Astra 1C
Astra 1C was a geostationary communications satellite launched in 1993 by the Société Européenne des Satellites (SES), now SES Astra. The satellite remained in service until 2011 and is now derelict. History Astra 1C was the third communications satellite placed in orbit by SES, and was originally deployed at the Astra 19.2°E orbital position. 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. 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 but largely unused. After November 2008, the satellite operated back at 2.0° East, in an inclined orbit. On 2 November 2011, the satellite was tak ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Astra 1D
Astra 1D is a geostationary communications satellite launched in 1994 by the Société Européenne des Satellites (SES). , the craft remains in service for occasional use. Astra 1D was the fourth, and under original plans, last Astra communications satellite from SES. It was launched to SES' original solitary operational position at 19.2° East, and was intended as an in-orbit spare for Astra's Astra 1A, 1B and 1C and to carry digital TV transmissions. However, development of digital reception equipment in Europe was not sufficiently advanced for Astra 1D to be SES' first digital satellite (the later Astra 1E fulfilled that role) and demand for additional capacity for both British and German television channels led to 12 of the satellite's transponders being leased to broadcast analogue TV channels before the satellite had been launched. History After launch to 19.2° East, Astra 1D served two periods as a spare at the Astra 28.2°E position colocated with Astra 2A, for s ...

Inclined Orbit
A satellite is said to occupy an inclined orbit around Earth if the orbit exhibits an angle other than 0° to the equatorial plane. This angle is called the orbit's inclination. A planet is said to have an inclined orbit around the Sun if it has an angle other than 0° to the ecliptic plane. Types of inclined orbits Geosynchronous orbits A geosynchronous orbit is an inclined orbit with an altitude of that completes one revolution every sidereal day tracing out a small figure-eight shape in the sky. A geostationary orbit is a special case of geosynchronous orbit with no inclination, and therefore no apparent movement across the sky from a fixed observation point on the Earth's surface. Due to their inherent instability, geostationary orbits will eventually become inclined if they are not corrected using thrusters. At the end of the satellite's lifetime, when fuel approaches depletion, satellite operators may decide to omit these expensive manoeuvres to correct inclination a ...

Astra (satellite)
Astra is the brand name for a number of geostationary satellite, geostationary communication satellites, both individually and as a group, which are owned and operated by SES S.A., a global satellite operator based in Betzdorf, Luxembourg, Betzdorf, in eastern Luxembourg. The name is also used to describe the pan-European broadcasting system provided by these satellites, the channel (broadcasting), channels carried on them, and even the reception equipment. At the time of the launch of the first Astra satellite, Astra 1A in 1988, the satellite's operator was known as Société Européenne des Satellites. In 2001 SES Astra, a newly formed subsidiary of SES, operated the Astra satellites and in September 2011, SES Astra was consolidated back into the parent company, which by this time also operated other satellite families such as SES Americom, AMC, and SES World Skies, NSS.

Astra 1KR
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. The satellite launched to 3.4° East for testing, before moving to Astra 19.2°E, where it replaced Astra 1B, which was effectively decommissioned, and Astra 1C, which was then elderly and running beneath full capacity. It was expected to also replace Astra 2C, which was under-utilised, and to allow that satellite to return to Astra 28.2°E to join Astra 2A / 2B / 2D to provide additional capacity. However, SES stated that Astra 1L would replace Astra 2C. The first signals from the satellite at 19.2° East were direct replacements for four transponders on the failing Astra 1E.
