摘　　要：针对航标、航道地形、碍航物等典型航道要素的高精度定位应用技术,并结合北斗地基增强系统推广应用,综合SPP、RTK、DGNSS、PPP等高精度定位技术手段,首次系统研究了长江航道典型航道要素的定位精度指标以及适用于长江航道的导航定位集成技术方案,并兼顾相关定位技术手段的先进性、可操作性、适应性等在长江航道开展试验研究,制定应用方案,解决助航设施、移动信息采集设施、船舶等定位应用技术问题,提高航道要素信息感知的可靠性,避免定位精度不够导致的决策失误或不满足应用需求的情况发生,全面提升航道维护管理和综合服务水平。In view of the high-precision positioning technology for the navigation mark, channel topography, obstruction and other typical elements of the channel, and combining with popularization and application of Beidou foundation enhancement system, we integrate SPP, RTK, DGNSS, PPP and other high-precision positioning technology to study the positioning accuracy of typical channel elements in the Yangtze River channel and put forward integrated technical scheme for navigation and positioning of the Yangtze River for the first time. Taking the advanced nature, operability, adaptability of related positioning techniques into account, we carry out the experimental research in the Yangtze River channel and develop the application program to solve problems of positioning technology of navigational aids, mobile information collection facilities, ships, etc., to improve the reliability of information perception channel elements, and avoid mistakes or occurrence of not meeting the application requirements due to insufficient positioning accuracy, so to enhance the channel maintenance management and integrated services comprehensively.
