[0025] Method Embodiment

[0026] According to an embodiment of the present invention, an automatic satellite station tracking method is provided. Figure 1 is a flow chart of an automatic satellite station tracking method according to an embodiment of the present invention. Figure 1 As shown, the automatic satellite station tracking method according to an embodiment of the present invention specifically includes:

[0027] Step 101, determining a replacement satellite for a target satellite in the area, and obtaining satellite parameter information of the replacement satellite; wherein a satellite that is relatively easy to track within a certain range of the target satellite and / or a satellite with beacon information can be determined as the replacement satellite;

[0028] The satellite parameter information specifically includes at least one of the following: satellite latitude, frequency, and symbol rate.

[0029] Step 102, after the automatic satellite station is powered on, the satellite parameter information of the replacement satellite is input into the automatic satellite station, and the replacement satellite is automatically tracked through the antenna; specifically, the following processing is included: setting the frequency of the replacement satellite to the automatic satellite station, using the longitude and local geographical location information of the replacement satellite to calculate the theoretical azimuth, theoretical pitch, and theoretical polarization, and moving the azimuth, pitch, and polarization to the theoretical position, searching for and locking the replacement satellite.

[0030] Step 103, according to the positional relationship between the replacement satellite and the target satellite, after the automatic satellite station is locked, directly point to the target satellite. Specifically, the following processing is included:

[0031] Calculating the theoretical azimuth, theoretical pitch, and theoretical polarization of the target satellite using the longitude and local geographic location information of the target satellite, and moving the polarization to the theoretical polarization position of the target satellite;

[0032] Calculating the theoretical azimuth difference between the substitute satellite and the target satellite, and controlling the motor to move the difference angle to the actual azimuth position of the target satellite;

[0033] The theoretical pitch difference between the substitute satellite and the target satellite is calculated, and the motor movement difference angle is controlled to move to the actual pitch position of the target satellite to complete the tracking of the target satellite.

[0034] The above technical solution of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0035] like Figure 2 As shown, in order to achieve satellite tracking in the above-mentioned areas, satellites and abnormal situations, first determine the latitude, frequency, symbol rate and other information of the satellite that is relatively easy to track near the target satellite in the area, and then after the automatic satellite station is powered on, input the parameters of the satellite that is easy to track near the target satellite into the satellite station, and the antenna automatically tracks the easy-to-track satellite near the target satellite, and then, based on the positional relationship between the two satellites, after the satellite station is locked, directly point to the target satellite. Figure 2 It can be seen that satellite 2 is the target satellite, and satellite 1 is a satellite that is easier to track near the target satellite or has beacon information. In actual tracking, satellite 1 can be tracked first, and after the satellite is locked, the target satellite 2 can be directly pointed to based on the relationship between the two satellites.

[0036] like Figure 3 As shown, the tracking strategy implementation method and strategy are as follows:

[0037] 1) Set the satellite 1 frequency to the satellite station;

[0038] 2) Calculate the theoretical azimuth, theoretical elevation, and theoretical polarization using the longitude of satellite 1 and the local geographic location information, and then move the azimuth, elevation, and polarization to the theoretical position;

[0039] 3) Search for satellite 1;

[0040] 4) Lock on satellite 1;

[0041] 5) Calculate the theoretical azimuth, theoretical pitch, and theoretical polarization of Satellite 2 using the longitude of Satellite 2 (target satellite) and local geographic location information;

[0042] 6) Polarization moves to the theoretical polarization position of satellite 2;

[0043] 7) Calculate the theoretical azimuth difference between satellite 1 and satellite 2, and control the motor movement difference angle to move to the actual azimuth position of satellite 2 (target satellite);

[0044] 8) Calculate the theoretical pitch difference between satellite 1 and satellite 2, and control the motor movement difference angle to move to the actual pitch position of satellite 2 (target satellite);

[0045] 9) Target star tracking is completed.

[0046] To sum up, the above technical scheme of the embodiment of the present invention can be used in satellite communication control systems; it supports tracking without beacons and tracking with weak satellite coverage; it has strong scalability and can be applied to vehicle-mounted static satellite antennas, vehicle-mounted moving antennas and ship-mounted antennas; it is simple to implement, does not increase any cost compared to traditional satellite antennas, and is suitable for large-scale promotion.
