Technical hitch delays SES-4 satellite

Editor ©RapidTVNews | 29-12-2011

Problems with the avionics system in the upper stage of the ILS Proton launch vehicle have pegged back the take-off of the new SES-4 satellite by 25 days.

Only hours before take-off from the Baikonur Cosmodrome in Kazakhstan in the early hours of 27 December, ILS informed SES that engineers has received an anomalous telemetry reading on the Breeze M upper stage during pre-flight testing. The additional 25 days is needed due to the destacking and replacement of the affected avionics unit of the satellite which was built by Space Systems/Loral. ILS assured SES that the vehicle and satellite remain in a safe configuration at the launch site.
Positioned at 338° East, SES-4 is set to be the largest satellite in the SES fleet, replacing the NSS-7 and enhancing what is said to be already the largest neighbourhood in the Atlantic.
The hybrid satellite will feature C-band coverage and incremental global capacity for video distribution and its Ku-band payload will provide enhanced coverage and capacity across Europe, the Middle East, Africa, Western Africa and Latin America. Indeed the spacecraft has been specifically designed for its orbital location, with 52 C-band transponders and 72 Ku-band transponders.
