To test the signal synchronization performance for the receiver, an IF GPS signal simulator is built by using FPGA based on IF GPS signal model. GPS signal simulator provides simulation signal source for the design and test of the GPS receiver. This paper presents a digital simulation output of the GPS receiver IF signal, and it has characteristics of low cost, high accuracy and configuration flexibility.
