Abstract :
This paper describes a new software method called "averaging correlation" to do block level GPS C/A code acquisition and tracking in frequency domain with smaller FFT blocks. The method retains the signal to noise ratio observed in more expensive correlators. Frequency domain software processing will become more feasible and popular if this method is implemented in civil GPS receivers
