Attention:
Operation of the GT-2A requires experienced staff on board the aircraft.
Summary
The mobile gravimeter combines inertial navigation systems (INS), vertical gravity sensors and global positioning systems (GPS) to measure gravity anomalies related to sub-surface geology and structure. It is combined with a JAVAD DeltaQ GPS Receiver.
