One of the critical points concerning radio-astronomy applications regards the power received by the radio telescope, most often extremely faint. Beyond approaches aimed at increasing the collecting area of the radio telescope (at microwave frequenci

This paper describes the design of a ground station antenna feed system, that includes feed horn, polarizer, rejection filter, mono-pulse tracking coupler and low noise amplifiers with polarisation switching. The entire feed system assembly is cooled

Future ground stations will require a high level of operational flexibility and, for this reason, the possibility to adjust their receiving performance (i.e. signal-over-noise) is beneficial. This study presents an approach to achieve this flexibilit

Receivers for radio-astronomical applications, in particular for very long baseline interferometry techniques, where a metal feed is often used to illuminate a reflector antenna, usually operates over wide bandwidths and cooled to low temperatures. I

Space communications between distant spacecraft and the Earth are mainly based on large reflector antennas, such as the 35-m Deep-Space Antennas of the European Space Agency. These provide the required G T and EIRP to existing missions, such as, for

Multi-satellite missions, such as the next generation of METEOSAT geostationary satellites, require a ground station able to support an arbitrary number of satellites that can fly wherever within a pre-determined sky region, called control box. The u
