The mobile airborne 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. Power is supplied via an USV and the system is operated via 2 touch panel PCs. Sensor-Info: aircraft:bt-67:gt2a_sn028, 6810 |
