The measurement units installed in the aircrafts are connected to each other by local area network (LAN). This makes it easy to install just the right measurement units for each running project. A laptop computer is connected to network and makes monitoring easy. All collected numerical data is seen on display during the flight as well as graphics for magnetics, EM and radiometrics.
Frequencies: 0,9 kHz, 2 kHz, 12 kHz and 25 kHz
AUTOMATIC AEROMAGNETIC DIGITAL COMPENSATOR (AADCII) (Technical details).
