Airborne gravity surveys are an effective exploration tool that provides reliable signal, allows for more coverage in a shorter amount of time.
EDCON-PRJ conducted their first airborne gravity test using the DGS with inertial guidance in a small aircraft. The goal was to compare the gravity data acquired in the Cessna 180 with 82 public domain stations and 1,385 Getech land gravity data present throughout northern Colorado.
The AT1M Gravity Meter, which was installed in the rear cabin of the aircraft, incorporates an advanced GPS-guided platform control system and inertial navigation corrections that allow for the acquisition of high-resolution data using light aircraft following a pre-planned drape surface.
Results show that the data acquired correlate well with the land gravity data. This aircraft permits for small drape guidance and because of the size and cost of operation, it offers airborne gravity services at a lower price point than larger, conventional airborne gravity aircrafts.
