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 Azores. The project will build
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

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 and models. In contrast, the
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 Maria). These stations will stablish

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) and with actual surfaces and
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 frame (ICRF) as well as

VLBI-Based Assessment Of The Consistency Of The Conventional EOP Series And The Reference Frames (Terrestrial And Celestial) The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) envisages stringent goals for the International Terrestrial Reference Frame (ITRF) realization in terms of accuracy (1 mm) and precision (0.1 mm/year). These requirements entail that
RAEGE – An Atlantic Network of Space Geodetic Stations The RAEGE project (Portugues/Spanish acronym for Atlantic Network of Geodynamic and Space Stations) is a cooperation project established between the Government of Spain and the Regional Government of the Azores that intends the construction and operation of 4 fundamental space geodetic stations: 2 in Spain (Yebes
