Minimizing the Altitude of a Low-Flying Vehicle in the Absence of an Altitude Map

Abstract

The paper proposes a method for minimizing the height of a low-altitude unmanned aerial vehicle in the absence of a terrain elevation map. The essence of the method lies in the desire to approach the minimum gradient of the underlying surface. The track angle of the aircraft, within a certain sector, deviates towards the slant range meter, which gives a larger value. Computer simulation has shown that under certain conditions, using the proposed method, it is possible to sufficiently reduce the height of the unmanned aerial vehicle.
