AIRCRAFT LANDING LASER SYSTEM Russian patent published in 2009 - IPC B64F1/18 

FIELD: transport.

SUBSTANCE: proposed system comprises three laser radiators mounted nearby the runway on the side of aircraft landing approach, two of them, glide-path ones, arranged on runway edges and designed to form beams that define glide path, while the third laser radiator is mounted on continuation of the runway axial line and serves to form the beam that defines landing course. Laser radiators represent semiconductor laser radiators that allow varying aforesaid beams in horizontal and vertical planes. Glide path radiators are mounted at a certain distance from runway start. Localiser radiator is mounted to form the beam at preset angle to horizontal plane. Aforesaid distances and angle are determined from relationships including preset tolerable error of aircraft vertical position determination, preset angle of glide path inclination and angle of the beam unobstructed passage above irregularities of terrain.

EFFECT: longer life, minimum power consumption, smaller sizes, higher landing safety.
