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.

The receiver will be installed on a VLBI telescope located at Bundesamt für Kartographie und Geodäsie, the BKG Fundamentalstation, of the Wettzel Observatory in Germany. It includes a wideband feed horn cooled to cryogenic temperature along with LNAs, and covers the [2.3 - 14] GHz band.

Callisto will be attending the TTC 2016 and the ISD 2016.

The University of Tasmania (UTAS - part of AuScope) has just published a press release on the successful completion of tests of Callisto's revolutionary Cryo-LNA receiver for VLBI antenna.

The receivers which will be installed at the three AuScope telescopes are particularly important for AuScope as the technology used is designed to be highly reliable and low maintenance - an important consideration when operating telescopes in remote locations.

Australia’s contribution to the VLBI network includes three radio telescopes across the continent, at Yarragadee (WA), Katherine (NT) and Hobart (TAS). The network is operated by UTAS as part of AuScope - UTAS is the only university in the world to operate a continent-wide array of radio telescopes.

Callisto is pleased to announce that an important milestone has been passed at the end of 2015 for its new “Compact”, zero maintenance cryogenic receiver including the Caltech designed QRFH feed: the first light on a VLBI telescope!

Callisto is pleased to announce the successful delivery of a new cryogenic test Dewar system for testing of various types of small components including RF. This system is cryogen-free (no liquids), operates under high vacuum and uses a GM-type refrigerator (cryocooler).

The Ka Band Cryo Feed Critical Design has been accepted by ESA and Callisto will start the manufacture of this receiver early in 2016.

The G/T of ESA DSA can be improved by 2.9dB at Ka Band.

Callisto is pleased to announce that it has been awarded a contract by Morehead State University, Kentucky, USA to supply an X Band Cryo Compact Low Noise Amplifier (LNA). 

Callisto is pleased to announce that it has been awarded a contract by
Thales  Alenia  Space,  Toulouse  to  supply  Low  Noise  Amplifiers  (LNAs)
operating in the 25.5 to 27 GHz Band for the Meteosat Third Generation
(MTG) project. 

In order to improve the G/T of ESA Deep Space Antennas (DSA) by 2dB, a new cryogenic receiver will be developed in collaboration with the University of Cantabria.
