Groundradar has been working with RioTinto to develop a custom radar system for use at their Weipa bauxite operations in Australia. The ultimate system will be a real-time sampling, multi-frequency, completely wireless and waterproof radar which is designed to map both the depth of bauxite as well as the fine detail of overburden thickness and lithological variations within the bauxite. Positioning will be accomplished through the use of a RTK GPS at 20 Hz.
