High Resolution Airborne Geophysics

Gravity

Using our GT-1A gravimeter along with our geophysical surveying aircraft allows us to gather data of unparalleled quality. The dual dynamic range and virtually no cross coupling allow quality data to be gathered even in periods of turbulence. The unique GSE suspension design ensures undesirable horizontal accelerations due to aircraft motion are minimized and therefore data can be gathered during aircraft turns or flight direction changes, enhancing survey efficiency. The fact that both our gravimeter's and aircraft are UTS Geophysics owned and operated means we can offer our clients the best value for money service.
Typical applications include the mapping of sedimentary basins for oil and gas exploration and collection of data complementary to magnetic and seismic data sets, both onshore and offshore.
