| 摘 要： | 编队飞行卫星间的距离和时间差测量是实现分布式航天器完成特定任务的重要基础。文章分析了采用双向法实现星间距离和时间差测量处理时,卫星运动对星间双向比对测量的影响,推导出在考虑卫星运动情况下,星间双向比对测量数据的处理算法,给出了忽略卫星运行参数情况下,对距离和时间差计算结果的影响情况对比。

| Abstract: | The satellite-to-satellite range and time difference measurement were necessary to distributed spacecraft and formation flying systems.The method of inter-satellite two-way time transfer (TWTT) is presented.The measurement data process algorithm for TWTT is deduced and the movement influence on TWTT is analyzed in detail.And then the range and time difference errors are given when satellite movement is ignored. |
