Abstract

In this paper we investigate GPS signal acquisition and tracking using software GPS receiver. The software GPS receiver consists of a RF front-end, an ADC, and a software GPS program that runs on PC. The RF front-end down-converts the signal from RF to IF, and the ADC samples the IF signal. All the other processing including signal acquisition, tracking, data decoding, and solving position are all implemented in software using signal processing techniques. The local C/A code and carrier replica signals are pre-generated, stored in memory, and used repetitively during signal acquisition and tracking. The concepts of signal processing using software GPS receiver can be applied to the next generation Global Navigation Satellite System and Space Based Augmentation System receivers design.
