SES-8, a hybrid Ku- and Ka-band spacecraft, is the sixth STAR™ satellite ordered by SES WORLD SKIES. The satellite is based on Orbital’s Enhanced STAR 2.4 bus, and will carry 24 active Ku-band transponders of 36 or 54 Mhz capacity switchable among 33 channels and two beams. Certain channels in each beam are cross-strapped to multiple frequency bands, enabling flexibility for new services. In the addition, the spacecraft features a Ka-band payload. The spacecraft will generate approximately five kilowatts of payload power and will feature two 2.5 x 2.7 meter super elliptical deployable reflectors and a 1.45 meter fixed, nadir antenna.
