数字中频GPS信号的MATLAB仿真

aking the closely coupled INS/GPS as the applied target, and according to the analysis for the GPS IF signal and the running conditions on the actual environment and the carrier, the paper gives parameters of the GPS signal delay, Doppler frequency shift, time difference, and combines the signals of many satellites using the analytic expression of the IF signal. Finally, the results in MATLAB show that signals meet the actual conditions based on the simulation calculation for the MATLAB, and proves the correctness of signal through the acquisition, track and arithmetic of the GPS software receiver.
