Research on Fast Acquisition of GPS Signal
Wei Li · Avionics Technology · 2006
One of the difficulties of designing GPS receiver working under high dynamic circumstance is to fast acquire the satellite PN code. In this paper, the method of Sliding Window Correlation is analyzed. In order to shorten the PN code acquitting time, the scheme based on FFT is also provided. The method provided is efficiently used in the emulator system with matlab. The emulation results show the capturing speed can be significantly improved.
