Applications:
Callisto is a leading supplier for Deep Space communications (e.g. space exploration missions to the planets) and radio astronomy. Ultra-low noise performance is achieved by cryo-cooling the electronic RF components of the amplifier circuits.
This ultra-low noise technology can also be used in main stream satellite applications such as Earth Observation where the benefit is a reduction in the size and costs of ground antennas. Callisto's unique cryogenic designs can also reduce maintenance and running costs compared to traditional cryo-systems.

Our clients:
Our clients enjoy a totally dedicated service, with flexibility to adapt to specific requirements. Callisto is a company, recognised and listed as an SME by the European Space Agency.

Callisto has representatives in various countries (North America, India, China and Russia).
