UniMaster
UniMaster — multichannel magnetometer and data recorder for geophysical sensors.
In a single 2 kg housing: a quantum magnetometer, a recorder for various geophysical sensors, a GNSS receiver, a magnetic deviation compensator and a front-panel display; an external pilot display connects to the unit.
Instrument configuration

Purpose
Recording of geophysical sensor data
The airborne unit combines a quantum magnetometer, a geophysical sensor recorder, a GNSS receiver and a magnetic deviation compensator.

Magnetic compensation
In-flight magnetic compensation
A three-component fluxgate and adaptive algorithms are used for in-flight magnetic compensation. The graphs show a flight record with roll, pitch and yaw manoeuvres: the magnetic channel before and after compensation, the three fluxgate components and the local component.
