摘要
COMPASS卫星网络采用时分的通信体制,其星间链路的两大功能分别为星间精密测量与星间数据分发及境外卫星控制管理。由于受建站范围的限制,国内的注入站对境外卫星不可见时间长达7小时。为了解决这一问题,文中参考了DT-DVTR路由算法,并针对COMPASS星座构型进行改进,提出了适用于COMPASS卫星网络的路由算法。最后,利用真实卫星抽象的仿真模型对该算法进行了验证,仿真结果表明,该算法满足COMPASS卫星网络的测量与数传需求。
The COMPASS navigation system uses SS/TDMA for its ISL network. Two main functions of the ISL is inter-satellite precision ranging and inter-satellite data distribution. China has limited overseas areas where ground stations may be located. This limits ground station visibility to satellites. To solve this problem,this paper comes up an improved inter-satellite routing algorithm which is based on the DTDVTR routing algorithm for the COMPASS navigation system. Finally,we build a simulation system which is based on the real satellite network. The simulation results show that the algorithm in this paper satisfied the measurement and data transmission requirements.
