N2 - With the development of the BEIDOU satellite navigation system, its receiver sensitivity requirements continue to rise. Compared with tracking, it is difficult to improve the sensitivity for the reason that acquisition needs a larger amount of calculation and faces a high real-time requirement. As a result, acquisition is the key factors limiting the sensitivity. In this paper, in order to improve the Compass B1-frequency signal acquisition sensitivity, it designs a standard called the mean detection probability based on the analysis of the pseudo-code mismatch, Doppler mismatch, coherent integration, non-coherent accumulation, detection probability and false alarm probability. According to the standard, it achieves a high sensitivity of -147 dBm Compass B1 signal acquisition method and it is verified by simulation.
