Action Air Environnement has invented and patented the new TEMas airborne electromagnetic sensor.

TEMas is able to map the subsurface, either for the exploration of natural resources or for dual applications.

TEMas is directly supported by the French State, by a FUI-type consortium with the METIS laboratory (ex Sisyphe UPMC Paris 6) and the BRGM.

It also works in partnership with the Fresnel Institute for the development of hyperspectral techniques.

Action Air Environnement develops tools for underground and out-of-sight exploration for dual applications.


We are equipped with ultra-high sensitivity gradient sensors with potassium vapour optical pumping. Their sensitivity is 0.1 pT.
