The Study On Satellite Communication In Motion Basing On Panel Antenna

With the evolution of satellite communication techniques, satellite communication in motion has already been a good instrument in mobile communication, more and more military and civil devices fitted satellite communication antenna, achieveing remote and uninterrupted communication with earth surface . Especially in modern war, terminal of satellite communication was pressed for possessing fine flexibility.The study on satellite communication in motion bases on panel antenna in this paper. First ,basic concepts ,long term potential, comparison of scheme,difficulty and key questions in studying on satellite communication in motion was elaborated. A satellite communication in motion system basing on panel antenna is particularized and subsystems is listed . Aiming at the key question of direction and track of satellite communication in motion a correcting error compensation process basing on vector is presentated, in order to account for quantization error of digital phase shifter, and then the digital phase shifter can feed back phase in regular pattern to achieve the goal of stability direction. It has been stated that this method can let antennat to achieve upper pointing accuracy.The key study of satellite communication in motion includes the following aspects: step length selection , algorithm of step tracking, switch each balanced state. Besides hardware system, software designs have been done in each kind of working state,and it has been applicated in project design.
