Real Time Kinematic GPS in Open Pit Survey – A Case study at Goldfields Ghana Limited, Tarkwa, Ghana

Abstract

Existing control networks in most mining companies were established using traditional methods of survey such as precise traversing and triangulation, making survey operations time consuming and laborious. Global Positioning Systems (GPS)
technology has revolutionalised the geomatics industry and its applications are becoming widespread in Ghana. Planimetric control positioning and detail pick-ups using the Real Time Kinematics Global Positioning System (RTK GPS) is emerging as one of the fastest, reliable and more accurate methods of surveying in surface mining. This paper seeks to highlight
how the RTK GPS from Trimble is being employed at Goldfields Ghana Limited (GGL). The usage, accuracy, advantages and disadvantages of this system in a mining environment are explored.
