Measuring with the Global Positioning System (GPS)
Data aquisition via GPS and DGPS
GPS makes it possible to determine the location of any point on the planet. Due to its ability to pinpoint locations within centimetres, this system is particularly suitable for producing topographical surveys of areas with suspected explosive ordnance. Röhll uses the Global Positioning System (GPS) to obtain data to measure areas being surveyed. Any obstructions found are recorded in the digital maps.
GPS is also used in combination with Differential Global Positioning System (DGPS) mapping for computer-aided sounding. In this case, real-time coordinates are allocated to the relevant anomalies via a module box to make them much easier to find after the analysis.
