Very Long Baseline Interferometry (VLBI)

Over its 40-year history of development and operation, the space geodetic technique called very long baseline interferometry (VLBI) has provided an unprecedented record of the motions of the solid Earth. VLBI is unique in its ability to define an inertial reference frame and to measure the Earth's orientation in this frame.
