Abstract
Combined with the development background of “The Belt and Road Initiative”, the constellation configuration model of the BeiDou-2 is simulated in this paper. Without increasing the number of satellite, the track of subsatellite point is shifted through changing the orbit parameters to expand the system coverage area. The STK and MATLAB are interlinked, and the orbit parameters are optimized by MATLAB with powerful programming and calculation function. The optimization result shows that service ability in extended area can be realized meanwhile high accuracy positioning in key area to some extent can be improved. The system will offer service at the lowest cost and the shortest time to achieve the greatest benefits. In addition, it also provides reference for future location of satellite drift to enhance effectively local combat security system.
