Ground station antenna tracking method for SIGSO (slightly inclined geosynchronous orbit) communication satellite

The invention provides a ground station antenna tracking method for an SIGSO (slightly inclined geosynchronous orbit) communication satellite. The method includes: selecting the SIGSO communication satellite planning to carry out communication application, and downloading the two-line orbital element (TLE) of the SIGSO communication satellite from the internet; calculating subpoint coordinates of the SIGSO communication satellite in an operating period; calculating an azimuth angle and a pitch angle between a satellite communication ground station and the SIGSO communication satellite according to coordinates of the satellite communication ground station and the subpoint coordinates of the SIGSO communication satellite; debugging azimuth angles and pitch angles of antennas at the satellite communication ground station to realize tracking of the SIGSO communication satellite in the operating period by the antennas at the satellite communication ground station.
