Compact Cryogenic LNAs: Delivery to UTAS

Callisto is proud to announce that another important milestone has been reached for its VLBI products lineup. Three units of our QRFH Compact Cryogenic Receiver have been delivered to the University of Tasmania (UTAS) for its AuScope VLBI Network. The three receivers will be installed at the three AuScope telescopes across the Australia's continent, at Yarragadee (WA), Katherine (NT) and Hobart (TAS) built in 2010.

The story began in 2012 when Callisto started the preliminary studies for a revolutionary cryogenic wideband receiver. In 2013, Callisto and UTAS got in touch to initiate a partnership in this development.

In 2015, convinced by the results obtained so far on the prototype unit, UTAS ordered three production units.

In 2016, UTAS published a press release  on the successful completion of tests of Callisto's revolutionary Receiver. It states "The Callisto receiver is 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".

Finally in 2017, the production of the three units was completed and Callisto delivered them to UTAS. Click here to see our Receiver in the AuScope laboratory.

Callisto can also offer an “Ultra” version of the QRFH receiver (GM cryo-cooler, NT<20K). The prototype of this product is under development at Callisto for the Bundesamt für Kartographie und Geodäsie (BKG). It will be installed on one of the twin-telescope located at Bundesamt für Kartographie und Geodäsie, the BKG Fundamentalstation, of the Wettzel Observatory in Germany.
