Eutelsat Quantum is a European re-programmable telecommunications satellite equipped with Ku-band payload, developed in a public-private partnership between the European Space Agency (ESA), Eutelsat and Airbus Defence and Space.[5]

It had a launch mass of approximately 3,461 kilograms (7,630 lb) and a design lifetime of 15 years.[4]

Orbit
Altitude evolution of the four objects (satellites, SYLDA and upper stage).

The target orbit was a geosynchronous transfer orbit with an apogee altitude of 250 kilometres (160 mi) and a perigee altitude of 35,726 kilometres (22,199 mi), at an inclination of 3°.[4]

Flight

The flight was successfully launched from the ELA-3 launch pad in Kourou, Centre Spatial Guyanais during the night of 30 to 31 July 2021, at the very start of the launch window (which spanned from 21:00 to 00:30).[2] The mission was planned to last 36 minutes and 24 seconds.[4]
