Radio Frequency Interference (RFI) • RFI originates from man-made signals generated in the antenna electronics or by external sources (e.g., satellites, cell-phones, radio and TV stations. The geodetic VLBI concept uses two or more radio telescopes to observe numerous extragalactic radio sources distributed across the skies, mostly quasars or radio galaxies.

In geodetic VLBI. NASA's Space Geodesy Project (SGP) is a new initiative that started at the end of FY SGP is part of the Earth Science Decadal and the National Research Council study 'Precise Geodetic.

Out of the five sources, only one (SDSS J–) shows a confidently detected compact VLBI core at both frequencies. The other four sources are marginally detected at GHz only. achieved on the m in /5.
