New correlative algorithm and its fast implementation for the acquisition of Y-code without the use of W-code
GPS military positioning system uses P/Y-code to capture signals and then go through tracking and navigation solution.The feasibility research on the acquisition of Y-code was given without the use of W-code.First the basis of the acquisition method was presented.Then,comparison with the standard co...

| Summary: | GPS military positioning system uses P/Y-code to capture signals and then go through tracking and navigation solution.The feasibility research on the acquisition of Y-code was given without the use of W-code.First the basis of the acquisition method was presented.Then,comparison with the standard correlative algorithm the simulation of the algorithm was given to show the characteristics of the new algorithm.At last a segment FFT-based fast implementation of the algorithm was proposed.The correctness of the fast implementation method was proved and Matlab was used to compare the fast implementation with the basic algorithm to show the high efficiency of the former method. |
