Abstract

This paper first gives the theoretical derivation of weak GPS signal acquisition algorithms, then discusses the performance of these algorithms from executive time and detection possibility two parts. The results turn that coherent correlation non-coherent accumulation has the advantage of efficiency in time process, while the bit-edge guess algorithm gains better in detection possibility. As for the coherent correlation with differential accumulation it has larger output SNR (Signal to Noise Ratio) then the coherent correlation with non-coherent accumulation in the same condition. Further work will be done to realize real time acquisition in a software platform receiver based on the useful analysis above.
