FLYING VEHICLES AUTOMATIC LANDING SYSTEM Russian patent published in 1994 - IPC

FIELD: automatics. SUBSTANCE: flying vehicle is drawn into the region of supposed landing at preset height by means of correlation-extremal-navigation system or other navigation means. When preset ranging is achieved, pilot coincides center of raster of videocontrol unit with calculated point of landing by means of manual control unit. In this case optical axes of TV coordinator and laser range finder are guided, and reference image is introduced into memory unit of correlator of TV coordinator. After that chosen area is tracked of underlying surface by means of correlation due to TV coordinator in automatic tracking. Angles of sight are measured, which are used for forming automatic control of flying vehicle. EFFECT: improved precision; improved reliability; improved noise immunity. 2 dwg
