METHOD FOR GRAVIMETRIC SURVEY USING UNMANNED AERIAL VEHICLE Russian patent published in 2019 - IPC G01V7/16 

FIELD: aviation.

SUBSTANCE: invention relates to gravitational measurements by means of moving objects (aircraft) and can be used to perform gravimetric survey required when searching for hydrocarbon deposits under special conditions. Invention is a complex for gravimetric shooting on unmanned aerial vehicles (UAV), consisting of commercially available UAV, capable of flying with external load of more than 8.5 kg and voyage duration of more than 1.5 hours, driven by rotation of six propellers (hexacopter), operating from storage batteries, equipped with three gyroscopes, control unit with triple duplication of all systems; commercially available system of electronic three-axis stabilization of gravimetre (steadicam); commercially available relative gravimeter CG-6 Autograv™, fixed on the stabilization system frame by means of a rubber damper with thickness of 5 mm with a modulus of elasticity of 5–7 MPa; wind screen and stabilization system clamp with gravimeter to drone body.

EFFECT: technical result is creation of complex for gravimetric survey, which enables to measure gravity using the same gravimetric equipment both from air and ground version.
