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 Madrid), and on the islands […]

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

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

Advancing Solar System Dynamics Investigations with Calibrated Precision Doppler Tracking Planetary gravitation and solar system dynamics investigations rely on precision Doppler tracking of spacecraft. In the most sensitive Doppler measurements carried out by the NASA/JPL Deep Space Network (Allan deviations ~3×10-15 at 1000 s integration time), the unmodeled time-dependent motion of the large (34 m)
