Abstract

The invention discloses a distributed control system of a mobile satellite communication antenna system. The distributed control system of the mobile satellite communication antenna system comprises a main control subsystem, attitude measuring subsystem and a three-axis subsystem, wherein the main control subsystem calculates mobile communication antenna platform attitude data next time according to intensity data of a satellite beacon signal, mobile communication antenna platform attitude data measured by the attitude measuring subsystem, and data, which are measured by the three-axis subsystem, of different axes of a mobile communication antenna, further calculates angles, which are required to be regulated, of an azimuth axis, a pitch axis and a polarization axis of the antenna, and sends the angles, which are required to be regulated, of the azimuth axis, the pitch axis and the polarization axis of the antenna to the three-axis subsystem; and the three-axis subsystem controls rotation of the antenna in the directions of the azimuth axis, the pitch axis and the polarization axis. After adoption of the distributed control system of the mobile satellite communication antenna system, sensors and a control system are installed nearby, thus solving the problems such as signal attenuation caused by long-distance data transmission of the sensors.

Description
