[0024] The raw materials and instruments used in the embodiments are not specifically limited in source and can be purchased on the market or prepared according to conventional methods well known to those skilled in the art.

[0025] In view of the defects in the prior art, the present disclosure provides a remote sensing satellite and high-orbit communication satellite communication method, which is applied to a remote sensing satellite. Figure 1 A flow 100 of one embodiment of a remote sensing satellite and high-orbit communication satellite communication method is shown, and the remote sensing satellite and high-orbit communication satellite communication method comprises the following steps:

[0026] In step 101, at least one communication period of a remote sensing satellite and a high-orbit communication satellite is acquired.

[0027] In this embodiment, the communication period is a time period in which the remote sensing satellite and the high-orbit communication satellite can establish a communication link. The communication period is specifically obtained by: determining at least one visible period of the remote sensing satellite and the high-orbit communication satellite, for each visible period of the at least one visible period, based on the positions of the remote sensing satellite and the high-orbit communication satellite and the attitude of the remote sensing satellite in the sunlit region or the earth shadow region, calculating the antenna pointing angles of the remote sensing satellite and the high-orbit communication satellite, and determining that the remote sensing satellite and the high-orbit communication satellite can establish a communication link when the antenna pointing angles are within an angle constraint range and there is no earth blockage, and that the visible period of the remote sensing satellite corresponding to the communication period is the communication period. The angle constraint range is an angle range of the antenna azimuth angle and the elevation angle.

[0028] In this embodiment, the visible period is a time period in which the remote sensing satellite and the high-orbit communication satellite can establish a communication link. The time period can be a time period selected from a visible period calculation interval of the remote sensing satellite. Specifically, a service time period in which the remote sensing satellite can perform space measurement and control services is determined, and a visible period calculation interval in which the visible period can be calculated is determined based on the service time period.

[0029] Optionally, the step 101 includes: obtaining at least one visible period, determining whether there is a visible period in the at least one visible period that can be used for data transmission such as remote sensing, remote control, and image data transmission between the remote sensing satellite and the high-orbit communication satellite according to the remote sensing satellite data transmission working period on the ground segment of the remote sensing satellite and the available constraint conditions of the remote sensing, remote control antenna azimuth angle and elevation angle of the high-orbit communication satellite, and determining the visible period as the communication period if there is.

[0030] In step 102, at least one antenna azimuth angle and elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite are determined based on the at least one communication period.

[0031] In this embodiment, the at least one antenna azimuth angle and elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite are the antenna azimuth angle and elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite calculated in advance on the remote sensing satellite. Each communication period of the at least one communication period has a corresponding antenna azimuth angle and elevation angle.

[0032] In this embodiment, the at least one antenna azimuth angle and elevation angle are angles at different time periods. By comparing each communication period in the at least one communication period with the time of the at least one antenna azimuth angle and elevation angle, it can be determined that each communication period corresponds to which antenna azimuth angle and elevation angle.

[0033] In this embodiment, the communication period can be converted into the corresponding antenna azimuth and elevation angle by the deep learning model. Specifically, the deep learning model is obtained by classifying a large number of periods, antenna azimuths and elevations, and represents the corresponding relationship between the three.

[0034] Optionally, the antenna azimuth and elevation angle can also be obtained from the ground. Specifically, after determining the communication period, the antenna azimuth and elevation angle corresponding to the communication period are directly obtained from the ground station. Inter-satellite link establishment is a key technology of the relay satellite system and is the primary condition for establishing an inter-satellite transmission channel. When a user satellite needs to establish communication with a relay satellite, its antenna needs to capture and then track the relay satellite. The inter-satellite link establishment process of the relay system is briefly described as follows:

[0035] 1) The orbit motion data of the relay satellite and the user satellite within the predetermined service time is predicted by the orbit determination system according to the ephemeris table;

[0036] 2) The orbit prediction data of the relay satellite and the user satellite is injected into the on-board computer of the user satellite;

[0037] 3) The motion parameters of the relay satellite are converted into the user satellite coordinate system by considering the relative motion between the relay satellite and the user satellite;

[0038] 4) The on-board computer calculates the pointing error of the antenna according to the orbit prediction data, selects the control mode according to the error size, and sends the command to open-loop control the user satellite antenna to point to the relay satellite;

[0039] In summary, the user satellite antenna capture and tracking control system first guides the antenna to point to the relay satellite according to the orbit prediction program, then performs a small-angle scanning to capture the relay satellite, and gradually enters the automatic tracking state to track the relay satellite from the traction capture stage.

[0040] Step 103, generating antenna wave control codes at different times based on at least one antenna azimuth and elevation angle.

[0041] In this embodiment, the antenna wave control code is a core parameter used to control the pointing of the antenna beam in a phased array antenna system. It achieves precise scanning and pointing of the beam in space by adjusting the phase and amplitude of each radiating element in the antenna array. The generation process of the wave control code involves multiple steps, including parameter input, phase calculation, quantization processing, and code value generation. The parameter input includes the use of rectangular grid or triangular grid layout to determine the arrangement of the antenna elements. The target pointing angle parameters include the azimuth and elevation angles, which need to be converted into electromagnetic wave propagation vectors. Phase calculation: according to the target pointing angle, the phase delay of each element relative to the reference element is calculated. Quantization processing: the continuous phase value obtained by calculation is quantized into digital wave control code. Code value generation: the final generated wave control code is used to control the phase and amplitude of each radiating element in the antenna array, thereby achieving precise pointing of the beam.

[0042] The antenna wave control code is used to control the scanning and pointing of the beam, improving the detection and tracking capability of the target. In satellite communication, the wave control code is used to accurately track the satellite, ensuring stable transmission of the signal.

[0043] Step 104, based on the antenna wave control code, generate antenna beams pointing to high-orbit communication satellites at different time points, and send satellite communication signals to the high-orbit communication satellites through the antenna beams, so that the high-orbit communication satellites receive the satellite communication signals after searching and locking the antenna beams.

[0044] In this embodiment, the antenna beam refers to the main lobe of the satellite antenna radiation pattern, which concentrates most of the radiation energy. The illuminated area of the beam on the Earth is the coverage area of the antenna. The satellite antenna beam transmits satellite communication signals through electromagnetic waves, realizing information exchange between the satellite and the high-orbit communication satellite.

[0045] In this embodiment, the remote sensing satellite ground segment can pre-acquire the visible period calculation interval of the remote sensing satellite and the high-orbit communication satellite, and through the remote sensing satellite ground segment software, the communication period (the start and end times are slightly different when calculating the communication period, and the remote sensing satellite orbit six numbers of the ground segment software are not the latest) in the visible period calculation interval can be calculated for the remote sensing satellite and the high-orbit communication satellite, and the communication period is sent to the high-orbit communication satellite ground segment. The high-orbit communication satellite ground segment sends the remote sensing satellite and high-orbit communication satellite communication period to the high-orbit communication satellite space segment through the satellite-ground link, and the high-orbit communication satellite receives the signal from the remote sensing satellite antenna in the specified area according to the communication period of the remote sensing satellite, searches and locks the antenna beam of the remote sensing satellite, and receives the satellite communication signal of the remote sensing satellite after locking the antenna beam.

[0046] The method for communication between the remote sensing satellite and the high-orbit communication satellite provided by the present disclosure can be used to carry out satellite calculation of the remote sensing satellite and the high-orbit communication satellite in a control envelope after the remote sensing satellite is instructed to start from the ground, and to form communication with the high-orbit communication satellite. The communication with the high-orbit communication satellite can maximize the satellite information acquisition and emergency instruction uploading of the remote sensing satellite during the non-ground station transit period, and improve the real-time response capability of the remote sensing satellite.

[0047] In some optional implementations of the present disclosure, the determination of the at least one antenna azimuth angle and the at least one antenna elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite based on the at least one communication period comprises: for each communication period in the at least one communication period, matching a table period corresponding to the communication period from a pre-set period-angle table; and in response to the matching success of the table period in the period-angle table and the communication period, taking the antenna azimuth angle and the antenna elevation angle corresponding to the table period as the antenna azimuth angle and the antenna elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite.

[0048] In the optional implementation, the period-angle table is a table recording the correspondence among the table period, the antenna azimuth angle and the antenna elevation angle. When a period is the same as or similar to a table period in the period-angle table (determination of matching success), the corresponding antenna azimuth angle and antenna elevation angle can be matched. When a period is not the same as or similar to any table period in the period-angle table, it is determined that the corresponding antenna azimuth angle and antenna elevation angle cannot be matched.

[0049] The method for determining the at least one antenna azimuth angle and the at least one antenna elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite provided by the optional implementation comprises: for each communication period in the at least one communication period, matching a table period corresponding to the communication period from a pre-set period-angle table; and in response to the matching success of the table period in the period-angle table and the communication period, taking the antenna azimuth angle and the antenna elevation angle corresponding to the table period as the antenna azimuth angle and the antenna elevation angle of the remote sensing satellite pointing to the high-orbit communication satellite. The antenna azimuth angle and the antenna elevation angle are obtained simply and conveniently, and the reliability and accuracy of the antenna azimuth angle and the antenna elevation angle are improved.

[0050] In some optional implementations of the present disclosure, the generation of the antenna wave control code at different time instants based on the at least one antenna azimuth angle and the at least one antenna elevation angle comprises: for each antenna azimuth angle and each antenna elevation angle in the at least one antenna azimuth angle and the at least one antenna elevation angle, matching a table angle corresponding to the antenna azimuth angle and the antenna elevation angle from a pre-set angle-wave code table; and in response to the matching success of the table angle in the angle-wave code table and the antenna azimuth angle and the antenna elevation angle, taking the antenna wave control code corresponding to the antenna azimuth angle and the antenna elevation angle as the antenna wave control code of the current communication period.

[0051] In the optional implementation, the angle-wave code table is a table recording the correspondence between table angles and antenna wave control codes, wherein the table angles are used to represent different antenna azimuth angles and elevation angles, and when the antenna azimuth angle and the elevation angle are both the same as the table angles in the angle-wave code table, the corresponding antenna wave control code can be matched and found. When at least one of the antenna azimuth angle and the elevation angle is different from the table angles in the angle-wave code table, it is determined that the corresponding antenna wave control code cannot be matched.

[0052] In the optional implementation, the time corresponding to the antenna wave control code can be generated through a communication period, for example, the antenna wave control codes at different times are time points randomly selected from the time points in the communication period corresponding to the antenna wave control code, or the middle time points selected from the communication period corresponding to the antenna wave control code.

[0053] The method for generating antenna wave control codes at different times provided in the optional implementation is simple and convenient to obtain the antenna wave control code and improve the reliability and accuracy of the antenna wave control code, by matching the table angle corresponding to each antenna azimuth angle and elevation angle from the pre-set angle-wave code table, and taking the antenna wave control code corresponding to the antenna azimuth angle and elevation angle as the antenna wave control code of the current communication period in response to the successful matching of the table angle in the angle-wave code table and the antenna azimuth angle and elevation angle.

[0054] The present disclosure provides another embodiment of a remote sensing satellite and high-orbit communication satellite communication method, which is applied to a high-orbit communication satellite. Figure 2 The flow 200 of another embodiment of the remote sensing satellite and high-orbit communication satellite communication method is shown, and the remote sensing satellite and high-orbit communication satellite communication method comprises the following steps:

[0055] In step 201, according to the time period available for the remote sensing satellite and the high-orbit communication satellite communication in the visible time period of the remote sensing satellite, the area range where the remote sensing satellite is located is scanned, and the antenna beam of the remote sensing satellite at the current time is searched and locked.

[0056] In this embodiment, the visible period is determined according to the overflight of the remote sensing satellite, and the time period in which the high-orbit communication satellite can carry out telemetry, remote control and data transmission services with the remote sensing satellite. The time period can be a time period selected from the visible period calculation interval obtained from the ground section of the remote sensing satellite, and is used for the communication time period of the remote sensing satellite and the high-orbit communication satellite. Specifically, the service time period in which the remote sensing satellite can carry out space measurement and control services is determined first, and the visible period calculation interval in which the visible period can be calculated is determined through the service time period. At least one visible period of the remote sensing satellite and the high-orbit communication satellite is determined, and for each visible period of the at least one visible period, the position of the remote sensing satellite and the high-orbit communication satellite and the attitude of the remote sensing satellite in the sunlit area or the earth shadow area are determined. The antenna pointing angle of the remote sensing satellite and the high-orbit communication satellite calculated based on the position of the remote sensing satellite and the high-orbit communication satellite and the attitude of the remote sensing satellite in the sunlit area or the earth shadow area is within the angle constraint range, and there is no earth blockage. It is considered that the remote sensing satellite and the high-orbit communication satellite can establish a communication link, and the visible period corresponding to the remote sensing satellite at this time is the communication period.

[0057] Alternatively, the visible period can also be obtained in the following way: in the overflight area of the remote sensing satellite, all working time periods of the remote sensing satellite are determined, the non-service time period in which telemetry, remote control, data transmission and other space measurement and control services are not carried out is removed from the working time period, and at least one visible period of the remote sensing satellite and the high-orbit communication satellite is obtained. Further, for each visible period of the at least one visible period, the position of the remote sensing satellite and the high-orbit communication satellite and the attitude of the remote sensing satellite in the sunlit area or the earth shadow area are determined. The antenna pointing angle of the remote sensing satellite and the high-orbit communication satellite calculated based on the position of the remote sensing satellite and the high-orbit communication satellite and the attitude of the remote sensing satellite in the sunlit area or the earth shadow area is within the angle constraint range, and there is no earth blockage. It is considered that the remote sensing satellite and the high-orbit communication satellite can establish a communication link, and the visible period corresponding to the remote sensing satellite at this time is the communication period.

[0058] In this embodiment, the step 201 comprises: the high-orbit communication satellite determines the approximate azimuth and elevation information of the remote sensing satellite, and determines and points the measurement and control antenna to the area range where the remote sensing satellite may appear according to the approximate azimuth and elevation information. Specifically, the mechanical rotating antenna or the beam electric scanning function of the antenna is usually used to search within a certain angle (elevation angle, azimuth angle) range to achieve the purpose of scanning the area range where the remote sensing satellite is located, so as to find the approximate direction of the remote sensing satellite and the high-orbit communication satellite antenna beam.

[0059] Step 202, the satellite communication signal transmitted by the remote sensing satellite is captured through the antenna beam.

[0060] In this embodiment, the antenna beam is a key component of signal transmission in satellite communication. The antenna of the remote sensing satellite concentrates the satellite communication signal in a specific direction through the antenna beam, ensuring that the satellite communication signal can be accurately transmitted to the target receiver of the high-orbit communication satellite. This directional transmission reduces signal interference and improves transmission quality.

[0061] In this embodiment, step 202 includes: acquiring the initial signal transmitted by the remote sensing satellite; detecting whether the signal strength of the initial signal is greater than the strength threshold; and in response to detecting that the signal strength of the initial signal is greater than the strength threshold, regarding the initial signal as the satellite communication signal. The strength threshold can be determined based on development requirements. When the received signal strength exceeds the strength threshold, it is considered that the satellite communication signal of the remote sensing satellite communicating with the high-orbit communication satellite is detected.

[0062] In this embodiment, the satellite communication signal can be a signal obtained by real-time tracking and processing of the signal transmitted by the remote sensing satellite. As described above, step 202 includes: continuously receiving the signal transmitted by the remote sensing satellite and performing real-time processing on the signal. Alternatively, the satellite communication signal can also be the signal directly acquired by the remote sensing satellite.

[0063] Step 203: based on the satellite communication signal, calculating the angle to be adjusted of the TT&C antenna.

[0064] In this embodiment, the angle to be adjusted is the angle deviation of the remote sensing satellite relative to the TT&C antenna of the high-orbit communication satellite, i.e., the deviation of the azimuth angle and the elevation angle. The TT&C antenna is the antenna used by the high-orbit communication satellite to communicate with the remote sensing satellite. By calculating the angle to be adjusted, it can be determined how to adjust the TT&C antenna.

[0065] In this embodiment, step 203 includes: determining the phase difference and amplitude difference of the satellite communication signal in different antenna elements or receiving channels of the TT&C antenna, and performing angle conversion on the phase difference and amplitude difference of all antenna elements or receiving channels to obtain the angle to be adjusted.

[0066] Step 204: based on the angle to be adjusted, adjusting the position of the mechanical rotation of the TT&C antenna or the beam pointing.

[0067] In this embodiment, the pointing of the TT&C antenna of the high-orbit communication satellite is calibrated according to the calculated angle to be adjusted, so that the position of the mechanical rotation of the TT&C antenna or the beam pointing is accurately aligned with the remote sensing satellite.

[0068] The method for communication between a remote sensing satellite and a high-orbit communication satellite provided by the present disclosure comprises: scanning a range of an area where the remote sensing satellite is located according to a time period available for communication between the remote sensing satellite and the high-orbit communication satellite in a visible time period of the remote sensing satellite, searching for and locking an antenna beam of the remote sensing satellite at a current time; capturing a satellite communication signal transmitted by the remote sensing satellite through the antenna beam; calculating an angle to be adjusted of a TT&C antenna based on the satellite communication signal; and adjusting a position of mechanical rotation or a beam pointing direction of the TT&C antenna based on the angle to be adjusted. Thus, the range of the area where the remote sensing satellite is located is scanned in the visible time period of the remote sensing satellite, so that the remote sensing satellite can be located in time and area; the angle to be adjusted of the TT&C antenna is calculated based on the satellite communication signal, and the position of mechanical rotation or the beam pointing direction of the TT&C antenna is adjusted, so that the high-orbit communication satellite can point to the remote sensing satellite in real time, and the reliability and accuracy of communication between the remote sensing satellite and the high-orbit communication satellite are improved.

[0069] Optionally, the method further comprises: in response to the satellite communication signal representing that a task is completed or the angle to be adjusted exceeds a tracking angle range of the TT&C antenna, controlling the TT&C antenna to stop working. When the remote sensing satellite completes a task or exceeds the tracking angle range of the TT&C antenna, the tracking system determines that the remote sensing satellite has left the tracking, and stops the tracking operation on the remote sensing satellite. At this time, the TT&C antenna stops rotating (or the electrically scanned beam stops scanning), and the tracking device enters a standby state.

[0070] Optionally, the method further comprises: determining relevant information of the remote sensing satellite based on the satellite communication signal, wherein the relevant information is data related to telemetry and data transmission, and the remote sensing satellite is controlled based on the relevant information. In this embodiment, the high-orbit communication satellite tracks the signal transmitted by the antenna of the remote sensing satellite, and when the signal is locked, the relevant information (telemetry and data transmission data) of the remote sensing satellite is transmitted to the high-orbit communication satellite, so that data is returned. After receiving the telemetry information of the remote sensing satellite "remote control link locking", the high-orbit satellite can send remote control instructions through the remote control link, so as to implement uploading of instructions and tasks such as telemetry, remote control, data transmission data and remote sensing tasks of the remote sensing satellite.

[0071] In some optional implementations of the present disclosure, the scanning of the range of the area where the remote sensing satellite is located, the searching for and locking of the antenna beam of the remote sensing satellite at the current time comprise: searching for a preset angle range where the remote sensing satellite is located by using a mechanically rotating antenna or a beam electrically scanning function of the antenna, determining a beam direction of the antenna beam of the remote sensing satellite at the current time; receiving the satellite communication signal transmitted by the remote sensing satellite in the beam direction; and in response to the signal strength of the satellite communication signal being greater than a set strength threshold and the satellite communication signal satisfying a signal feature condition, determining that the antenna beam of the remote sensing satellite at the current time is searched for, and locking the antenna beam of the remote sensing satellite at the current time.

[0072] In the optional implementation, the preset angle range can be a predicted range determined by judging and determining the direction and position of the remote sensing satellite in advance, and the angle range can be determined by a model or an algorithm. The beam direction of the antenna beam can be determined through the preset angle range.

[0073] In the optional implementation, the intensity threshold can be determined based on the opening requirement, and the signal feature condition includes that the signal-to-noise ratio is greater than a signal-to-noise ratio threshold and the bit error rate is less than a bit error rate threshold. The signal feature condition of the satellite communication signal can be different based on different forms of the satellite communication signal.

[0074] The method for searching and locking the antenna beam of the remote sensing satellite at the current time provided by the optional implementation first searches a preset angle range to determine the beam direction of the antenna beam, and receives the satellite communication signal in the beam direction. The signal strength of the satellite communication signal and the signal feature condition of the satellite communication signal are used to improve the accuracy and reliability of the antenna beam locking.

[0075] In some optional implementations of the present disclosure, the above calculating the angle to be adjusted of the measurement and control antenna based on the satellite communication signal includes: performing signal processing on the satellite communication signal to obtain processing information; extracting state information in the processing information, and calculating quality information of the satellite communication signal; detecting whether the satellite communication signal is an abnormal signal based on the state information and the quality information; and in response to detecting that the satellite communication signal is not an abnormal signal, calculating the angle to be adjusted of the measurement and control antenna based on the state information and the current pointing direction of the measurement and control antenna.

[0076] In the optional implementation, the above signal processing on the satellite communication signal includes: analyzing and processing the satellite communication signal by using a signal processing algorithm to determine signal feature conditions such as frequency and phase of the satellite communication signal, and taking the signal feature conditions as the processing information. The processing information is obtained to realize preliminary acquisition of the signal transmitted by the remote sensing satellite.

[0077] In the optional implementation, the above extracting state information in the processing information and calculating quality information of the satellite communication signal includes: extracting state information such as position, velocity, and attitude in the processing information; and calculating quality information such as signal-to-noise ratio and bit error rate of the processing information.

[0078] In the optional implementation, the above detecting whether the satellite communication signal is an abnormal signal based on the state information and the quality information includes: detecting whether the state information conforms to a preset state and whether the quality information conforms to a preset quality condition, and in response to detecting that the state information conforms to the preset state and the quality information conforms to the preset quality condition, determining that the satellite communication signal is not an abnormal signal; otherwise, determining that the satellite communication signal is an abnormal signal.

[0079] In this optional implementation, the above calculation of the angle to be adjusted of the TT&C antenna based on the state information and the current pointing direction of the TT&C antenna includes: calculating in real time the angle to be adjusted of the TT&C antenna according to the state information of the remote sensing satellite and the current pointing direction of the TT&C antenna of the high-orbit communication satellite and the remote sensing satellite.

[0080] In this optional implementation, the angle can be calculated by a tracking algorithm. The tracking algorithm is a core function of a tracking receiver, which is used to track the changes of parameters such as frequency, phase and amplitude of a target signal to ensure that the signal can be received stably all the time. Common tracking algorithms include phase-locked loop (PLL) and frequency-locked loop (FLL).

[0081] Phase-locked loop (PLL): mainly used for tracking the phase changes of a signal. It compares the phase of the received signal with the phase of the locally generated reference signal, generates a phase error signal, and then filters and adjusts the error signal through a loop filter to control the frequency and phase of the voltage-controlled oscillator, so that it remains synchronized with the phase of the received signal. This can always keep accurate tracking of the signal in the presence of phase jitter or Doppler shift.

[0082] Frequency-locked loop (FLL): used for tracking the frequency changes of a signal. It monitors the difference between the frequency of the received signal and the local reference frequency, generates a frequency error signal, and adjusts the frequency of the local oscillator through a corresponding control mechanism to keep them consistent. Frequency-locked loop is very effective in dealing with signals with large frequency drift, for example, in satellite communication, due to the movement of the satellite and the Doppler effect, the frequency of the received signal will change, and the frequency-locked loop can track this frequency change in real time to ensure that the receiver can correctly demodulate the signal.

[0083] Feedback control: according to the error information obtained by the tracking algorithm, the control signal is generated and fed back to the relevant modules in the front end, such as voltage-controlled oscillator, gain control circuit, etc., to adjust the parameters of the receiver, so as to realize accurate tracking and stable reception of the signal. For example, due to the deviation of the antenna pointing direction, the signal amplitude decreases, and the high-orbit communication satellite will calculate the direction and angle that the communication and measurement and control antenna needs to adjust according to the comprehensive information of frequency, phase and amplitude, and accurately adjust the pointing direction of the communication and measurement and control antenna through the antenna control mechanism (or beam control unit), so that the high-orbit communication satellite communication and measurement and control antenna beam is re-aligned with the remote sensing satellite, so as to restore the strength and stability of the signal and maintain a good communication link. For example, the output frequency of the voltage-controlled oscillator (VCO) is proportional to the input control voltage. When the error signal is positive, the frequency of the VCO will increase; when the error signal is negative, the frequency of the VCO will decrease. By adjusting the angle of the high-orbit communication satellite communication and measurement and control antenna beam, the output frequency of the VCO will be continuously adjusted, so that it gradually approaches the frequency of the user satellite signal, and the phase will also be gradually locked.

[0084] The method for calculating the angle to be adjusted provided by the optional implementation provides signal processing for the satellite communication signal to obtain processing information; state information in the processing information is extracted, and quality information of the satellite communication signal is calculated; based on the state information and the quality information, it is detected whether the satellite communication signal is an abnormal signal; in response to detecting that the satellite communication signal is not an abnormal signal, the state information and the current pointing direction of the measurement and control antenna are used to calculate the angle to be adjusted of the measurement and control antenna. The angle to be adjusted is calculated again when the satellite communication signal is not an abnormal signal, which improves the reliability of the angle to be adjusted.

[0085] Optionally, the above-mentioned calculation of the angle to be adjusted of the measurement and control antenna based on the satellite communication signal further comprises: real-time tracking of the satellite communication signal, and continuously correcting the angle to be adjusted in the process of tracking the satellite signal, so as to maintain the accurate pointing of the remote sensing satellite measurement and control antenna to the remote sensing satellite.

[0086] Due to the change of the motion state of the remote sensing satellite and the influence of external environmental factors (such as electromagnetic interference, atmospheric refraction, etc.), the tracking system needs to have the ability of self-adaptive adjustment. Optionally, the above-mentioned method further comprises: obtaining the change state of the quality information, automatically adjusting the tracking bandwidth, gain and other parameters based on the change state to optimize the tracking performance; according to the acceleration, angular velocity and other changes of the remote sensing satellite motion, the parameters of the tracking algorithm are adjusted in time to ensure the stability and accuracy of the tracking.
