METHOD FOR PRECISION LANDING OF UNMANNED AERIAL VEHICLE

FIELD: physics; control.SUBSTANCE: invention relates to methods of landing unmanned aerial vehicles and can be used when solving tasks for facilitating precision automatic landing of unmanned aerial vehicles on small areas. The method comprises landing an unmanned aerial vehicle in a recovery net, forming a circular approach area, for which an omnidirectional radio-frequency radiation source is placed at a given landing point and a radio direction-finder is mounted on-board the unmanned aerial vehicle, performing autonomous approach of the unmanned aerial vehicle, using standard on-board navigation equipment, receiving signals of the omnidirectional radio-frequency radiation source and performing angular tracking thereof in the horizontal and vertical planes by the on-board radio direction-finder, the data of which are used by an on-board control system to generate a command for self-guidance of the unmanned aerial vehicle towards the radio-frequency radiation source in the horizontal plane. The method comprises simultaneous self-guidance of the unmanned aerial vehicle towards the radio-frequency radiation source in the horizontal plane and flying the unmanned aerial vehicle at a given altitude, upon achieving a given angle of sight of the radio-frequency radiation source in the vertical plane, switching the unmanned aerial vehicle to pitching, from the data of the on-board radio direction-finder using the on-board control system, generating a command for self-guidance of the unmanned aerial vehicle towards the radio-frequency radiation source in the vertical plane, performing self-guidance of the unmanned aerial vehicle towards the radio-frequency radiation source in the vertical and horizontal planes until falling into the recovery net, placed horizontally over the radio-frequency radiation source.EFFECT: improved independence of precision landing of an unmanned aerial vehicle.1 dwg Изобретение относится к области способов посадки беспилотных летательных аппаратов (БЛА) и может быть использовано при решении задачи обеспечения точной автоматической посадки БЛА самолетной конструкции на площадку малых размеров. В способе выполняют посадку БЛА в улавливающую сеть, причем формируют круговую зону захода на посадку, для чего в заданной точке посадки устанавливают ненаправленный источник радиоизлучения, а на борту БЛА устанавливают радиопеленгатор, выполняют автономный ввод БЛА в зону захода на посадку, используя штатное бортовое навигационное оборудование, про
