Precision Geodesy via Radio Interferometry

Science, 1972
Very-long-baseline interferometry experiments, involving observations of extragalactic radio sources, were performed in 1969 to determine the vector separations between antenna sites in Massachusetts and West Virginia. The 845.130-kilometer baseline was estimated from two separate experiments.

Radio-frequency low-coherence interferometry

Optics Letters, 2014
A method for retrieving low-coherence interferograms, based on the use of a microwave photonics filter, is proposed and demonstrated. The method is equivalent to the double-interferometer technique, with the scanning interferometer replaced by an analog fiber-optics link and the visibility recorded as the amplitude of its radio-frequency (RF) response.

Radio interferometry

Reviews of Geophysics, 1987
The potential of Very Long Baseline Interferometry (VLBI) to provide important new geodetic, geophysical, and astrometric information has long been recognized, and the past four years have seen a realization of that potential. VLBI measurements have been used to determine the sizes, shapes, rotations, flexures and tectonic deformations of networks of ...

Radio interferometry

Reviews of Geophysics, 1983
In the previous Quadrennial Report, Clark [1979c] concluded that, after slightly more than one decade of development and refinement, the technique of Very Long Baseline Interferometry (VLBI) had “come of age.” However, by the close of 1978, only the most tentative first steps had been taken by the geodetic community toward the deployment and operation ...
