METHOD OF GUIDING UNMANNED AERIAL VEHICLE Russian patent published in 2014 - IPC F41G7/20 

FIELD: physics, navigation.

SUBSTANCE: invention relates to optoelectronic systems in aircraft instrument-making and can be used in systems for guiding an unmanned aerial vehicle (UAV) to ground targets. The method further involves comparing in the UAV computer, the current estimate of the digital map of the field of the terrain elevation of the region of the target with a map prepared beforehand and inputting into the UAV computer a reference digital map of the field of the terrain elevation of the region of the target on which the position of at least one reference aiming point is given. The value of spatial and angular displacement of the current estimate of the digital map of the field of the terrain elevation relative to the reference digital map of the field of the terrain elevation of the region of the target is then determined, as well as aiming points relative the reference aiming point. Control action is generated to correct the trajectory of the UAV and the position of the aiming point based on information obtained using the optoelectronic system of the UAV.

EFFECT: high accuracy of delivering an UAV to a target.
