Abstract
In order to demonstrate the feasibility of eventually using radio interferometry techniques to measure tectonic motion, a series of interferometry experiments has been conducted between two antennas at the Goldstone Deep Space Communications Complex. The primary objective of these experiments was to develop independent-station instrumentation capable of making three-dimensional baseline measurements with an accuracy of a few centimeters. To meet this objective, phase-stable instrumentation was developed to precisely measure the time delay by means of two-channel bandwidth synthesis. Delay measurements produced by this instrumentation lead to three-dimensional baseline measurements with a precision of 2-5 cm for the components of a 16-km baseline.
