The present invention discloses a dynamic satellite alignment control method and a device. The method comprises a step of calculating the pitch pointing of an antenna through a low-accuracy inertial navigation solution, obtaining the pitch pointing angle of the antenna, and adjusting the antenna to the position corresponding to the antenna pointing angle, a step of building a space position ring according to the spatial angle rate of a gyroscope, controlling an azimuth direction and a pitch angle, obtaining the beacon value corresponding to each position in a circle that an antenna is rotated, and determining a maximum beacon value in the beacon value corresponding to each position, a step of with the position corresponding to the maximum beacon value as a center, according to the intervention step length of a first ratio, obtaining the beacon value corresponding to each position, and selecting the specified position corresponding to a beacon value of a strongest signal, and a step of adjusting the antenna to the specified position. With a azimuth and a pitch gyroscope as a key device, a space position ring is constructed, the closed-loop scanning of azimuth degree of freedom is carried out, the small-scale accurate scanning is carried out, and the functions of dynamic alignment and tracking of a satellite are completed.
Description
technical field [0001] The present application relates to the field of satellite technology, in particular to a method and device for dynamic satellite alignment control. Background technique [0002] Mobile communication is a satellite communication antenna servo system with automobiles, ships or aircrafts as the carrier. This system can always align with geosynchronous orbit satellites during the movement of the carrier to ensure continuous and uninterrupted satellite communication links. It is widely used in Emergency communication fields such as public security, fire protection, emergency rescue, and disaster relief. At present, the demand for satellite communication is strong and the development is rapid. Motion-to-communication has extremely broad development prospects in both military and civilian fields. The working process of the mobile communication system is generally as follows: firstly, the vehicle is stationary on a smooth and unobstructed road, and the inerti...
