Precision real-time positioning for fast geophysical prospection

Abstract

In this short report high-precision surveying instruments such as an RTK-GPS and a tracking total station are integrated with a ground-penetrating radar (GPR) system on a motorized sensor platform. This enables real-time navigation and provides accurate three-dimensional coordinates in the national grid system for each geophysical measurement. The correlation between the different data sets is ensured by a unique ID that is attached to each coordinate. As a result of this surveys become much faster and are of higher quality. Experience from a numberof GPR surveys will be described, showing the high positional accuracy that can be obtained. Copyright © 2005 John Wiley & Sons, Ltd.
