摘要
将GPS系统用于航天器的导航、定位和授时是目前的趋势。但是星载接收机的高速轨道运动特点有区别于地面用户。通过建立GPS星座与国际空间站的链路进行仿真分析。仿真结果表明GPS星座可以满足空间站的大于4颗卫星的信号可用性需求。
The GPS system for spacecraft navigation,positioning and timing is the current trend,but the orbital motion feature of high-speed satellite receivers is different from that of the ground user.Link established between the GPS constellation and the international space station is simulated and analyzed,and simulation results show that the GPS constellation can meet the requirements of the space station more than four satellite signals available.
