Callisto is
pleased to announce the delivery of a Triband Cryogenic LNA System to the
German BKG (Bundesamt für Kartographie und Geodäsie), for use in VLBI radio
astronomy.
Management of Radar Resources for Space Debris Tracking
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 to deliver Cryo LNAs for ESA's Third Deep Space Ground Station (DSA3)
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.
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.
Durée : 4-6 mois.
Le/la titulaire devra être en préparation d'un diplôme Bac+4/Bac+5 dans le domaine de l'électronique ou de l'ingénierie générale.
We are pleased to announce our move to larger premises from the 8th of August 2011, in Villefranche-de-Lauragais (Midi-Pyrené es), 30 min East of Toulouse. The new location will more than double our workshop and laboratory areas.
The move marks continued investment by Callisto for our growth in the satellite communication, radioastronomy and cryo-engineering markets.
This move symbolises an exciting new phase of development for Callisto, explains Steve Rawson, Director. The new premises will enable us to take full advantage of our investments in R+D over the past 2 years as new products come on-line. The additional office, laboratory and workshop areas will allow us to fulfill future production needs, recruit additional engineering staff whilst maintaining the highest practices in support and service provision for our existing clients.
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. This contract is a continuation of a preceding collaboration with the Geodetic Observatory Wettzell (GOW) for building a new cryogenic Test Dewar.
