A persistent scatterer experiment using corner reflectors has been set up to validate the quality of InSAR Envisat/ERS-2 phase observations. The validation is performed by means of independent precise leveling observations of corner reflector motion in time, and comparison with respect to InSAR observables. The estimated precision of the InSAR double-differenced phase measurements is 2.8mm (vertical) for "zero-gyro" ERS-2 data and 1.6mm for Envisat. An analysis of an integration of corner reflectors and neighboring "natural" persistent scatterers is also presented.
