Abstract: Aiming at GPS software receiver, this paper proposes an implement algorithm for tracking part including code tracking and carrier tracking. The algorithm is simulated in Matlab based on simulation data and implemented in C based on real data in PC. The C program runs on GT3000A platform which integrates ARCA3 embedded microprocessor. Experiment proves that the algorithm carries out the tracking function of C/A code phase and carrier frequency, and decodes the navigation data.
