A cost-effective all-weather antenna precise station-keeping tracking implementation method and system

Abstract

The application discloses a high-cost-performance all-weather antenna precise star tracking implementation method and system, and relates to the fields of antenna tracking and satellite application. The method comprises the following steps: obtaining antenna position data, satellite orbit data and bit protection data; calculating the spatial orbit position of a satellite in a future time period, generating antenna guide data after correcting the pointing error of the antenna; publishing the antenna guide data to an antenna control unit; and controlling the antenna to point to the satellite according to the antenna guide data. The antenna guide data is format data of the azimuth angle, the elevation angle and the polarization angle required by the antenna for precise star tracking at any time and any geographical position. The antenna control unit is an execution mechanism for adjusting the azimuth angle and the elevation angle of the antenna. The application simplifies the construction complexity of an antenna tracking system, shortens the construction period, and realizes the function of precise star tracking of the antenna under all-weather conditions at low cost, and is suitable for the automatic tracking of high, medium and low orbit satellites.
