GPS P码直接捕获方法研究

Research on the Method of GPS P Code Direct Acquisition

介绍了GPS P码直接捕获方法的性能,详细论述扩展复制重叠法的原理和性能,从理论上证明扩展复制重叠法是目前技术条件下行之有效的GPS P码直接捕获方法,通过实例验证了理论的正确性.

In this paper, the performance of GPS P code direct acquisition method is introduced, and the principle and the performance of the expansion, duplication and overlapping method are discussed in detail. The expansion, duplication and overlapping method is theoretically proved to be the available GPS P code direct acquisition method in the current technology status. The correctness of the theory is demonstrated by the examples.
