Abstract:

RTK technology is a new measurement techniques commonly used in GPS,it can provide real-time results of three-dimensional positioning of test site in the specified coordinate system.It has advantages of efficient，accurate positioning,lower operation conditions require and easy to operate.RTK technology brings convenient to mapping work,improves the efficiency of the field layout and the accuracy of lofting points and is widely used in the measurement of the mine.But RTK technology also has some shortcomings which mainly caused by the influence of the satellite status,the sky environment and data transmission.Through comparing the review of known piont and the remeasureement and detecting station frequency changes to complete RTK technology.The RTK technology continues to be more mature,it has important significance for mine to speed up the measure progress and reduce labor intensity.

Key words: S86T（GPS）, Mine Surveying, RTK positioning technology, Application
