The Celestia-Callisto team is very pleased to announce that they have been engaged to complete the refurbishment of the Cryogenic RF system of the AGGO (Argentine-German Geodetic Observatory) radio telescope in Pereyra, Argentina.

Celestia Callisto has signed a contract with the German Federal Agency for Cartography and Geodesy (BKG) to supply a new cryogenic receiver for their 20 m. radio telescope located in Wettzell, Germany.

Since the first developments of Cryogenic LNAs in S- and Ka-Band in 1999 for ESA Deep Space Station (DSS) in New Norcia (Australia), Callisto has acquired know-how and develop breakthrough technology to regularly improve reception performance for all ESA Deep Space Stations in New Norcia, Cebreros (Spain) and Malargüe (Argentina).

In partnership with Western Systems, its representative in India, Callisto has supplied S/X Band Ultra Cryoegenic LNAs to ISTRAC since 2008 and the appropriate maintenance service (AMC) as required by the Ultra systems.

In 2018, Callisto was awarded an ESA’s Technology Research Program contract to study and develop an RF sampling demonstrator.

The BKG (Bundesamt für Kartographie und Geodäsie) staff has received a training from Callisto on operation and maintenance of the Triband X,S,Ka cryo-LNA system recently delivered by Callisto. Four people attended this 2-days training course, mainly electrical and mechanical engineers and managers.

We are very happy to announce a successful FAT for our most recent project with Bundesamt für Kartographie und Geodäsie (BKG) to equip one of their antennas at the Wettzell site.

Callisto is proud to announce further work orders with ESOC for 2006 : the provision of a spare S Band Cryogenic LNA for the New Norcia Station. A pair of S Band cryogenic LNAs were designed and built by Callisto as sub-contractor to SED Systems for the DSA1 project in 1999. These LNAs have subsequently been installed and operated in New Norcia since 2000.
