Magnetic Surveys
with UAV


TERREMYS is a UAV geophysical survey company and is characterized by an innovative service for the measurement, processing, and interpretation of magnetic data.

Lightweight UAV Magnetic Surveys

Our L.U.M.S technology allows multi-scale aeromagnetic surveys from 1 to 150 meters using a measuring system weighing less than 500 grams.
This metrological evolution opens new perspectives for geophysical studies applied to the subsoil at depths both shallow and deep while delivering data that meet industry standards and are accurate to the nano-tesla range.

Our innovation
The magnetic compensation of the UAV


Our innovative solution is based on the compensation per figure of merit of the effects of drone magnetization using vector magnetometers. The measurement then becomes possible without a heavy and expensive active compensation system, without having to move or pull the magnetometers, and without having to use gradiometers that are less sensitive to deeper sources.
