Abstract

The invention discloses an automatic compensation system and a compensation method of gesture of a portable satellite antenna. The system comprises an antenna controller used for calculating theoretical azimuth angle, pitch angle and polarizing angle of the antenna and controlling other devices to work, a polarization transmission device used for driving the antenna to rotate in polarization mode, a polarization potentiometer used for feeding back polarization sampling, an azimuth transmission device used for driving the antenna to rotate in azimuth mode, a pitch transmission device used for driving antenna to rotate in pitching mode, a tilt angle sensor used for measuring tilt angle parameter of the antenna in real time and feeding the parameter back to the antenna controller and a global position system (GPS) used for providing satellite tracking parameter. By means of the system and the method, the pitching angle of the antenna keeps actual working direction all the time in the star finding process, polarization errors caused by terrain shapes are compensated in real time, antenna star finding speed and polarization adjustment accuracy are greatly improved, and interference to satellite communication caused by polarization errors is reduced.

Description

technical field [0001] The invention relates to the technical field of portable satellite antenna control, in particular to an automatic attitude compensation system and compensation method for a portable satellite antenna. Background technique [0002] The attitude adjustment of the traditional automatic control portable satellite antenna generally calculates the azimuth, elevation and polarization angle parameters when the antenna is working against the satellite according to the longitude and latitude of the antenna working point, the ground tilt situation, and the working satellite parameters, and then controls the antenna according to the set of parameters Go to the working position for star hunting. This method only considers the vertical tilt angle in the front-back direction of the antenna, and does not consider the lateral tilt angle in the left-right direction of the antenna. In the actual use of portable antennas, the ground at the working point not only has a lo...
