卫星导航系统是重要的信息空间基础设施,世界上主要的一些拥有航天技术的国家也都十分重视其发展。美国GPS卫星导航系统自开发至今一直是世界导航霸主。我国自主开发研制的全球第三代卫星导航系统即北斗卫星导航系统正处在飞速发展阶段。本文首先将简单介绍北斗导航的工作原理,进而与GPS相关参数和现运行状况形成对比,最终得到与论题相应的观点。
Satellite navigation systems are important information space infrastructures and some of the world’s major aerospace-based countries also place great emphasis on their development. Since the development of the United States GPS satellite navigation system has been the world’s dominant navigation. The third generation satellite navigation system independently developed and developed by our country, namely BeiDou satellite navigation system, is in a stage of rapid development. This article will first briefly introduce the working principle of BeiDou navigation, and then with the GPS-related parameters and the current operating conditions in contrast, and ultimately get the corresponding views of the thesis.
