Abstract :
The Crosslink Ranging and Inter-satellite communication is the key technology of autonomous navigation for satellite, resulting in a constellation of satellites using a narrow beam antenna, due to the limit of the number of antennas on the satellite that bring a problem how effective allocation of limited antenna to establish inter-satellite links, to achieve inter-satellite ranging and inter-satellite communication. According to the satellite constellation cyclical and finite state, propose a new system which suit inter-satellite ranging and inter-satellite communication and a method which make the smallest satellite position dilution of precision(PDOP) and get the topological structure that have the minimum communication link cost. By means of simulation results show that the single satellite PDOP value is not more than 3, the navigation constellations average PDOP value is 2.2, which meet satellite autonomous orbit determination accuracy requirements, optimize network communication performance, and to reduce the delay of the satellite network communication.
