Abstract

The operation of the GI2T two-telescope inteferometer, a precursor to the Optical Very Large Array (OVLA), is described. The GI2T, consisting of two 1.5-meter telescopes, is beginning to provide high-resolution data on stellar envelopes. It is also used to test components for the 27-telescope OVLA. Prototypes of the metrology system, the compact telescopes, and a walking robot are under construction. These developments are preparatory to the construction of the OVLA and its moon-based version with three to 33 telescopes. Following tests of tracking and vibration performance, the prototype 1.5-m telescope will operate with the GI2T.
