Mag629/669 Three-Axis Airborne Sensor

Aerospace-qualified three-axis magnetometers | Mag629 and Mag669

These three-axis fluxgate magnetic field sensors are designed to meet the exacting environmental requirements of airborne applications.

  • The Mag629 has a rugged two-part construction, consisting of a sensor head assembly and separate electronics module
  • The Mag669 uses the same sensor head with an unpackaged electronics board that can be integrated into existing systems, to save space and weight

With a full-scale range of ±75μT and very low noise characteristics, the sensors are ideally suited to applications such as vector compensation in airborne magnetometry. The three sensor axes have a concurrent point of intersection, clearly defining the centre of measurement of the magnetic field being examined. The sensing head has an integral cable.

Mag629/Mag669 | Applications
  • Vector magnetometer for Magnetic Anomaly Detection (MAD)
  • Unpackaged sensors for integration in MAD systems onboard unmanned aircraft

Both the Mag629 and Mag669 are used in CAE’s Magnetic Anomaly Detection AIMS (AN/ASQ 508A) and MAD-XR systems respectively. These have been included in a range of platforms including P-3C and P-8I.

The MAD-XR system, including the Mag669, allows for deployment from unmanned platforms or helicopters.

  • Designed to military standards (for vibration, shock and thermal shock) for integration into airborne platforms
  • Low noise (down to < 4pTrms/√Hz at 1Hz) for increased accuracy and noise reduction in the MAD system
  • A low measuring range allows for a higher sensitivity on the analogue output
  • Extended operational temperature range making it suitable for use in a wide range of environments
  • Concurrent sensing axes
  • +28V supply (Mag629) for ease of integration with aircraft power supply
