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° East position, Astra 1C was placed in an inclined orbit and moved first to 2.0° East for tests, and then in February 2007 to 4.6° East, notionally part of the Astra 5°E cluster of satellites[4] but largely unused.
After November 2008, the satellite operated back at 2.0° East,[5] in an inclined orbit. On 2 November 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° West, close to SES' AMC-6 satellite,[6] to 1.2° West,[7] to 152° West,[8] and to 40° West next to SES-6.[9] From January 2015, it was continuously moving west by approximately 5.2° per day.[10]
