This article has first analyzed the GPS localization navigation principle, in view of its un- voluntary navigation flaw, the analysis has compared the performance of many kinds of assistant navigation system, determined use Dead Reckoning system, composed of electronic compass and milemeter, to complete the auxiliary localization function, when GPS abated. This scheme could get a satisfying short-time precision, and its cost was low.

本文首先分析了GPS定位导航原理，针对其非主动式导航的缺陷，在分析比较了多种辅助导航系统的性能后，采用"电子罗盘+里程计"的DR航迹推算系统来完成GPS失效时的辅助定位，该方案能保证短时精度，且成本低廉。

The left and right sides satisfies China and circumjacent area user to be opposite the demand of satellitic navigation system, have systematic group net and test, expand stage by stage for global satellite navigation system.

在2008年左右满足中国及周边地区用户对卫星导航系统的需求，并进行系统组网和试验，逐步扩展为全球卫星导航系统。

In order to solve the heavy workload and the low efficiency of the train maneuver, one kind of train security alarm system based on GPS and INS technique was presented. The Kalman filter used in the information fusion of GPS and ISN was analyzed, solving the problem of the infinite position error of an INS and the slow modification rate of a GPS. By using the original train database to correct the mileage, the precision of the system was improved.

为了弥补目前火车车辆运行中人工统计调度工作量大、效率低等缺陷，提出了一种基于全球定位系统和惯性导航技术的火车安全告警系统的设计方案；重点讨论了GPS/INS在信息融合时所使用的卡尔曼滤波方法，避免了独立的惯性导航系统无限位置误差和GPS的1 Hz慢速数据修正的问题；利用原有国家铁路网数据库进行数据修正，进一步提高了系统的精度。

Its setup thoroughly solved the problem of domestic applied understructure building for the Beidou satellite locating and navigational system, paving both for the domestic large-scale use and industrialized development.

神州天鸿民用网管系统的建立彻底解决北斗卫星定位导航系统的民用基础建设问题，为北斗卫星定位导航系统的民用大规模应用和产业化发展奠定了坚实的系统基础。
