The design of GPS IF signal software simulator

Abstract

This article designed a GPS IF signal simulator 1which is based on the software; it can simulate the GPS IF signal after the user assigned the moving condition of its carrier. It is very facility for the GPS software receiver to research or validate its arithmetic. The papers start with GPS IF signal architecture; illustrate the theory and arithmetic of simulator, then give the detail flow chart for generating the signal. At last use the software receiver to acquire and track the signal generated by the simulator and confirms it.
