摘要：

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.
