Description:

• Eutelsat-21B will be positioned above the equator at 21.5°E. It will deliver telecommunications services, data services for corporate networks and governmental administrations, and IP access in Europe, North and West Africa, the Middle East and Central Asia.
• Increased capacity for data, video and government services.

Mission details:

• Ariane flight VA210 placed two communications satellites in orbit. The vehicle 566 core stage reached a -956 x 179 km x 7.0 deg path; the ESC-A upper stage raised velocity and lowered inclination to reach a 250 x 35750 km x 2.0 deg transfer orbit, deploying the EUTELSAT 21B satellite, a Thales Alenia Spacebus 4000C3 for Eutelsat SA of Paris and Star One C3, an Orbital Geostar-2.4E for Star One of Rio de Janeiro.
