This biennial event is the premier international forum for the presentation, discussion, and dissemination of the latest research and development activities related to all aspects of cryocooling.

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 delivered the critical cryo-LNA sub-system comprising three X-Band amplifiers three Ka-Band amplifiers to SED Systems, the prime contractor for the DSA3 project. Callisto had 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 being built near the small town of Malargüe in Mendoza province about 1000 km west of Buenos Aires.

Tens of thousands of debris are expected in the near future in the most critical Low Earth Orbit (LEO) regimes, hence representing a serious threat for European space assets. In the frame of the Space Situational Awareness Preliminary Programme of the European Space Agency, the design for a ground-based phased array radar – aimed at debris detection and tracking – has been proposed. Track-while-Scan (TwS) survey is combined with Active Tracking (AT) tasks in order to achieve the required performance. A managing strategy for TwS/AT radar resources is analysed versus the accuracy requirements dictated by collision warning services.

Callisto recently carried out a study on the cryogenics options for the Square Kilometre Array (SKA) Organization, which aims to develop the largest radio telescope in the World (see www.skatelescope.org) in order to study a wide range of scientific phenomena, including many related to the origins and early development of the Universe.

As part of an ongoing support contract to INMARSAT, Callisto provided manpower support to a LEOP being performed by Telespazio for the Apstar-7 satellite. Callisto provided support at the INMARSAT spacecraft control centre in London for the use of two of the Inmarsat ground stations (Bejing,China and Lake Cowichan, Canada) and the Inmarsat communication network. The launch was successful and the injection was as predicted and the ground stations provided support up until the drift phase.

Dans le but de proposer de nouveaux services et un nouveau produit à ses clients, Callisto recherche une personne pour un travail de développement d’alimentations électriques pour des systèmes cryogéniques.

Callisto is pleased to announce that it has recently been awarded a new contract to provide a Multi-Band cryogenic Dewar for installation on a VLBI telescope located at Bundesamt fuer Kartographie und Geodaesie (BKG), Fundamentalstation, Wettzell.
