东昆仑地质填图中北斗卫星定位系统应用研究

通过北斗卫星定位系统终端在东昆仑试验区不同海拔高度、天气条件、地貌构造及移动状态下的示范应用,总结归纳了该定位系统在野外地质调查中的应用特点及不足,并对未来北斗卫星定位系统的应用进行了分析。试验应用结果表明,北斗卫星定位系统在提高地质调查效率、保障野外地质调查人员人身安全、野外作业管理以及野外应急服务等方面均可发挥重要作用。系统目前存在的定位精度不尽如人意、定位信号受地貌构造、天气和移动方式影响不甚稳定的现象,是其今后发展中需要重点解决的问题。

APPLICATION OF BEIDOU SATELLITE POSITIONING SYSTEM IN GEOLOGICAL MAPPING IN EAST KUNLUN

According to the application of Beidou Satellite Terminal Positioning System that is tested in different latitudes, weather conditions, tectonic geomorphology and the conditions of moving in East Kunlun Mountain, application characteristics and inadequacy of this system in the field geological investigation are summarized and its development is also stated. The result showed that the satellite terminal positioning system had improved the efficiency, protected geological fieldworkers'' safety, which played an important role in field operations management and emergency services. Currently the positioning accuracy is not just as one wish, for the positioning signal had been affected by tectonic geomorphology, weather and the way fieldworkers moved, and this is the key problems to be solved in the future.
