Astra 1C was the third satellite launched by the Société Européenne des Satellites (SES), now SES Astra. It is the oldest Astra satellite still in operation. It carries almost entirely analogue television services aimed at Germany, with one transponder in use for digital services. Only 13 transponders are still in an operational state as of 2005. ...more on Wikipedia about "Astra 1C"
Astra 1D was the fourth, and under original plans, last Société Européenne des Satellites (SES), now SES Astra. It was launched to Astra's original solitary operational position at 19.2E, and was intended as an in-orbit spare for Astra's 1A, 1B and 1C. However, demand for additional capacity for both British and German television channels, plus the extension of the the receivable segment of the Ku band beyond 250Mhz on most consumer equipment led to the satellite becoming regularly used, and the launch of a further 4 Astra 1 satellites. The launch of these later craft returned 1D to a role as a "troubleshooter" for the Astra fleet. ...more on Wikipedia about "Astra 1D"
