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 Celestial Reference Frame (CRF) is a VLBI-only solution based on data until 2015. These differing approaches could potentially lead to […]

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 the Earth Orientation Parameters (EOP) should be estimated with similar accuracy. The conventional International Terrestrial Reference Frame

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 Maria and Flores islands, Açores archipelago). Each
