Abstract

Abstract: Simulation and optimization for antenna coverage characteristics of inclined GEO satellite with multi-beam antenna were presented from the view of satellite orbit, antenna and pointing. Firstly, the problems of inclined orbit, sub-beam installation, inclined orbit control and beam dynamic pointing were analyzed and formulated for dynamic coverage calculation. Secondly, the evaluation indexes of antenna coverage were constructed and optimization model was built for antenna coverage. Finally, the simulation results show that the uncover problems can be solved and the coverage characteristics can be improved by optimizing the antenna pointing.

Key words: Inclined orbit, Attitude bias control, Multi-beam antenna, Coverage optimization, Modeling, Simulation, Geo-synchronous orbit satellite
