Precise UAV-based magnetic survey

It is now possible to get magnetic field data with aerial speed and ground-based precision. We use improved flight control system to perform variable altitude and speed proximity flight. This kind of survey is used in archeology, regional structural geology and man-made structure expliration.

Magnetic field gradient components
Magnetic field gradient components map: a) abs horizontal component b)vertical component

1-2 seconds interval between magnetic field variation measurements.

Field work and data processing according to geological mission.

Flights under FAA regulations.

The survey may be performed at 5 m above plain areas and at 30 m in thick forest conditions.

Proximity flight following the terrain curves.

Up to 200 linear km of precise magnetic survey in 1 day.

Altitude-differencial analysis to create magnetic field anomaly cube.

Magnetic component
a) Magnetic field local component b) regional component (250 m up crosslayers)

Get results:

  • 10 Hz record rate for magnetic field provides 0.8-1 m step on modelled surface.
  • ±2 m average points coordinates error after differential data correction.
  • ±2 nT rms of survey data.
  • at least 5% dedicated for test measurements at different routes.

Geoscan magnitometric complex

Combines UAV flexibility with sensitivity of quantum magnitometer equipped with rubidium sensor. Capable of proximity flight while performing precise aeromagnetic survey.

Provides the ability to inspect volumetric magnetic deviations and vertical component analysis, allowing to use new interpretation methods. This creates next level of precision for geomagnetic models.
