GT-2A Airborne Gravimeter
The GT-2A is based on 7 years of operational experience with the GT-1A
which brings proven design and fully automatic operation
to mobile scalar gravity measurement.
GT-2M Marine Gravimeter
The GT-2M marine gravimeter is a world-leader in its class.
For accuracy, resolution and dynamic range it is
superior technology to traditional zero-length spring devices.
GT-1A Airborne Gravimeter
The GT-1A airborne gravimeter is a world-leader in its class.
For accuracy, resolution, productivity and dynamic range,
its technology is superior to traditional zero-length spring devices.


When CMG was incorporated in 2002, more than six years of research had been completed by CMG founders and their Russian partners on a state-of-the-art mobile gravimeter. By the end of 2002 CMG was finalising validation of the technology and had carried out extensive and successful airborne and ground tests of the GT-1A gravimeter in Australia. In February 2003 CMG signed a long term exclusive distribution and commercialization agreement with Gravimetric Technology in Russia, manufacturers of the gravimeter. The agreement permits CMG to sell or lease GT gravimeters to the geophysical exploration sector worldwide and also to exclusively carry out further research and development together.
