摘　　要：文章介绍了GPS系统的组成、定位原理、技术特点等;针对传统测量方法效率低下、GPS手持机精度较低难以运用在隐伏矿床的定位预测工作中等特点,探讨了高精度差分GPS在隐伏矿床定位预测中有关矿区大比例尺地形地质图的绘制、物化探网点放样、地质剖面图的绘制、异常检查、工程验证点位确定、标定地质点等方面的应用及注意事项;通过三种方法比较和矿区的找矿实践,认为高精度差分GPS在隐伏矿床定位预测中能发挥很好的效果,值得推广。This article introduces the combination,localization principle and technology characteristic of GPS system.Aiming at characteristics of following two methods,lower working efficiency in the traditional field geological survey and lower precision of hand-holding GPS receiver,application and notice of high accuracy differentiation GPS receiver in protracting of deposit＇s large scale topography and geology map and a typical section plain,disposition of geophysical and geochemistry survey methods,abnormity examination,localization of engineering validate and geology point demarcation etc are also discussed.By comparing with three different methods and analyzing the practice of applications,it is proved that the high accuracy differentiation GPS can got good effects in the localization prediction of concealed deposit and should be extended.
