We are glad to inform you that in order to develop Callisto's sales internationally, the Occitanie region has awarded us an investment grant for the implementation of THE OCCITANIA PASS EXPORT PROJECT.

Due to an expansion of its business, Callisto is seeking to recruit two additional engineers/PHD 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, Cryogenic and Digital Interface equipments for satellite ground stations. Please see current available positions:

Thanks to Western Systems, our representative in India, Callisto participated in the InCAP-2018 Conference on Antenna Propagation held recently in Hyderabad.Our range of products has received a lot of interest from  the visitors.

All the Callisto Team wishes you a Happy, Healthy, and Prosperous 2019!

Callisto has successfully delivered the prototype unit of its new Ultra QRFH Cryogenic receiver fo VLBI to the BKG, VLBI team at Wettzell (Germany). This is a significant milestone for Callisto with a bold move on cryogenic LNA receivers design for wideband operations. This new product presents innovative capabilities for customers all around the world.

As part of the R & T plan for the year 2018 (TC7 technical axis), Callisto is developing for the CNES a Q-band LNA module dedicated to ground station.

After its attendance at ISD ESTEC in Noordwijk on the last 11 & 12th of September, Callisto is continuing its European tour with its participation in European Microwave Week, which provides access to the very latest products, research and initiatives in the microwave sector, on the 25 & 26th September, booth 248, in Madrid, Spain.

On that event Callisto is going to present its cryo feed system project carried out with the partnership of the University of Cantabria Wednesday 25th of September between 5.10 and 5.30 PM.

This paper describes the design of a ground station antenna feed system, that includes feed horn, polarizer, rejection filter, mono-pulse tracking coupler and low noise amplifiers with polarisation switching. The entire feed system assembly is cooled to cryogenic temperature (T < 10 K) in order to maximise the G/T of the ground station antenna (3dB/K gained). The cryogenic cooling system described is fully redundant and this novel design allows one cryocooler to be removed and replaced, while the other cryocooler is still running. The design has been submitted for patent protection.
