摘要：

Information sharing and baseline measurement inter-satellites are key technologies for the space based virtual exploring mission of Distributed Spacecraft (DS). The integrated mode of inter-satellite communication and baseline measurement for DS is proposed, the method of precisely ranging and time synchronization by bidirectional Asynchronous transfer frame via inter-satellite direct sequence spread spectrum link are researched, then the iteration algorithm of asynchronous ranging/time synchronization and model error of the algorithm is proposed and analyzed. The experiment results and analysis of experimenting system show that the integrated mode of inter-satellite communication and baseline measurement presented in the paper achieves excellent precision, functions integrated in one device with more effective utilization of radio channel, and provides a advantage design approach for the space mission of DS.
