The Design of GPS Digital IF Signal Simulator

Abstract:

This paper focuses on the study of digital IF signal simulator's Matlab implementation on the basis of GPS system and GPS navigation signal simulator.It includes the simulator's parameter settings (such as the sampling rate,intermediate frequency), then calculates the sampling signal's code phase and carrier phase by determining the signal's propagation delay. In addition,it introduces and simulates the ionospheric model and the tropospheric model,and corrects the sampling signal's code phase and carrier phase.This paper realizes GPS digital IF signal simulator's Matlab simulation,thus it provides the supporting platform for research,development and testing of the GPS receiver's new algorithm
