The invention relates to a high-precision directional tracking device of a mobile satellite antenna servo system. The high-precision directional tracking device of the mobile satellite antenna servo system is arranged in the mobile satellite antenna servo system and comprises a satellite navigation module, a gyroscope sensor, a magnetic angular transducer and a conditioning circuit module, wherein the satellite navigation module is used for detecting information of the position where the system is located at present, the gyroscope sensor is used for collecting horizontal data, rolling data and pitching data of an antenna, converting the motion data into analog signals and outputting the analog signals to a signal processing circuit, the magnetic angular transducer is used for collecting an analog signal of the elevation angle of the antenna at present, and the conditioning circuit module is used for receiving the analog signals, processing the received analog signals and outputting the processed signals to a microprocessor in the tracking system. The high-precision directional tracking device of the mobile satellite antenna servo system has the advantages that time for finding a satellite is saved greatly and execution efficiency of the system is improved.
Description
technical field [0001] The invention relates to a moving satellite antenna follow-up technology, in particular to a directional tracking device for a high-precision mobile satellite antenna follow-up system. Background technique [0002] With the development of satellite communication technology and automatic control technology, real-time data exchange with satellites in motion will become more and more common, and mobile satellite TV is one of the applications. Nowadays, it is not a problem for people to watch TV at home, but with the improvement of living standards, people urgently need to be able to keep abreast of current affairs news and watch live sports events on mobile carriers such as cars, trains, ships, etc. Mobile satellite TV is convenient can meet such needs. [0003] To realize watching satellite TV on a mobile carrier, the key technology lies in the antenna follower system. The follow-up system enables the satellite antenna to always be aimed at the satelli...
