一种在待测距离未知的情况下求解测控电波时延的方法

Computation of TT＆C Wave Transmission Delay at an Unknown Range

提出了一种在待测距离未知的情况下确定电波在空间单向传播时间的方法。该方法可以迅速地利用前一时刻已经测得的距离和距离变化率，导出下一时刻发送的无线电波到达航天器时其在空间的单向传播时间。利用该时间，可以确定航天器接收到信号时的大概位置。

A method to get the time of one-way radio transmission when the measurement distance is unknown is presented in this paper. This method uses the distance and the variable rate of distance got in advance to calculate the transmission time of the next measurement radio wave. when it gets the radio signal. The time required is got to calculate the next position of the spacecraft
