Data Acquisition with Magnetics (IMPAC-M)

IMPAC-M is a real-time data acquisition and navigation system designed for airborne (fixed wing and helicopter) geophysical exploration, environmental science, and monitoring applications. Housed in a  single rack-mountable enclosure that meets aviation requirements, the IMPAC-M follows NUVIA Dynamic’s modular design structure producing highly flexible and easily reconfigurable instrument for Airborne surveys.

The system provides survey navigation with a drape profile option;  data acquisition;  support of up to 8 Cesium magnetic sensors; online magnetic compensation; real-time coefficient calculation and guidance for the compensation maneuver.

As a data acquisition platform, it supports a wide variety of proprietary “intelligent” instruments and third party sensors and instruments (E.g. magnetometer sensors, radiation detectors, airborne gravity-meter) can be quickly and easily interfaced.

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.
