Novel Method for Non-GNSS Hovering Control of Unmanned Aerial Vehicles

Today, there are many practical tasks that require hovering near a selected point for long periods of time in windy conditions. Most of the existing solutions in this area are based on the use of satellite navigation or similar systems designed to determine the absolute spatial position of the aircraft relative to the ground. This paper proposes a novel method for hovering implementation based on distance measurement to a target point using a minimal set of sensors.The paper investigates the influence of controller parameters on the flight trajectory and proposes a method for control system tuning. Finally, the promising application areas for the proposed methods are analyzed: radio retransmission, swarm control, emergency return-to-home and autonomous soaring.
