This paper uses Simulink module to generate equivalent GPS IF signal instead of real signal,adding messages of real pseudo range and rate for simulate receiver’s time difference and bias.All baseband signal processing procedures are carefully investigated,the performance of FLL are discussed in details.An optimized method is chosen into the model.An absolute receiver is completed by least squares method.Simulation results show the availability and reliability of the software receiver and a whole receiver system can be finished by software simulation.
