HSGPS(High Sensitivity GPS)is the hotpot of research in the world,and HSGPS acquisition technique is the most important part.The two acquisition methods are coherent integration and non-coherent integration in common use in HSGPS.In terms of the mathematic expressions and the PDFs(Probability Distribution Function)of the signals in the two methods,the process gains of the methods were present and their changing trends were acquired.And the efforts provided the significant gists for researchers and engineers to analyze signal detection of receivers and to evaluate the working effects of receivers.Finally,the real effects of the two methods were acquired and the theoretic analyses of the two methods were proved in the simulation tests.
