Callisto supplied  the Cryogenic & Ambient LNAs at 26 GHZ GHz band for the ESA Snowbear project : a Svalbard ground station for wide-band  earth observation data reception.

Due to congestion in the Earth Exploration Service (EES) at X-Band (8.0-8.4 GHz) and  (7.75-7.9 GHz) used today by most Earth Observation satellites for payload  data downlinks and the increase in required downlink data rates, ESA has embarked on the  technology preparation for the exploitation of the 26 GHz band by future Earth Observation  missions. The Agency will use this band operationally for the first time in a polar orbit mission  for the EUMETSAT Metop-SG spacecrafts (first Launch in 2021), currently under development by ESA. The purpose of the SNOWBEAR project (Svalbard grouNd StatiOn for Wide Band Earth observation dAta Reception) is to de-risk the introduction of the new 26 GHz band taking advantage of the outcome of a number of activities already carried out by the ESA Ground Station Engineering team (OPS-GS) as part of the 26 GHz Technology  Roadmap and use them on a pre-operational scenario. 

For this project, Callisto provided a 26GHz dual channel Cryogenic  and Ambient LNAs. As a result, this allowed to obtain a G/T  > 37.2 dB/K for the Cryogenic LNA and  a G/T  > 35.3 dB/K for the Ambient Temperature LNA (considering 5 degree elevation and 0.25 Cumulative Distribution).

Callisto will attend the 6th TSS, the international gathering for space stakeholders between 26-28th June, booth B19, at Centre de Congrès Pierre Baudis in Toulouse.

Callisto is pleased to announce that it has been awarded a contract by the National Radio Astronomy Observatory (NRAO) in the USA for the next generation Very Large Array (ngVLA) project.

Since the first developments of Cryogenic LNA in S- and Ka-Band in 1999 for ESA Deep Space Station (DSS) in New Norcia (Australia) followed by 2 other Cryogenic LNAs in X- and Ka-Bands for ESA DSS in Cebreros (Spain) and Malargüe (Argentina), Callisto has acquired a know-how and continues to improve its products with disruptive innovations.

Today, Callisto is proud to announce the development of a new X-Band cryo-cooled feed prototype for ESA DSS.

Callisto is pleased to announce its attendance as an exhibitor at the Satellite 2018 (SATShow), which will be held from 12th to 15th of March at the Convention Center (801 Mt. Vernon Place NW) in Washington, USA.

The Callisto Days 2017 was held on December 8-9, 2017 at Callisto's premises, in Villefranche de Lauragais (close to Toulouse), France.

Callisto is pleased to announce our attendance at the International Microwave & RF Conference 2017 which will be held December 11-13, 2017 at the Hyatt Regency in Ahmedabad, India. We will be represented by our agent for the Indian Market: Western Systems. You are welcome at our booth no 39.

Callisto is pleased to announce its attendance at the Space Tech Expo Europe, which will be held from 24th to 26th of October at the Messe Bremen in Bremen, Germany.

Callisto is pleased to announce its attendance at the 6th International VLBI Workshop, which will be held from 9th to 11th of October at the Area della Ricerca in Bologna, Italy.
