| Abstract: | A GPS IF signal computer simulation method is proposed in this article. The carrier Doppler frequency and the total propagation
and delay time can be modeled or calculated with the input GPS satellite ephemeris file. The simulated GPS IF signal outputs
to a text file for post-processing and analysis. The simulation signal spectrum is compared with the received real GPS IF
signal spectrum, and the correctness of the simulation result is verified.
