Promising direction of airborne geophysical implementation of UAVs is in the field of mineral exploration. Traditionally, airborne geophysical studies in this field are based on manned, using AN- 26, AN- 3 and Mi-8 helicopters for which exist series different combinations of aeromagnetic prospecting, gamma-ray serveying and aeroelectric prospecting methods.
Obvious advantages of airborne geophysical studies are their high efficiency (up to 200 linear kilometers per hour) and the regularity at hardly- and inaccessible areas. Disadvantages are: high cost of works (up to 15000 RUR/km), unprofitability and practical impossibility for smaller (less than 100 km2) and remote sites, lack or even absence of airport infrastructures, a large amount of security requirements for manned flights. Application of UAV will solve these problems by transferring work on organizing the flights directly to the site of geological exploration, making airborne geophysical studies for any profitable areas of research and exploration available to small businesses.
As a first priority of geophysical mineral exploration technology, integrated with UAVs, it is advisable to use aerial magnetic survey - the method of measuring magnetic field of the Earth and identification of natural and man-made origin of generating anomalies objects. With increasing the payload capacity is planned to develop electromagnetic prospecting UAV's based technology.
Such hardware-software complex will allow essentially cut the costs of airborne geophysical surveying, as well as, in some cases, replace the terrestrial low productive magnetic prospecting. As the final product is scheduled to present to the market aerogeophysical complexes based on UAV for aerial geophysical surveying.
