Astra 1C was a geostationary communications satellite launched in 1993 by SES. The satellite 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° 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]
Astra is the brand name for a number of geostationary communication satellites, both individually and as a group, which are owned and operated by SES, a global satellite operator based in Betzdorf, in eastern Luxembourg. The name is also used to describe the pan-European broadcasting system provided by these satellites, the channels carried on them, and even the reception equipment.
Eutelsat 133 West A is a Eutelsat operated Eurobird satellite, used primarily for digital television. It was launched in March 2001, and after a short period testing at 33°E, joined Eutelsat 2F4 at 28.5°E in the Clarke Belt, just within the range of satellite dishes pointed at SES' Astra 2 satellites at 28.2° east. It moved to 33° east and joined Eutelsat 33B in July 2015. Then it was moved to 133° west.
Astra 2D was one of the Astra communications satellites owned and operated by SES and located at 28.2° East in the geostationary orbit until June 2015. It was a Hughes Space and Communications HS-376HP satellite bus and was launched from the Centre Spatial Guyanais in December 2000 to join Astra 2A and Astra 2B at 28.2° East, where it remained for its active life.
SES S.A., trading as SES is a Luxembourgish satellite telecommunications network provider supplying video and data connectivity worldwide to broadcasters, content and internet service providers, mobile and fixed network operators, governments and institutions.
Astra 1B was the second of the Astra communications satellites launched and operated by SES to add extra capacity to the satellite television services from 19.2° East, serving Germany, the United Kingdom and Ireland.
Astra 1D is a geostationary communications satellite launched in 1994 by the Société Européenne des Satellites (SES). As of August 2012, the craft remains in service for occasional use.
Canal 24 Horas is a Spanish free-to-air television channel owned and operated by Televisión Española (TVE), the television division of state-owned public broadcaster Radiotelevisión Española (RTVE). It is the corporation's all-news television channel, and is known for its 24-hour rolling news service and its live coverage of breaking news.
Astra 1E is one of the Astra communications satellites in geostationary orbit owned and operated by SES. It was launched in October 1995 to the Astra 19.2°E orbital slot initially to provide digital television and radio for direct-to-home (DTH) across Europe.
Astra 2A is one of the Astra communications satellites owned by SES. Launched in 1998 into the 28.2° East orbital position, half its expected end-of-life capacity of 28 transponders were pre-booked by BSkyB, who utilised it to launch their new Sky Digital service.
Astra 2B is one of the Astra communications satellites owned and operated by SES. Launched in September 2000 to join Astra 2A at the Astra 28.2°E orbital position providing digital television and radio broadcast services to the United Kingdom and Ireland, the satellite has also served at the Astra 19.2°E and the Astra 31.5°E positions.
Astra 2C is one of the Astra communications satellites owned and operated by SES. Designed to join Astra 2A and Astra 2B at the Astra 28.2°E orbital position providing digital television and radio broadcast services to the United Kingdom and Ireland, the satellite was first used after launch in 2001 at 19.2° East for pan-European coverage.
Astra 3A is one of the Astra communications satellites owned and operated by SES, launched in March 2002 to the Astra 23.5°E orbital position to provide digital television and radio for direct to home (DTH) and cable, multimedia and interactive services, corporate networks, and occasional and other business services to Europe.
Astra 1KR is one of the Astra geostationary satellites owned and operated by SES, was purchased in June 2003. It was launched on 20 April 2006, 20:27:00 UTC as a replacement for Astra 1K, which failed to reach orbit on launch in November 2002. The launch of Astra 1KR was the first attempted by SES since the Astra 1K failure.
Astra 1K was a communications satellite manufactured by Alcatel Space for SES. When it was launched on 25 November 2002, it was the largest civilian communications satellite ever launched, with a mass of 5,250 kg (11,570 lb). Intended to replace the Astra 1B satellite and provide backup for 1A, 1C and 1D at the Astra 19.2°E orbital position, the Blok DM3 upper stage of the Proton-K launch vehicle failed to function properly, leaving the satellite in an unusable parking orbit.
Astra 28.2°E is the name for the group of Astra communications satellites co-located at the 28.2° East position in the Clarke Belt that are owned and operated by SES based in Betzdorf, Luxembourg. It is one of the major TV satellite positions serving Europe.
Astra 5°E is the name for the Astra communications satellites co-located at the 5° east position in the Clarke Belt which are owned and operated by SES based in Betzdorf, Luxembourg. 5° east is one of the major TV satellite positions serving Europe.
Astra 23.5°E is a group of Astra communications satellites co-located at the 23.5° east position in the Clarke Belt owned and operated by SES based in Betzdorf, Luxembourg. 23.5° east is one of the major TV satellite positions serving Europe.
Astra 31.5°E is the name for the group of Astra communications satellites co-located at the 31.5° east position in the Clarke Belt owned and operated by SES based in Betzdorf, Luxembourg. 31.5° east is SES' newest orbital location serving Europe.
Astra 19.2°E is the name for the group of Astra communications satellites co-located at the 19.2°East orbital position in the Clarke Belt that are owned and operated by SES based in Betzdorf, Luxembourg.
