摘要
本文对导航卫星的单星定轨进行了初步探讨，针对单星定轨时卫星钟钟差和接收机钟钟差难以处理的特点，提出了定轨的同时解算测站距离偏差和采用平均距离变化率进行定轨两种方案，采用GPS的实测数据试验计算表明，两种计算方案均能初步完成单星定轨任务。
In this paper, the program of single navigation satellite orbit determination is discussed. Two schemes, which can compute the station range bias in orbit determination and use average range rate to calculate orbit, are introduced and applied in the single navigation satellite orbit determination to resolve the problem of the satellite clock and the receiver clock. By the determination of GPS satellite orbit, we find that both schemes can fulfill the work of single navigation satellite orbit determination.
