Callisto is proud to announce the award of a new study for the European Space Agency.

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.  The solutions which will be investigated will include the option of building a very large antenna greater than 70m diameter, or building an array of smaller antennas which can be combined together.   The study will address not only the engineering challenges associated with the various options, but also the cost, with a clear goal of identifying the most cost effective approach.

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. 

The responsibilities of the selected candidate will typically include :  undertaking research and studies in ground to satellite communications problems, developing system level designs of ground stations, definition and specification of antennas and RF circuits, simulation of communications channels, analysis of signal processing elements, preparation of engineering drawings, preparation of reports & documentation.

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.
