high dynamic GPS signal simulator can precisely generate GPS signal that the receiver get.After a thorough analysis of the signal received by the GPS receiver
it is found that in the GPS signal simulator the frequency of the code and carrier and the time delay of the signal spreding are computed at a certain interval according to the receiver time.Since there is a acceleration between the receiver and GPS satellites
the interval of the signal transmit time is not equal to the interval of the signal sampled time.The computation method for the GPS signal in the high dynamic condition is presented.Based on the error analyse of the model
the method with the increasing the sampling rate for minimizing the errors caused by the simulation of the high acceleration signal is proposed.
