The payload consisted of 18 eclipse protected transponders, plus six spares with 63W TWTA 10.75-10.95 GHz FSS (&12.5 GHz BSS) down Ku-band European beams in 250 MHz band adjacent (below) to Astra 1C, 26 MHz bandwidth, eirp 50 dBW min, orthogonal polarization, operating in the FSS range. It had a design life of 15 year.
