SUBSTANCE: invention relates to the field of aviation, in particular, to designs of unmanned tethered aviation complexes for differentiated application of fertilizers and agrochemicals in the system of precision farming. Unmanned tethered aviation system comprises a helicopter-type drone (UAV) (1), a fertilizer and agrochemical application module (2), external suspension system (3) of module (2), mobile ground station (4) for supply of fuel, electric power, data transmission, supply of working fluids on board of UAV (1), multifunctional harness (5). External suspension system is equipped with lifting-lowering unit (16) with drums (22–25) with independent electric drives for winding-winding slings (17-20) and multifunctional cable (21). Module (2) is made in the form of a rhombus with rod (28) with sprayers (29). Bar length makes at least one drone rotor diameter. One of the end elements of the bar with sprayers can be lowered or raised through an angle of not less than 45°.
EFFECT: increased efficiency and quality of processing agricultural fields, plantations, vineyards, regardless of the terrain.
