基于北斗导航系统的地月空间超大时延星间链路测量方法
By adjusting the launch time and code phase of the Earth-Moon spacecraft, a new TOA prediction algorithm was designed, which solved the problem that the BeiDou inter-satellite link could not measure the ultra-large time delay between the Earth-Moon spacecraft and the satellite, and realized effective ranging of the Earth-Moon inter-satellite link.

Abstract
本发明公开了一种基于北斗导航系统的地月空间超大时延星间链路测量方法，地月飞行器计算发送时刻相对于北斗卫星的时隙脉冲超前调整量，调整发射码相位后在设定的发射时隙发射信号；北斗导航卫星基于北斗卫星接收TOA预报算法预测信号的到达时刻复现码相位，接收信号并计算单向测距值；北斗导航卫星发射信号，地月飞行器基于地月飞行器接收TOA预报算法预测信号的到达时刻，复现码相位并计算单向测距值；根据北斗导航卫星、地月飞行器分别计算得到的单向测距值，计算得到星间链路的距离。本发明在现有的北斗星间测距体制制约下实现北斗卫星和地月飞行器的双向比对测量。
