s, and will have a lifetime of about 15 years (up to 2024).
W7 will be the most powerful spacecraft in the fleet of Eutelsat.
The craft can be configured to have up to 70 Ku band transponders during its 15-year mission.
It will be colocated with Eutelsat's W4 satellite at the 36 degrees East position.
Digital broadcasting and direct-to-home video services will be beamed to customers in Russia and sub-Saharan Africa using W7.
The new satellite will replace all the capacity on the SESAT 1 platform, which is being redeployed to another location after nearly 10 years of operations.
W7's communications payload is connected to five downlink beams for Europe, Russia, Africa, the Middle East, and Central Asia.
