| 摘 要： | 提出了通过建立陆基增强系统来提高双星定位能力的技术方案，对该方案实施的可行性进行了理论分析，给出了陆基导航台和用户接收机的结构原理，分析设计了陆基导航台和双星的时间同步技术方案，对比研究了双星系统与陆基增强／双星系统的定位精度问题，得到了一些有参考价值的结论。增强后的双星系统用户端安装导航处理器，工作方式转为被动无源工作模式。分析表明，对双星系统增强后，提高了导航的可靠性，减小了定位几何系统GDOP，提高了定位精度。

| Abstract: | The feasibility of a scheme to improve the dual satellite positioning precision by building terrestrial radio navigation systems is discussed. The principle of a terrestrial radio navigation station and receiver was presented. The synchronization of terrestrial radio navigation station with the dual satellite was analyzed and designed. The unimproved and the improved dual satellite positioning systems were compared,and it was concluded that the positioning mode of navigation processing unit in the receiver is passive for the improved dual satellite positioning system,and the improved system features higher navigation and positioning reliability, smaller GDOP factor and higher positioning precision. |
