RAEGE: the Spanish-Portuguese Infrastructure of Geodetic Stations This contribution will show the current status of the joint Spanish-Portuguese infrastructure for Space Geodesy called RAEGE, which stands for Red Atlántica de Estaciones Geodinámicas y Espaciales. This infrastructure will consist of four space geodesy stations, two in Spain (Yebes and Gran Canaria) and two in Portugal (Santa

VLBI-based assessment of the consistency of the conventional EOP series and the terrestrial reference frames The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) envisages stringent accuracy goals for the International Terrestrial Reference Frame (ITRF) realization in terms of position (1 mm) and velocity (0.1 mm/year). These requirements entail that the
VLBI for Geodesy: Fundamentals, Operation, Products & Applications The RAEGE network (Portuguese-Spanish acronym for Atlantic Network of Geodynamic and Space Stations) is a project resulting from the cooperation between the National Geographic Institute of Spain (IGN) and the Government of Azores. It is a unique project at a geodetic and geodynamic level, in which it

Analysis of VGOS sessions: Evaluation of performance with different software VGOS (VLBI Global Observation System) is a new generation VLBI system. It has been developed since 2005 and it is based on the so-called broadband delay that uses four or more frequency bands. High data rate observations are taken by fast-slewing antennas, smaller than those

New Cable Delay Measurement System for VGOS Stations This paper presents the new cable delay measurement system (CDMS) designed at Yebes Observatory (IGN, Spain), which is required for the VLBI Global Observing System (VGOS) stations. This system measures the phase difference between the 5 MHz reference signal from the hydrogen maser and the 5 MHz

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)
