Radio astronomy with multiband receivers and frequency phase transfer: Scientific perspectives

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 …

The compatibility of DORIS with VGOS

The compatibility of DORIS with VGOS The most precise global geodetic reference frame, the International Terrestrial Reference Frame (ITRF), is based on four space geodesy techniques: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite Systems (GNSS) and the Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) System. All four techniques complement …
