中南地区地质调查中北斗卫星技术应用研究

主要介绍了基于北斗卫星的野外地质调查系统在丛峦叠障、植被覆盖茂密的中南地区野外地质调查中应用的情况，包括野外作业管理、人员安全保障以及遥感异常查证等。试验结果显示，利用该系统基本可实现野外地质调查人员的实时地理位置显示、历史轨迹回放、态势分析以及路线规划等；试验区内系统的通讯基本通畅，可以实现终端与终端、终端与指挥机之间的双向短报文通讯；利用北斗系统的定位功能，可实时记录异常查证点信息，对室内解译的遥感成果进行及时调整和修改，提高了野外地质调查的工作效率。 

APPLICATION OF BEIDOU SATELLITE TECHNOLOGY IN GEOLOGICAL SURVEY IN SOUTH-CENTRAL CHINA

This paper mainly introduces the application of field geological survey based on the Beidou satellite''s field geological survey system in South-central China area with dense forest cover, including field work management, the personnel security and remote sensing anomaly verification, etc. The test results show that the system can generally realize the field geological investigation for personnel''s real-time geographic position indication, historical track playback, situation analysis and route planning, etc. The Beidou system can communicate effectively in test area, and can realize the two-way short message communication between Beidou terminal and terminal, terminal and Beidou command machine. What''s more, using of Beidou system positioning function can record real time abnormal verification point information, adjust and modify the indoor interpretation of remote sensing results. Thus we can improve the work efficiency of field geological survey.
