An optical system for implementing manned vehicle terminal guidance for a soft lunar landing is described. The method utilizes an on-board tracking telescope to establish azimuth and elevation angles. With altitude, this system provides sufficient information for computing lateral vehicle velocity which can be controlled within less than 2 ft/sec, a value not to be exceeded for a safe landing.
