DEVICE DETERMINING PARAMETERS OF FLIGHT TO IMPLEMENT AUTOMATIC LANDING OF AIRCRAFT Russian patent published in 2003 - IPC

FIELD: aviation instrumentation. SUBSTANCE: device has radio altimeter, course radio receiver, glide-path receiver, unit establishing landing conditions, receiver of airfield information, receiver of satellite navigation system, unit determining relative coordinates, inertial navigation system, complexing unit, video camera, comparator, computer, radio transmitter, unit calculating direction of lens of video camera and mechanism changing direction of lens of video camera. Coordinates of aircraft relative to runway are found by computer on basis of signal from video camera. Maximum precision is achieved when axis of lens of video camera, axis of runway and vector of flight velocity of aircraft lie in one plane. After it unit establishing landing conditions has capability to execute lading under automatic condition. EFFECT: increased authenticity of determination of parameters of flight and operational reliability. 1 cl, 3 dwg
