A Parallel Method in Matrix Form for GPS P Code Direct-acquisition

Under the weak signal environment,GPS P-code is of high level of anti-deception and anti-spoofing.To deal with the features of long code and aperiodicity,we present a direct acquisition with matrix method in this paper.Based on the analysis of direct average method theoretically,a direct acquisition method with matrix is designed which is used to acquire the P-code fast.Therefore,on the basis of researching the relevant theory,a hardware system for verification based on the matrix direct acquisition method is achieved.After the test of the designed acquisition system in weak signal environment,the result shows the method we designed can improve the hardware efficiency by reducing the acquisition time and improve the efficiency of data processing.
