A Tri-Band Cooled Receiver for Geodetic VLBI This paper shows a simultaneous tri-band (S: 2.2–2.7 GHz, X: 7.5–9 GHz and Ka: 28–33 GHz) low-noise cryogenic receiver for geodetic Very Long Baseline Interferometry (geo-VLBI) which has been developed at Yebes Observatory laboratories in Spain. A special feature is that the whole

Spectrum Management for the VGOS Spectrum management for the VLBI Global Observing System (VGOS) is an important task to keep radio frequency interference as absent as possible from observation sites. Protection can only be granted, if national and international authorities are made aware of the activities and operations at VLBI
New Designs in VGOS Front-ends in Yebes Observatory The Yebes Observatory has designed and built five VGOS compliant receivers (2-14 GHz bandwidth) for their own radio telescopes and for other European IVS partners under contract or agreement since 2015. Although such receivers are successfully working in their respective sites, we
Consistency of VLBI estimates in the CONT17 campaign As part of its observing program, the International VLBI Service for Geodesy and Astrometry (IVS) arranges special observation campaigns of continuous Very Long Baseline Interferometry (VLBI) known as CONT campaigns. The last CONT campaign (CONT17) was carried out by the end of
The current status of RAEGE When complete, the Red Atlántica de Estaciones Geodinámicas y Espaciales (RAEGE) will be composed of four VGOS radio-telescopes, two in Spain (Yebes and Gran Canaria) and two in Portugal (Santa María and Flores islands). The Yebes VGOS radio-telescope is fully operational and integrated in the
Polarization calibration techniques for the new-generation VLBI The calibration and analysis of polarization observations in very long baseline interferometry (VLBI) requires the use of specific algorithms that suffer from several limitations, closely related to assumptions in the data properties that may not hold in observations taken with new-generation VLBI equipment.
