针对我国自主研发"北斗二代"导航系统建立全球范围的地面监控站面临着巨大难题的现状,本文提出一种仅在国内建立地面监控站以实现对导航进行实时监控、定位、授时等功能的设计方案。对照美国GPS的地面部分功能,从测定导航的空间坐标、钟差估计、导航电文的注入和大气数据采集四个方面分析了该设计方案的可行性,初步得到该方案具有成本低,满足精度要求,实时性较强的特点。 更多还原

【Abstract】 For the great difficulty of Chinese independent R&D compass Satellite Navigation System in the establishment of worldwide ground monitoring stations,in this paper,a kind of ground monitoring stations designs that only establish in the country have been proposed,which could achieve real-time monitoring satellites,positioning,timing and other functions.To contrast the functions of U.S.GPS system ground monitoring stations,the feasibility was analyzed form measuring the coordinates of the satel... 更多还原
