摘　　要：本文阐述了GPS全球定位系统的定位特点、结构性能、观测原理与工作方式．在此基础上分析说明了GPS在地学遥感中的应用价值：（1）野外调查中的定位监测与测量；（2）遥感影象定位校正；（3）GIS地学编码；（4）全球环境信息定位．The GPS is the system for determining the position or receiver by man-made satellite of radio. It is consist of satellites, Contrile on ground and receiver. Many people pay close attention to receivers. The receivers developing is already in third generation. (The volume is little, and the positioning accuraoy is higher).The GPS can be go on point positioning, relative positioning, static positioning and moving positioning. It can be applicated on many territory. On the geo-RS, used to GPS go on positioning and measuring in fieids, go on positioning and calibration to RS image,go on coding to GIS geography information, to provide positioning information for studing of global environment.
