METHOD OF GUIDING AIRCRAFT TO GROUND FACILITIES Russian patent published in 2014 - IPC F41G7/22 

FIELD: physics, navigation.

SUBSTANCE: disclosed is a method of guiding aircraft to ground facilities. In the method, guidance to ground facilities is controlled simultaneously in an inclined plane whose position is determined by the flight path direction of the aircraft, and in a vertical plane, based on a condition for providing and stabilising the required resolution of radar images of ground facilities, using a proportional navigation technique with offset of the line of sight rate of the ground facility in both aircraft control planes. Offset values are generated such that the direction of the velocity vector of the aircraft in the vertical plane at moment in time matches the direction towards the point of intersection of the perpendicular to the projection of the line of sight of the ground facility on the horizontal plane, which coincides with the ground surface, passing through the ground facility and belonging to said horizontal plane, with the vertical plane in which the velocity vector of the aircraft is located.

EFFECT: high accuracy of guiding aircraft to ground facilities.
