignment accuracy meets preset requirements.

[0068] In the aforementioned air-to-ground communication control method, during the communication process between the ground communication equipment and the air communication target via the communication mechanism, multi-dimensional data of the air communication target is collected. Based on the installation position coordinates of the communication mechanism and the multi-dimensional data, the reference communication angle at the current moment and the predicted communication angle at the next moment are obtained. Based on the reference communication angle and the predicted communication angle, a lead adjustment command is generated. The lead adjustment command drives the adjustment mechanism to adjust the communication angle of the communication mechanism. Based on the relative distance between the communication mechanism and the air communication target, the beamwidth of the communication mechanism is adjusted. This can reduce alignment delay, improve beam pointing accuracy, and reduce the probability of tracking loss, thereby effectively improving the stability of air-to-ground communication.

[0069] In an exemplary embodiment, the steps of obtaining the reference communication angle at the current moment and the predicted communication angle at the next moment based on the installation location coordinates and multi-dimensional data of the communication mechanism include: obtaining the coordinate difference between the installation location coordinates and the three-dimensional coordinates of the communication mechanism; obtaining the initial communication angle based on the coordinate difference; correcting the initial communication angle based on communication quality data to obtain the reference communication angle at the current moment; the communication quality data includes signal strength and Doppler frequency offset data; obtaining the predicted position coordinates of the airborne communication object at the next moment based on attitude change data; and obtaining the predicted communication angle at the next moment based on the coordinate difference between the installation location coordinates and the predicted position coordinates.

[0070] Optionally, the installation location coordinates of the communication mechanism and the three-dimensional coordinates of the airborne communication object are obtained. The coordinate differences in longitude, latitude, and altitude are calculated using spatial geometric relationships. Based on these coordinate differences, the initial azimuth and elevation angles of the communication mechanism's beam pointing towards the airborne communication object are calculated, i.e., the initial communication angle. This angle provides the basic geometric direction for beam alignment. Subsequently, the initial communication angle is corrected in real time using communication quality data (including signal strength and Doppler frequency offset data). Signal strength reflects link propagation loss and beam deviation, while Doppler frequency offset data reflects the radial velocity and movement trend of the airborne communication object relative to the ground. By compensating and correcting the initial communication angle using these two factors, alignment deviations caused by environmental interference, propagation delay, coordinate errors, and other factors can be eliminated, thus obtaining a precise and reliable reference communication angle for the current moment.

[0071] Furthermore, based on the attitude change data of the airborne communication target (including trends in flight speed, heading angle, and pitch angle), the predicted position coordinates at the next moment are calculated by extrapolation using a motion prediction model, enabling advance prediction of the target's trajectory. Using the installation position coordinates of the communication mechanism as a reference, the new coordinate difference between it and the predicted position coordinates is calculated. Through the same spatial geometric solution method, the azimuth and pitch angles of the corresponding predicted position are obtained, i.e., the predicted communication angle at the next moment, providing a basis for lead adjustment and advanced tracking.

[0072] In this embodiment, by obtaining the reference communication angle at the current moment and the predicted communication angle at the next moment based on the installation location coordinates and multi-dimensional data of the communication mechanism, the basic direction of the beam can be quickly determined, ensuring the real-time alignment. At the same time, it can compensate for the tracking lag caused by high-speed movement in advance, avoid beam tracking delay, loss of lock and signal interruption, and improve the stability and reliability of the air-to-ground communication link.

[0073] In an exemplary embodiment, the method further includes: acquiring link quality data; the link quality data includes reference signal received power, signal-to-interference-plus-noise ratio, and bit error rate; if the link quality data does not meet the signal requirements, generating an angle fine-tuning command based on the current communication angle and the link quality data; driving the adjustment mechanism to adjust the communication angle of the communication mechanism through the angle fine-tuning command, and adjusting the beamwidth of the communication mechanism based on the current relative distance.

[0074] Optionally, the monitoring agency continuously acquires link quality data of the communication connection between ground communication equipment and airborne communication targets, including three core indicators: reference signal received power, signal-to-interference-plus-noise ratio (SIR), and bit error rate (BER). After acquiring the link quality data, it compares it in real time with preset signal requirements to determine whether the current communication link is in a stable and reliable working state. When the reference signal received power is too low, the SIR is insufficient, or the BER exceeds the limit, it indicates that the communication agency's beam has slightly deviated, channel attenuation has intensified, or tracking accuracy has decreased. If not corrected in time, this will further lead to communication quality deterioration or even link interruption. At this time, based on the current communication angle and abnormal link quality data, a high-precision angle fine-tuning command is generated. This command aims for small-range, high-response, and stable adjustment to specifically compensate for beam pointing errors. The adjustment mechanism is driven by the angle fine-tuning command to make slight rotations in the azimuth and pitch angles, and the beam pointing of the communication mechanism is corrected in real time. At the same time, the beam width is adaptively optimized by combining the current relative distance between the communication mechanism and the air communication object. The beam is appropriately narrowed at long distances to improve gain, and the beam is appropriately widened at short distances to enhance the acquisition range and anti-disturbance capability, so that the beam can quickly return to the optimal alignment state, thereby restoring the link quality to the level that meets the preset requirements.

[0075] In this embodiment, by acquiring link quality data, if the link quality data does not meet the signal requirements, an angle fine-tuning command is generated based on the current communication angle and the link quality data. The angle fine-tuning command drives the adjustment mechanism to adjust the communication angle of the communication mechanism, and the beamwidth of the communication mechanism is adjusted according to the current relative distance. This enables a comprehensive and accurate assessment of the communication status and improves the reliability of the air-to-ground communication system.

[0076] In an exemplary embodiment, the method further includes: when there are multiple airborne communication objects within the communication range of the communication mechanism, obtaining the position priority of each airborne communication object; determining the current airborne communication object corresponding to the current communication cycle based on the position priority; and adjusting the communication angle and beamwidth of the communication mechanism based on the multi-dimensional data of the current airborne communication object.

[0077] Optionally, when multiple airborne communication objects are detected simultaneously within the effective communication range of the communication agency, each airborne communication object is assigned a corresponding positional priority based on its real-time spatial location, distance, heading trend, and loiter time. This priority is used to distinguish the urgency of access for multiple targets and the weight of communication resource allocation. Using a preset communication cycle as the time unit, and following the sorting rule from high to low positional priority, the airborne communication object requiring priority service is selected within the current communication cycle as the current airborne communication object. After determining the current service target, the control agency immediately retrieves the multi-dimensional data corresponding to the target, including three-dimensional coordinates, communication quality, attitude changes, etc. According to the single-target tracking logic, the azimuth and pitch angles of the communication agency are calculated and adjusted in real time. Simultaneously, the beamwidth is adaptively adjusted according to the target distance to ensure that the beam is accurately aligned with the current airborne communication object within the current communication cycle, completing signal transmission and reception and data interaction. When the next communication cycle arrives, the priority of each target location is reassessed, and the current service target is switched or maintained. This process is repeated to achieve time-sharing multiplexing, polling alignment, and concurrent communication of multiple targets, thus completing continuous coverage of multiple aerial objects without adding hardware.

[0078] In this embodiment, when there are multiple airborne communication objects within the communication range of the communication mechanism, the position priority of each airborne communication object is obtained. Based on the position priority, the current airborne communication object corresponding to the current communication cycle is determined. Based on the multi-dimensional data of the current airborne communication object, the communication angle and beamwidth of the communication mechanism are adjusted. This can improve the utilization efficiency and airspace coverage of ground communication equipment, and ensure the alignment accuracy and link stability of the air-to-ground communication system.

[0079] In one exemplary embodiment, such as Figure 3 As shown, a ground-to-air communication control method is provided, which includes the following steps:

[0080] (1) Multidimensional data acquisition: During the process of ground communication equipment communicating with the air communication object through the communication mechanism, multidimensional data of the air communication object is acquired; multidimensional data includes three-dimensional coordinates, communication quality data and attitude change data.

[0081] (2) Fusion analysis and alignment angle calculation: Obtain the coordinate difference between the installation position coordinates and the three-dimensional coordinates of the communication mechanism, and obtain the initial communication angle based on the coordinate difference; correct the initial communication angle based on the communication quality data to obtain the reference communication angle at the current moment; the communication quality data includes signal strength and Doppler frequency offset data; obtain the predicted position coordinates of the air communication object at the next moment based on the attitude change data; obtain the predicted communication angle at the next moment based on the coordinate difference between the installation position coordinates and the predicted position coordinates.

[0082] (3) Beam dynamics and alignment attitude adjustment: Based on the reference communication angle and the predicted communication angle, a lead adjustment command is generated. The lead adjustment command drives the adjustment mechanism to adjust the communication angle of the communication mechanism, and adjusts the beamwidth of the communication mechanism according to the relative distance between the communication mechanism and the air communication object; the communication angle includes azimuth and pitch angle.

[0083] (4) Communication link monitoring and real-time correction: acquire link quality data; the link quality data includes reference signal received power, signal-to-interference-plus-noise ratio and bit error rate; if the link quality data does not meet the signal requirements, generate an angle fine-tuning command based on the current communication angle and the link quality data; drive the adjustment mechanism to adjust the communication angle of the communication mechanism through the angle fine-tuning command, and adjust the beamwidth of the communication mechanism based on the current relative distance.

[0084] (5) Concurrent alignment of multiple communication objects: When there are multiple air communication objects within the communication range of the communication agency, the position priority of each air communication object is obtained; based on the position priority, the current air communication object corresponding to the current communication cycle is determined; based on the multi-dimensional data of the current air communication object, the communication angle and beamwidth of the communication agency are adjusted.

[0085] For example, the method is applied to a large-scale beam dynamic tracking scenario of a single civil aircraft. The communication equipment is a ground base station, the adjustment mechanism adopts a dual-axis servo turntable, the communication mechanism adopts a high-gain ground antenna, and the transmission mechanism adopts a dual-channel rotary joint.

[0086] During system initialization, the dual-axis servo turntable is reset to azimuth and elevation angles of 0°, and the high-gain ground antenna beamwidth is adjusted to 1°. Preset parameters are configured: alignment accuracy ±0.1°, Reference Signal Received Power (RSRP) threshold 110dBm, Signal-to-Interference-plus-Noise Ratio (SINR) threshold 15dB, and Bit Error Rate (BER) threshold 10. -6 The initial angular velocity of the turntable is 5° / s, and the GPS / BeiDou sampling frequency of the sensing mechanism is 10Hz. The ground base station establishes an initial communication connection with the aircraft to complete the identification process.

[0087] The sensing mechanism collects real-time data such as the aircraft's three-dimensional coordinates (e.g., longitude 116.3°, latitude 39.9°, altitude 7500m), RSRP (-85dBm), Doppler shift (2kHz), flight speed (700km / h), and heading angle (90°). After filtering out abnormal data, the data is transmitted to the control mechanism.

[0088] The control mechanism, combining the ground antenna installation coordinates (longitude 116.2°, latitude 39.9°, altitude 50m), calculates the initial alignment angle (azimuth 8.5°, elevation 40.5°) through spatial geometry. Then, by combining RSRP and Doppler frequency shift data for correction, the theoretical alignment angle (azimuth 8.4°, elevation 40.4°) is obtained. At the same time, based on the aircraft's flight speed and heading angle, the three-dimensional coordinates of the aircraft are predicted 100ms later, and the predicted alignment angle (azimuth 8.6°, elevation 40.6°) is calculated to generate a lead adjustment command.

[0089] The control mechanism sends drive commands to control the dual-axis servo turntable to rotate at an angular velocity of 5° / s to adjust to the theoretical alignment angle. At the same time, it controls the high-gain ground antenna to adjust the beamwidth to 0.8° (the aircraft is about 11km away from the ground antenna). The angle encoder configured in the sensing mechanism collects the actual rotation angle (azimuth angle 8.42°, pitch angle 40.6°) and feeds it back to the control mechanism for fine-tuning to ensure that the alignment accuracy reaches ±0.1°, thus completing the precise beam alignment.

[0090] The monitoring agency collects real-time link quality data: RSRP = -100dBm, SINR = 18dB, Bit Error Rate = 5 × 10⁻ 7 All parameters meet the preset thresholds and maintain the current alignment attitude and beam parameters. When the aircraft suddenly turns (the heading angle becomes 100°), the sensing mechanism quickly collects the position change, and the control module immediately fine-tunes the turntable angle to an azimuth angle of 10.2° and a pitch angle of 42.1° to ensure that the beam is always aligned with the aircraft.

[0091] When the aircraft flies out of the airspace covered by the ground antenna (for example, when the distance exceeds 100km and the sensing mechanism fails to collect signal quality data for 5 consecutive seconds), the control mechanism sends a reset command, the dual-axis servo turntable resets to the reference position, the antenna beamwidth is restored to 1°, and the system enters standby mode.

[0092] In this embodiment, during the communication process between the ground communication equipment and the airborne communication object via the communication mechanism, multi-dimensional data of the airborne communication object is collected. Based on the installation position coordinates of the communication mechanism and the multi-dimensional data, the reference communication angle at the current moment and the predicted communication angle at the next moment are obtained. Based on the reference communication angle and the predicted communication angle, a lead adjustment command is generated. The lead adjustment command drives the adjustment mechanism to adjust the communication angle of the communication mechanism. Based on the relative distance between the communication mechanism and the airborne communication object, the beamwidth of the communication mechanism is adjusted. This can reduce alignment delay, improve beam pointing accuracy, and reduce the probability of tracking loss, thereby effectively improving the stability of ground-to-air communication.
