Abstract

Experiments for differential interferometry were conducted over 16 months using corner reflectors. Baseline analysis based on the ephemeris data shows possible 17 pairs of good quality. Analysis of the first pair demonstrates a capability of detecting displacement with accuracy less than 1 cm. Phase variations which may be due to the atmosphere and another reason brought by surface features are observed
