Abstract
During the bidirectional time signal transmission, the position of the motion carrier will
produce a certain displacement relative to the starting position. When the displacement of the motion
carrier has a great influence on the signal transmission time, in order to solve the high-precision time
synchronization problem between the downloading bodies of arbitrary motion trajectories, a geometric
model for the position change of the carrier is constructed. The position coordinates of the sampling
points are obtained by satellite positioning, and the motion trajectory equation of the carrier is
constructed by interpolation estimation. By interpolating the complex motion trajectory of the carrier
and accurately analyzing the velocity vector of the motion carrier according to the trajectory, the clock
difference between the two motion carriers is obtained. Computer simulation results show that for any
motion carrier, the difference of sampling points will cause the time synchronization result to change
within a certain range.
