Callisto was pleased to welcome members of the maintenance teams from ESA Deep Space Antennas to our offices in Labastide for training on cryogenic low noise amplifiers systems. Two consecutive courses of one week duration each were organised in the first half of December. In this period four engineers from Cebreros and four engineers from New Norcia deep space stations were trained.

Dans le cadre d'un projet de recherche et développement, Callisto recherche un stagiaire capable :

·        d'étudier le marché des récepteurs satellites maritimes.

·        de réaliser l'état de l'art des modules de refroidissement à élément Peltier disponibles actuellement sur le marché.

·        d'évaluer les performances RF de l'amplificateur faible bruit refroidit compte tenu des technologies dont nous disposons.

·        et finalement d'entrevoir la conception d'un prototype de test.

 

 

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 .

We are currently seeking to recruit an additional engineer for our client based in Germany.

 

In addition to having a University degree (or equivalent) in the relevant discipline, ideal candidates shall have 5 years experience in administration and troubleshooting of networks in distributed systems. The experience shall have been made in an operational or production environment.

Callisto is please to announce the award of two new contracts work orders by the European Space Agency at the beginning of 2008.  The contracts are concerned with the development of new cryogenic low noise amplifiers (LNAs) for satellite ground stations. 

 

 

The final presentation of the results of a study into the use of the 26 GHz Frequency band for ESA ground stations was held at ESOC, Darmstadt, 31st October 2007. The presentation was given Callisto as prime contractor for the study supported representatives from the University of Pavia and ERA Technology. The feasibility study investigated the upgrade of ESA Deep-Space Antenna network to support the newly allocated frequency band for Space Research missions in the range 25.5 to 27 GHz.

Callisto will participate in the Fourth International Workshop on Tracking, Telemetry and Command System for Ground and Space Application, TTC 2007, which will be held from the 11th to the 14th of September 07 at ESOC, in Darmstadt, Germany.
