IMPAC-M – Survey navigation with drape profile option; Data acquisition; support of up to 8 Cs magnetic sensors; Online Magnetic compensation; Real-time coefficient calculation & guidance for the compensation maneuvers is provided by AGIS.
The IMPAC-M can support up to 8 cesium magnetometer sensors. Data sampling rate up to 1200Hz with a high sensitivity & resolution (0.2pT Sensor dependent). Aircraft mounted boom systems have available an optional compensation. The system features a real-time compensation and a recording of compensation data file that can be used for post-mission compensation or re-compensation. The system can also be set with Time Domain EM equipment, synchronizing magnetometer sensor reading with Electromagnetic field pulsation.
