【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。本文在深入研究GPS信号捕获原理的基础上,利用Matlab对GPS信号的捕获过程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、改进卫星接收部分的性能有着十分重要的实际意义。更多还原

【Abstract】 The global positioning system(Global Positioning System,GPS)is one kind based on the satellite positioning system,all- weather provides the high accuracy to global scale’s in user the guidance,the localization and the time service.This article in the dee Presearch GPS signal capture principle’s foundation,carried on the simulation using Matlab to the GPS signal’s capture process to re- alize and to analyze.The simulation result further confirmed this method’s accuracy and the feasibility,this to further studies under the true environment in the simulation platform the GPS signal,the improvement satellite receiving unit performance has the very vi- tal practical significance.更多还原
