Simulation and verification of high dynamic IF GPS signal

摘要

Navigation and positioning under high dynamic environments is one of the hottest scientific research fields currently. As the GPS signals under high dynamic environments are difficult to obtain, this paper presents a GPS signal simulation algorithm. Firstly, a mathematical signal model is analyzed. And then the parameters are calculated, and the algorithm for GPS satellite signal simulation is given. The GPS intermediate frequency signal simulator is developed based on the algorithm. Finally, experiments are implemented to verify the reliability and validity of simulated GPS signal.
