Astra 1C

Astra 1C was a geostationary communications satellites launched in 1993 by the Société Européenne des Satellites (SES), now SES Astra. The commsat remained in service until 2011 and is now derelict.

Astra 1C was the third communications satellite placed in orbit by SES, and was originally deployed at the Astra 19.2°E orbital position.^[2]

The satellite was intended to be replaced in 2002, along with Astra 1B, by Astra 1K but this satellite failed to reach its intended orbit. It was eventually relieved of its remaining television/radio payloads by Astra 1KR in 2006.^[3]

In November 2006, prior to the launch of Astra 1L to the 19.2°E position, Astra 1C was placed in an inclined orbit and moved first to 2.0°E for tests, and then in February 2007 to 4.6°E, notionally part of the Astra 5°E cluster of satellites^[4] but largely unused.

After November 2008, the satellite operated back at 2.0°E,^[5] in inclined orbit. On November 2, 2011 the satellite was taken out of use as Eutelsat, the rightholder for the 3° allocation, came on air with Eutelsat 3A and current rules ask for a minimum of 2° separation. In the summer of 2014, the satellite was moved to 73°W, close to SES' AMC-6 satellite,^[6] to 1.2°W,^[7] to 152°W,^[8] to 40°W next to SES-6,^[9] to 91°E in January 2015^[10] and continuously moving west by approximately 5.2° per day to reach 164°E at the end of 2015^[11]
