InSAR datum connection using GNSS-augmented radar transponders

Deformation estimates from Interferometric Synthetic<br/>Aperture Radar (InSAR) are relative: they form a ‘free’<br/>network referred to an arbitrary datum, e.g. by assuming a reference<br/>point in the image to be stable. However, some applications<br/>require ‘absolute’ InSAR estimates, i.e. expressed in<br/>a well-defined terrestrial...
