SES-4 (NSS-14) at 22° West
|Manufacturer:||Space Systems/Loral (SS/L)|
|Launch vehicle:||Proton M/Breeze|
|Expected lifetime:||15+ Years|
SES-4 is a hybrid satellite featuring 52 × 36 MHz equivalent C-band transponders and 72 × 36 MHz equivalent Ku-band transponders, a substantial increase in the total capacity available at 338 degrees East The state-of-the-art spacecraft has been specifically designed for its orbital location, with C-Band beams serving the eastern hemisphere of Europe/Africa, full America’s coverage as well as a global beam to support mobile and maritime customers. Four high power, regional Ku-Band beams will provide service to Europe/Middle-East, West Africa, North America and South America with extensive cross-strapping between C- and Ku-band transponders providing enhanced connectivity. Government applications will benefit from sophisticated command encryption.
The satellite is based on the Space Systems/Loral’s SSL-1300 bus and is equipped with an ion propulsion system ensuring a minimum life of at least 15 years in orbit. With a launch weight of 5,800 kgs, SES-4 satellite is compatible with all relevant launch vehicle providers. SES NEW SKIES deployed SES-4 over the Atlantic Ocean region at 338° East, enabling the incumbent NSS-7 satellite to move to a new orbital position.
SES-4 was launched on July 10th, 2012, on a Proton M booster rocket operated by launch operator ILS.
