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
IGN Yebes Observatory Technology Development Center 2021–2022 Report The main technical developments of the Yebes Observatory (IGN, Spain) in 2021 and 2022 related to geodetic VLBI are introduced. J. A. Lopez-Pérez[1], C. Albo-Castaño[1], R. Amils-Samalot[1], L. Barbas-Calvo[1], M. Bautista-Durán[1], F. J. Beltrán-Martínez[1], M. Díez-González[1], J. D. Gallego-Puyol[1], P.García-Carreño[1], A. García-Castellano[1],
A Simulation Study Exploring The Capabilities Of The RAEGE Frame Within The IVS And Beyond RAEGE commenced in 2011 with a Memorandum of Understanding between the Governments of Azores and Spain to set up a Very Long Baseline Interferometry VLBI observing network consisting of four antennas situated at Yebes (near
Single-dish observations of methanol masers at 6.67 and 12.2 GHz with a 13.2 m VGOS radio telescope in the Mid-Atlantic The RAEGE network (Portuguese/Spanish acronym for Atlantic Network of Geodynamic and Space Stations) is a cooperation project between the National Geographic Institute of Spain and the Regional Government of the
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)
Assessing The Consistency Of The Conventional Reference Frames (Terrestrial And Celestial) And Their Impact On Estimated EOP Using VLBI-Based Data The conventional International Terrestrial Reference Frame (ITRF) is based on the combination of solutions from several space geodetic techniques, including observations until the end of 2020, and incorporates updated data
RAEGE Capabilities: A Simulation Study RAEGE is a project resulting from the cooperation between the National Geographic Institute of Spain (IGN Spain) and the Government of Azores. It is aimed to set up four multi-technique stations: two in Spain (Yebes and Gran Canaria) and two in Azores (Flores and Santa
Performance of the VGOS radio telescope with as-built feed and geometry using electromagnetic simulation This paper reports on electromagnetic simulations performed of the as-built VGOS (VLBI Global Observing System) 13.2-metre Radio Telescope at the Hartebeesthoek Radio Astronomy Observatory (HartRAO). Specifically, the telescope performance with a measured quadruple-ridge flared horn (QRFH)
Alicante IVS Analysis Center Very Long Baseline Interferometry (VLBI) is a highly accurate method, used since the 1970s in astrophysics as well as in geodesy. It contributes significantly to the global international terrestrial reference frame (ITRF) and is the only space geodetic technique able to realize the international celestial reference
