Study of motion delay correction algorithms in time synchronization

As human exploration and research of science extends from the ground to deep space, for satellites with faster relative motion speeds and time information that is difficult to accurately obtain the time, this paper proposes a POLA motion delay correction algorithm, which only needs the motion speed of one of the two parties of time synchronization and the position information of both parties to correct the motion delay difference, so that the two-way time synchronization accuracy is not affected by the speed accuracy of the poorer party The algorithm only needs the velocity and position information of one of the time synchronization parties to correct the delay difference, so that the two-way time synchronization accuracy is not affected by the velocity error of the party with poor velocity accuracy. The effectiveness of the algorithm is verified through simulation tests.
