Abstract:

In recent years，with the continuous development of the global positioning system，a new measuring method GPS -RTK technology came into being.GPS-RTK technology using the static measurement mode，mainly use ed for the establishment of a variety of level measurement control network，can be based on the requirements of different levels to provide high precision control measurement results. It is widely used in various industries due to the advantages including nil error accumulation，user-friendliness，high positioning accuracy，high performance in processing data.This article focuses on the application of  GPS-RTK on the controlled measurement in rock gold minefield of Xingfu Village mainly including the establishment of the controlled measurement network in minefield，option of measurement mode，measuring process in field，data process，assessment of accuracy as well as methods of conversion between original coordinate，etc.Out of practice，GPS-RTK technology is used to provide practical solutions for the establishment of control survey network of the gold prospecting area，and to provide accurate and reliable measurement results for geological work，lay the foundation for the further development of geological work in the next mining area.Compared with traditional measuring technique，GPS-RTK has increased efficiency and accuracy，in the meanwhile saved large amount of manpower & material resources and funds，will be vigorously promoted and used in all walks of life，to play an important role in the national economic construction.

Key words: GPS-RTK static measurement, controlled measurement in minefield, control point, accuracy evaluation, data transversion, height fitting
