The present paper explains the principles of using very-long-baseline rf interferometry and laser rangefinding to the moon to obtain geodesic and astronomical data. The first method involves simultaneous observation of extragalactic point radio sources (quasars) by two radio telescopes several thousand kilometers apart on the earth's surface. The second method uses optical corner reflectors set up on the moon's surface for making accurate distance determinations. Such measurements are of prime importance for establishing a geocentric coordinate system and a scale of distances and for studying the motion of the earth's poles. The paper discusses the feasibility of using very-long-baseline rf interferometry and laser rangefinding for checking and refining existing astronomical and geodesic networks.
