Operating and results
Low-altitude aeromagnetic survey using helicopter-type drones is carried out on a scale of 1:2,000 - 1:10,000 with a detailed terrain following in areas of 100-400 km2.
The aircraft-type drone is used to survey more extensive areas on a scale of 1:10,000 or less, when detailed flow around the terrain is not required, which allows flying with general flow at altitudes of 70 m or more from the surface. At the same time, the performance of the aircraft-type drone is up to 1000 km per flight.

At the same time, the performance of the aircraft-type drone is up to 1000 km per flight.
After processing the data obtained by our specialists, maps of the anomalous magnetic field and its transformants are compiled, allowing conclusions to be drawn about the features of the geological structure of the territory.
The standard error of the survey does not exceed 1.5 nT, and the accuracy of the planned and altitude reference after differential processing is of 0.1 to 0.5 m
