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.
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.
Astra 1A was the first satellite launched and operated by SES, launched in December 1988. During its early days, it was often referred to as the Astra Satellite, as SES only operated one satellite originally. The satellite provided 16 transponders(+6 as rescue) and television coverage to Western Europe from 1989 to 2004. Astra 1A was retired and became derelict in December 2004.
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 1C was a geostationary communications satellite launched in 1993 by SES. The satellite remained in service until 2011 and is now derelict.
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.
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. In March 2015, the satellite has been deactivated and relocated to 113.5° East.
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 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 1L, is one of the Astra geostationary satellites owned and operated by SES, was purchased in June 2003.
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 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 5A was one of the Astra communications satellites owned and operated by SES at the Astra 31.5°E. Launched in 1997 to the 5° East position by NSAB as Sirius 2, operation of the satellite was transferred to SES in April 2008 and the craft renamed and moved to 31.5° East to open up a new orbital position for the company for the development of markets in Central and Eastern Europe and the Middle East.
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.
Astra 1M is a geostationary communications satellite which is operated by SES. It is positioned in geostationary orbit at a longitude of 19.2° East, from where it is used to provide direct to home (DTH) broadcasting to Europe, Africa, and the Middle East.
Astra 1N is one of the Astra communications satellites owned and operated by SES and is positioned at the Astra 19.2°E orbital position. It was launched in 2011 and is the fourth satellite to be built for Astra by Astrium and the 46th SES satellite in orbit, and entered commercial service at 28.2° East on 24 October 2011.
Astra 5B is one of the Astra communications satellites owned and operated by SES. It was launched as SES' 56th satellite in March 2014, to the newest of the Astra orbital positions for direct-to-home (DTH) satellite television, at 31.5° East for DTH, DTT and cable use in Eastern Europe,.
Astra 1P is a Astra communications satellite, built by Thales Alenia Space for owner/operator SES. Launched by SpaceX on 20 June 2024, when it reaches geostationary orbit, the satellite will be positioned in SES's primary European broadcasting slot at 19.2° East, where it will join and replace the Astra 1KR, Astra 1L, Astra 1M, and Astra 1N satellites currently stationed there. Using all-electric thrusters, Astra 1P will take several months to reach geostationary orbit and is expected to begin service in early 2025. Astra 1P is the first Astra satellite to be launched by SpaceX.
