摘要: Very-long-baseline interferometry (VLBI) techniques have already been used to determine the vector separations between antennas thousands of kilometers apart within 2 m and directions extragalactic radio sources 0.1", track an artificial satellite earth Apollo Lunar Rover on surface moon. The relative locations Surface Experiment Package (ALSEP) transmitters lunar are being measured 1 m, moon's libration is 1" selenocentric arc. Attempts under way measure solar gravitational deflection waves more accurately than previously possible, by means VLBI. A wide variety scientific problems attacked VLBI techniques, which may soon be two orders magnitude accurate at present.
