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.

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.

At the recent Industry Space Days 2018 Celestia Technology Group companies C-STS, Callisto,  and TTI  collaborated on their exhibition presence across the two-day event. The Group presented the new Modems programs for multi-constellations, multi-functional datalink, an innovative e-Scan BFN antenna for multi-satellite tracking and the GaN SSPA and LNA Cryogenics for the next generation of satellite communications.

ISD 2018 had large industrial participation of more than 200 exhibitors and 1000 companies attending including a high number of SMEs, indicating a growth of smaller companies in the space technologies sector. Conference sessions at the event covered Cubesat, additive manufacturing and PLATO missions’ procurements.

As part of a French consortium, Callisto joins the SKA Organization

SKA? The acronym stands for the largest radio telescope ever imagined. This international project of low and medium frequency radio telescopes plans to build  with a collector area of ​​one square kilometer. Coordinated by the CNRS, the SKA-France consortium has just become the 12th member of SKA-O, which is the  organization responsible for the feasibility study and design of the telescope project. The SKA-France consortium  includes five research organizations (the CNRS, the universities of Bordeaux and Orléans, the observatories of Paris and the Côte d'Azur) as well as seven industrialists (Air Liquide, ATOS-Bull, Callisto, CNIM, Kalray, TAS). Several French laboratories have participated in technical preparatory studies for the project, some since the beginning in 2012. Once operational, the SKA, or "Square Kilometer Array", should allow to perceive the traces of the creation of the Universe 15 billions years ago.
