Company History
Geosensors was founded in 1999, specialising in the development of novel airborne and ground-based high-resolution, quantitative sensor technology, and its application to EM soil property measurement and mapping; EM depth sounding and inversion techniques; detection and characterisation of small conductive targets, and electromagnetic sea ice measurement from airborne and surface-based platforms.
Over the last decade, we have intensified our focus on the performance and usability of our hand-held and towed ground conductivity sensors, and have introduced a new R-Series line of cost-effective, all-coplanar geometry sensors to complement the long-standing and very successful Dualem dual-geometry sensor family.
