摘要
中国区域定位系统(Chinese Area Positioning System,CAPS)拟采用比地球静止轨道(Geostationary Earth Orbit,GEO)高150 km至300 km的倾斜高圆轨道(inclined Highly Circular Orbit,iHCO)通信卫星组建全球导航通信星座。基于全球范围内的卫星测控网分布情况,分析了测控站对倾斜高圆轨道卫星的可见性,提出测控站布局的优化方案,并研究了站星链路的方位角、俯仰角和距离特性。
The inclined Highly Circular Orbit (iHCO) communication satellites, which are on orbits 150-300kin above the Geostationary Earth Orbit (GEO), can be used to build global navigation and communication constellation of Chinese Area Positioning System (CAPS). Based on the development of the world telemetry, tracking, and command (TF & C ) network, this paper analyzes the visibility of iHCO satellites, puts forward the optimization layout of TT & C network, and explores the azimuth, elevation and distance (AER) characteristics of the satellite-ground links.
