UTIG aerogeophyscial platform Externally mounted instrumentation includes magnetometer (shown retracted), radar antennas, GPS antennas and sensitive pressure altimeter port. The laser transmits and receives through an access hole in the floor and the gyro-stabilized gravimeter is mounted at the aircraft center of gravity.
