DISPOSITIVO DI TELEMETRIA OTTICO-ELETTRONICA A BASE VARIABILE

Optic-electronic telemetry device suitable for determining, on the basis of informations of angular measurements supplied by two independently mobile and mutually cooperating units (SI, S2), of reception in predetermined bands of frequency, the spatial position of a third unit (B), of transmission in the same frequency bands, relative to the same known references in space and time, characterized in that each of said two independent units (SI, S2) is provided with first means for aiming and keeping aimed on said third unit (B), in that said two units are connected by means of second means of information exchange in real time and in that said device comprises third means for processing data of angular measurements in real time or in predetermined time and controlling the movement of said first means of aiming. Another optic-electronic system with two transmitters on the rear of each vehicle and a passive receiver on the front of each vehicle, where all vehicles determine the position of the preceding vehicle to aid traffic flow. A third optic-electronic system where a single passive tracker determines the position of a single mobile transmitter. With a few angle measurements in time, the position is calculated.
