Universal automatic landing system for remote piloted vehicles

Claim 1

An automatic landing system for landing remotely piloted flying vehicles in a predetermined flight path and at a predetermined point, comprising; (a) an auto pilot carried by said flying vehicle for measuring the parameters of attitude, airspeed, and heading and comparing the same to predetermined parameters for the desired attitude, airspeed and heading, and for adjusting the path of said aircraft whenever deviations from the desired parameters are detected; (b) radar transmitter and receiver means disposed on a stabilized gimbal for measuring the angular deviation from a reference and the actual distance from said vehicle to said radar transmitter and receiver means on a continuous basis; and (c) control means for receiving signals from said radar, transmitter and receiver means indicating the pitch and yaw angle and the range from said radar transmitter and receiver means to the said vehicle, computing both actual and desired altitude and heading angle on a continuous basis and comparing said desired and actual altitudes and heading on a continuous basis from the initiation of landing approach until said vehicle reaches a pre-determined touch-down point, and for transmitting signals indicative of any deviation from said desired parameters to said autopilot for correcting any such deviations from said desired parameters whereby said remotely piloted flying vehicle is landed at a predetermined touchdown point and travels along a predetermined glideslope and heading during landing.
