Successful FAT for the BKG Wettzell
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.
New Contract with BKG AGGO
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.
Callisto wins contract to supply QRFH Ultra Cryogenic Receiver for VLBI to the Bundesamt für Kartographie und Geodäsie (BKG)
Callisto is pleased to announce that it has been awarded a contract by the Bundesamt für Kartographie und Geodäsie to supply QRFH Ultra Cryogenic Receiver for VLBI (Very Long Baseline Interferometry) application. BKG is responsible in Germany as a federal office for tographical basic data, cartography and geodesic reference systems.

Refurbished X band Cryogenic LNAs for radio astronomy, VLBI or Satellite Ground Stations
ESA has recently completed the replacement of all X-band cryo LNAs in its Deep Space Antennas with upgraded models. The original cryo LNAs which were all built and delivered by Callisto in the period 2000 to 2009 are being offered for refurbishment and re-sale. The refurbishment activity will be undertaken by Callisto and will include the replacement of the cryogenic components (cold head, compressor and gas lines), renewal of all vacuum seals and completed RF retest. The systems will be supplied with LNA power supplies, data logging unit and monitoring software. The RF circuits include bandpass filters which could be removed for customers requiring extended RF bandwidth e.g. for radio-astronomy or VLBI. Outline technical details of the equipment are provided in the attached data sheet.
