Design and Implementation of GPS Signal Processing Platform Based on GP4020

This paper describes the implementation of GPS signal processing platform based on GP4020.The platform uses GP2015 as RF front end of the GPS receiver.GP4020 with ARM7 microprocessor is used to process the GPS signal in baseband.The upper computer displays the processing results.This paper describes the design of the extended circuit to the GP4020, the building of software environment as well as the development of software.The platform can be used to test different GPS algorithms.
