Astra 1D



Astra 1D was a geostationary spacecraft of the European Space Society that was launched by an Ariane rocket from the Kourou Space Center in French Guiana. It was the last in a series of 4 medium power satellites, and acted primarily as Astra 1B and 1C's backup. It carried four 12.5 GHz BSS transponders that could be combined for HDTV. It was placed in a geostationary orbit at 19.2 deg E (over Zaire).

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.
