摘要
导航电文设计的优劣直接影响卫星导航定位的可靠性,该文以GPS和Galileo导航系统的导航电文设计为例,汇总了GPS和Galileo系统导航电文设计的最新成果,比较分析GPS传统的导航电文格式NAV和新的民用导航电文格式CNAV以及Galileo系统的导航电文,并对导航电文数据结构、编排方式、差错控制以及播发方式等方面的性能进行评估,进行导航电文的优化设计,以期为我国北斗导航系统的电文设计提供借鉴。
The design of satellite navigation message directly affect the reliability of satellite navigation and positioning, this paper mainly based on GPS and Galileo message design and summarizes the latest results of GPS and Galileo message design, through the analysis and comparison of traditional GPS navigation message NAV,new navigation message CNAV and Galileo navigation message,then the performance of the navigation message is evaluated in some aspects such as message data structure, error encoding performance and broadcast mode.etc. Finally, this paper studies the optimal design of the navigation message in the hope of providing references and recommendations for the COMPASS navigation system message design.
