Map subtle changes in geology and lithology
Map thin gravels, clay layers or discrete targets
Map to greater than 250m (far greater than fixed wing time domain electromagnetics “FTEM”)
Extreme early time gates, especially with system response to map top few metres in high resolution
The use of SkyTEM airborne TDEM to provide solutions for geotechnical engineering problems is an evolutionary application of our technology stemming from the low noise, high-bandwidth data we gather. This allows for extremely near surface mappin in detail couple with obtaining information at depth to build comprehensive integrated models of the sub-surface structure, groundwater and geology.
The SkyTEM method delivers accurate, high resolution, precisely positioned measurements giving scientists and engineers a better understanding of geology, hydrology, and natural and manmade hazards. SkyTEM projects include pre-construction engineering for pipelines, tunnels, harbours, mine site infrastructure, slope stability studies, overburden thickness determination, identification of fractures and faults and location of aggregate deposits and water resources.

SkyTEM is of high value to engineers as it provides a multi-sensor platform that collects various types of data concurrently, including:
The SkyTEM system was purpose built for near surface applications and in the early days that related mainly to groundwater however the systems unique capabilities of operating with dual moments provides ultra high resolution near surface providing excellent data for many geotechnical programs.
As the only system capable of operating in dual transmitter modes SkyTEM delivers accurate near surface data together with data specifically configured to resolve the small differences in conductivity while maintaining a moderate depth of penetration to image underlying structure and geology, giving a complete picture. The system discriminates between weak geological contrasts giving a more complete and accurate interpretation of geology while increasing confidence in modeling deeper geological structure.
