| 摘 要： | 全球定位系统(Global Positioning System,GPS)是一种基于卫星的定位系统,向全球范围内的用户全天候提供高精度的导航、定位和授时服务.GPS系统的测距码可以分为粗码(C/A码)和精码(P码),其中C/A码用于民用导航.本文在深入研究C/A码信号生成原理的基础上,利用Matlab对C/A码信号的实现方式进行了仿真实现和分析.仿真结果进一步证实了该方法的正确性和可行性.这对在仿真平台上进一步研究真实环境下的GPS信号,使其能捕获跟踪复杂环境下的卫星信号,改进卫星接收部分的性能有着十分重要的实际意义.

| Abstract: | Global Positioning System (Global Positioning System, GPS)is a satellite-based positioning system, within the scope of global users to provide round-the-clock high-precision navigation, positioning and timing services. Ranging Code GPS system can be divided into rough code (C/A code) and the fine code (P code), C/A code used for civil navigation. Based on in-depth study C/A code signals generated on the basis of principle, the use of Matlab C/A code signals in the form of the realization of Simulation and a... |
