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
RAEGE Project: Status, Analysis Endeavours, and Future Prospects RAEGE (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
RAEGE Santa Maria: Station overview The RAEGE station of Santa Maria is part of the RAEGE network (Atlantic Network of Geodynamic and Space Stations), a cooperation project established between the National Geographic Institute of Spain (IGN) and the Regional Government of the Azores. It is a unique project at a
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
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
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
Geodetic data analysis of VGOS experiments Very Long Baseline Interferometry (VLBI) serves as one of the common geodetic methods to define the global reference frames and monitor Earth’s orientation variations. The technical upgrade of the VLBI method known as the VLBI Global Observing System (VGOS) includes a critical re-design of
Satellite Laser Ranging Satellite Laser Ranging (SLR) is a space geodetic technique that consists in the measurement of the time-of-flight of laser photons emitted from ground stations to retroreflectors onboard satellites in orbit. Accurate and precise observations, at the level of a few millimetres, of the instantaneous ranges to the
The Atlantic Network of Geodynamic and Space Stations (RAEGE) This paper shows the current status of the Red Atlántica de Estaciones Geodinámicas y Espaciales (RAEGE), a joint Spanish-Portuguese infrastructure of geodetic stations. When complete, it will be composed of four VGOS (VLBI Global Observing System) radio-telescopes, two in Spain (Yebes
