Astra 1C was a geostationary communications satellite launched in 1993 by SES . The satellite remained in service until 2011 and is now derelict .

History [ edit ]

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° 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] to 40° West next to SES-6 , [9] to 91° East in January 2015 [10] and continuously moving west by approximately 5.2° per day to reach 164° East at the end of 2015. [11]
