The SES-17 satellite was successfully launched into space onboard an Ariane 5 launcher operated by Arianespace from the Europe’s Spaceport in Kourou on October 23rd 2021.
Built by Thales Alenia Space, SES-17 marks an important milestone in satellite technology as the first Ka-band geostationary satellite to embark a fully digital payload powered the most powerful digital transparent processor (DTP) ever placed in orbit.
This satellite is equipped with the first ever Mechanically pumped Loop (MPL) to be mounted on a telecommunication satellite!
The MPL is made of a network of pipes and a mechanical pump, which circulates a refrigerant fluid to collect heat wherever it is created and transport it to the radiators. This makes it possible to maximise use of the available surface inside the satellite, to accommodate the repeaters required for large Very High Throughput Satellite missions.
EHP is proud to have contributed to the development and to have supplied this new generation of heat exchangers.
