The advanced Multicopter Aeromagnetic Survey System utilizes Atomic Rubidium Magnetometer/Vector Fluxgate Magnetometer/Aeromagnetic compensation technology, providing high-resolution and high-sensitivity magnetic data acquisition basing on drones platform. Common Applications for Aeromagnetic Survey system •Mining exploration(iron, gold, copper, tin, diamonds (kimberlites) Marine geophysical exploration •Unexploded ordnance (UXO) detection •Utility location •Archaeology •Regional geology The vertical takeoff and land(VTOL) fixed-wing UAV has the advantages of high efficiency, low cost, and is suitable for large area, smooth terrain or marine mobile platform operation. The VTOL fixed-wing UAV optical pump and fluxgate aeromagnetic system(GTK-R15M) were selected as the top ten scientific and technological progress in China in 2019. The project was finished in the sea area of Pearl River Estuary in the north of the South China Sea. Highlights test: 1) A major breakthrough in the technology of "air-sea geomagnetic field joint survey" has been made . 2) The technical method of accurate take-off and landing of UAV on mobile platform and synchronous operation with marine magnetic survey has been realized.
