Satellite Use:

Poised to be the largest satellite in the SES fleet, SES-4 at 338*east replacing NSS-7, will enhance what is already the largest neighborhood in the Atlantic. SES-4 will be a hybrid satellite featuring high powered C-band coverage and incremental global capacity which is ideal for video distribution, government and VSAT services. The satellite's Ku-band payload will provide enhanced coverage and capacity across Europe, the Middle East, Africa, Western Africa and Latin America. SES-4 will bring a substantial increase in the total capacity available at 338* 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 powered regional Ku-band beams will provide service to Europe, the Middle East, West Africa, North America and South America with extensive cross-strapping between C- and Ku-band transponders providing enhanced connectivity.

Satellite Statistics:

__Largest, most powerful satellite in the SES Fleet
__52 C-band transponders
__72 Ku-band transponders
__Planned orbital location: 338 degrees East longitude
__Anticipated service life: 15 years

Mission Profile:

The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the SES-4 satellite on board. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the SES-4 satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geostationary transfer orbit. Separation of the SES-4 satellite is scheduled to occur approximately 9 hours, 12 minutes after liftoff.

Target Orbit at Separation:
Perigee: 3,714 km
Apogee: 35,786 km
Inclination: 24.6 degrees

Spacecraft Separation:

Approximately 9 hours, 12 minutes after liftoff

Mas que las fotos de un lanzamiento comercial, parecen las fotos de la previa de montar una palombo en el Radio Club...
Y a juzgar por la franela de "..adelantamo un dí­a.... no no posponemo 25 dí­a...!!" se me huele que hay cierta infiltración argenta en esa corpo. :ugeek:
