GPS Receivers are used for both military and civilian applications. This paper presents the GPS Receiver for System on Chip (SoC) application. In this paper the GPS Receiver is been implemented as System on Chip in FPGA board. VHDL modeling for the back end of GPS Receiver is designed. As baseband signal processing is the main aspect in the GPS receiver, it is achieved by this software GPS Receiver. Here the acquisition and tracking of the GPS signals is been designed and the data is recovered. MODEL SIM simulator is used here to validate the VHDL modeling. Hence the software defined GPS Receiver is simulated and implemented in FPGA for navigation purpose along with an analog front end.
