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 has already supplied the cryo LNAs sub-systems for the previous two deep space stations, the first (DSA1) located in Western Australia and the second (DSA2) located in Spain.DSA3 is to be built near the small town of Malargue in Mendoza province about 1000 km west of Buenos Aires.

Callisto is building a new cryogenic Test Dewar for the Geodetic Observatory Wettzell (GOW) of the Bundesamt für Kartographie und Geodäsie (BKG) in Germany.

“For any space mission, the ground segment is vital for operating a spacecraft and processing data received from its instrument. Planck is no different, with hardware, software, telecommunication and other operations reaching from Spain to Australia” said Damien Texier, Directorate of Science and Robotic Exploration , at ESAC, Spain.

ESA uses cryogenic LNAs for its deep space telecommunications networkand has decided to upgrade the design of its X-Band cryogenic LNAs with new thermal and RF components to improve performance and long-term reliability.

Callisto has launched a program of development of LNAs to serve the emerging Ka Band SATCOM market.”A number of Ka band communications satellites are ear marked for launch in the coming years to serve European users including HYLAS, KA-SAT and Athena-Fidus” says Steve Rawson Callisto’s CEO. “Callisto is aiming to position itself as a supplier for the ground terminal component market in Ka Band with low noise front end products.We are studying designs of both cooled and uncooled LNAs.”

The objective is to study and investigate solutions for building ground stations for future Deep Space missions for exploration of the outer reaches of the solar system.In the coming decades ESA is planning to send spacecraft to explore the planetary systems of Jupiter and Saturn.In order to communicate with spacecraft at distances of up to 1 billion kms from the Earth, a new generation of Ground Stations will be required with much greater sensitivity in reception and power for transmission.

Due to an expansion of its business, Callisto is seeking to recruit an additional engineer for its engineering team based in our offices in France.This team is engaged in studies related to satellite communications and in the development of specialised RF equipment for satellite ground stations.

Callisto is please to announce the award of a new contract by the CNES.The contract is concerned with the supply in October 2008 of two compact X band (8.0-8.5GHz) cryogenic low noise amplifiers (LNAs) for STEREO satellite ground station.
