摘要
首先,分析了移动闭塞系统及其定位导航技术的研究现状,建立了基于网络实时动态测量(RTK)技术的GPS/INS/MM的定位导航组合方案;然后,提出了用伪距差分计算用户站概略位置和用载波相位差分计算整周模糊度单差值的快速差分算法,并讨论了有助于列车导航和控制的列车信息移动管理和基于GPRS的数据通信等;最后,对网络RTK快速差分算法进行了仿真分析,其结果验证了该算法对实现列车实时精确定位导航的可行性.
After analyzing the status quo of moving automatic block system and its positioning and navigation technology, this paper constructs the integrated GPS / INS / MM positioning and navigation scheme based on network real time kinematic （RTK）, and presents the fast double-differential algorithm in which the pseudo-range differential algorithm is used to calculate the approximate position of user station and the single-difference of the integer ambiguity is given by the carrier phase differential algorithm. Then, the moving management of train information and the data communication based on general packet radio service （GPRS） are discussed for train navigation and control. The preliminary simulation for the fast differential algorithm based on network RTK proves its feasibility to the precise train positioning and navigation in real time.
