Attention:
Operation of the GT-2A requires experienced staff on board the aircraft.
Summary
The mobile airborne gravimeter system combines data from a vertical gravity sensor and global positioning systems (GPS) to isolate gravity anomalies related to sub-surface geology and structure. The GPS component is handled by a JAVAD DeltaQ GPS Receiver. Power is supplied via an UPS and the system is operated via 2 touch panel PCs.
