| Nowadays, satellite communication of mobile carriers is being paid attention to by people day by day . In military affairs, with the development of weapon equipment of our troops, there are more requests to fast reaction and flexible ability of the equipment and the ability of teady aim , track and attack. Civilly, with the development of civil system such as satellite TV, satellite network and video telephone etc., the demand for mobile communication of the carrier is more and more urgent. The key equipment of mobile carrier satellite communication system is the automatic tracking system of satellite antenna. Satellite antenna automatic tracking system is used mainly for track and orient of mobile carrier satellite communication so as to ensure that the aerial can aim at the synchronous satellite appointed automatically and aim at the satellite incessantly with high precision under the condition that the vehicle moving (various speed;urgent startup; stop and swerve and so on ) and under various kinds of meteorological phenomena, so that realizing the sending and receives of the satellite information incessantly. Developed country have correlative products appeared already , but costly at present. There is no applied antenna auto-tracing system used in mobile satellite communication in our country now. So, it' s very significant to develop satellite antenna auto-tracing system with rational capability and price ratio and fill up the domestic blankness. This paper took the auto-tracing system development of ship antenna as the background, studied the pose measure and control technique based on digital compass and GPS combined sensor. The main contents of the task research include: the integer framework and track scheme design of antenna auto-tracing system, the principium and capability analyze of the combined pose sensor, hardware model choice, and giving one king of system settle scheme based on LabWindows/CVI and Visual C++ amalgamation technic. |
