Radio astronomy with multiband receivers and frequency phase transfer: Scientific perspectives The technique of frequency phase transfer (FPT), enabled by multiband receivers with shared optical path (SOP), is set to become a true backbone of VLBI operations at frequencies above 22 GHz. The FPT has been successfully implemented at the Korean VLBI Network (KVN), while …

Assessment of DTRF2014 and ITRF2014 by Satellite Laser Ranging Satellite laser ranging orbital solutions, using observations of satellites LAGEOS and LAGEOS-2 collected from 2000 to 2017, were used to test the performance of two reference frame realisations, ITRF2014 and DTRF2014.We compare the post-fit residuals from solutions where only initial conditions and orbit parameters were solved …
