ABSTRACT:
A system is provided for remote determination of the attitude of a moving hicle. The system utilizes two remotely located transmitting-receiving stations and two retroreflecting single plane roof prisms mounted on the vehicle which may exhibit high angular rates about a roll axis. The two remotely located transmitter-receiver stations provide laser tracking of the vehicle, continuously illuminating the vehicle with a laser beam located at each station so that the position of the vehicle relative to the remote stations is obtained. During tracking, the roof prisms located symmetrically on the vehicle provide both a return signal to the laser station regardless of the aspect angle of the vehicle and a doppler signal indicative of the vehicle aspect angle, from which the vehicle attitude is determined.
