Autonomous positioning of an unmanned aerial vehicle (UAV) with limited weight and size parameters in space requires correction of the strapdown inertial navigation system (SINS). Corrective corrections are determined by the method of visual navigation on special points of the underlying surface. For effective application of the method of visual navigation, it is necessary for the UAV to fly at a sufficient height to identify the required number of special points.

Determination of sufficient altitude of the aircraft to correct strapdown inertial navigation system in the absence of satellite signals using intelligent geospatial information system (ISGI).

The article presents a technique that allows to calculate a sufficient height of the UAV flight over the correction area by applying algorithms: formation of correction areas by an intelligent geospatial information system, calculation of the UAV trajectory to the start point, calculation of the UAV flight altitude, correction of sins. The significance of the research is due to the formation of coefficients characterizing the sparsity of the underlying surface descriptors and the share of the reference image in the current one, which allow determining the correction corrections of the UAV navigation system.

The application of the methodology for determining a sufficient altitude, it allows Autonomous position of the UAV in space preserving acceptable accuracy of determining location coordinates, to reduce resource-intensive computations on continuous monitoring of the underlying surface and identify specific points to take into account the instrumental errors, the sins and characteristics of optoelectronic systems.
