Badr-4 (a.k.a. Arabsat 4B) is an EADS Astrium-built [1] communications satellite operated by Arabsat, launched 8 November 2006 on a Proton-M/Briz-M rocket. [2] It provides fixed satellite communications services in C- and Ku-bands from the 26° East orbital position. [3]
The satellite is based on the Eurostar E2000+ platform. Its payload was supplied by Alcatel Alenia Space. The Badr-4-payload consists of 28 active channels in Ku band (16 in BSS and 12 in FSS). Payload power is about 6 kW. The satellite has two 2.5 m deployable antennas and one 1.35 m top floor antenna.
Due to success of the satellite, Arabsat let another agreement for an upgraded version of Badr-4 communication satellite: in June 2006, Arabsat gave the contract to EADS Astrium for construction of Badr-6, a high-power broadcast satellite to cover the Middle East and Africa. [1] Badr-6 was launched by an Ariane 5 on 7 July 2008. [4]
This satellite carries 32 transponders in Ku band/FSS & Ku band/BSS. The spacecraft utilizes Astrium's Eurostar E2000+ platform to carry 22 C-band transponders (including eight 52 W moderate power transponders) and 12 Ku band transponders. [5] [6]
Hot Bird is a group of satellites operated by Eutelsat, located at 13°E over the equator and with a transmitting footprint over Asia, Europe, North Africa, Americas and the Middle East.
The Nimiq satellites are a Canadian fleet of geostationary telecommunications satellites owned by Telesat and used by satellite television providers including Bell Satellite TV and EchoStar. 'Nimiq' is an Inuit word used for an object or a force which binds things together. A contest in 1998 was held to choose the name of these satellites. The contest drew over 36,000 entries. Sheila Rogers, a physiotherapist from Nepean, Ontario, submitted the winning name.
The Arab Satellite Communications Organization is a communications satellite operator in the Arab World, headquartered in the city of Riyadh, Saudi Arabia. Arabsat was created to deliver satellite-based, public and private telecommunications services to the Arab States, in accordance with International Standards. With 21 member countries, the organization plays a vital role of enhancing communications in the Arab World.
Skynet 5A is the first in a series of new-generation Skynet military communications satellites, used by the British Ministry of Defence. It was launched aboard an Ariane 5 carrier rocket at 22:03 GMT on 11 March 2007.
Türksat is the name of a series of Turkish communications satellites operated or projected by the state-owned Türksat A.Ş.
JCSAT-11, was a geostationary communications satellite ordered by JSAT Corporation which was designed and manufactured by Lockheed Martin on the A2100 platform. The satellite was designated to be used as an on-orbit, but was lost on launch failure.
HYLAS is a British satellite in geostationary orbit. HYLAS, which is an acronym for Highly Adaptable Satellite, is a communications satellite and was launched by the European Ariane 5 launch vehicle from the Guyana Space Centre at Kourou in French Guiana. It is located at the orbital location of 33.5 degrees west and will provide new and innovative services including High Definition Television (HDTV) and interactive satellite delivered broadband services. The satellite will help address the issue of poor broadband coverage in many parts of Europe which have less developed ground infrastructure.
Alphabus is a family of heavy geostationary communications satellites developed by a joint venture between Thales Alenia Space and EADS Astrium Satellites in France, with support of the Centre national d'études spatiales (CNES), the French space agency and the European Space Agency (ESA).
Nimiq-4 is a Canadian geosynchronous communications satellite. It was launched aboard a Proton-M / Briz-M launch vehicle at 21:48:00 UTC on 19 September 2008. It was positioned at 82.0° West longitude, and operated by Telesat Canada.
The DirecTV satellite fleet is a group of communications satellites located at various geostationary orbits that DirecTV uses for their satellite television service and HughesNet internet service. The "DirecTV" prefix in their names has been changed to "T".
Hot Bird 13C, formerly Hot Bird 9, is a communications satellite operated by Eutelsat, launched 20 December 2008 aboard an Ariane 5ECA carrier rocket along with the Eutelsat W2M spacecraft. It was built by EADS Astrium, based on a Eurostar E3000 satellite bus. It was positioned in geosynchronous orbit at 13°E. After in-orbit testing it will provide communications services to Asia, Europe, Americas, North Africa and the Middle East, with 64 NATO J-band transponders.
Eurostar is a satellite bus made by Airbus Defence and Space (formerly Astrium, and before 1994, British Aerospace, and Matra Marconi Space which has been used for a series of spacecraft providing telecommunications services in geosynchronous orbit. More than 70 Eurostar satellites have been ordered to date, of which more than 55 have been successfully launched since October 1990 and have proven highly reliable in operational service. In December 2013, the Eurostar satellites accumulated 500 years of successful operations in orbit. The Eurostar spacecraft series is designed for a variety of telecommunications needs including fixed services and broadcast, mobile services, broadband and secured communications.
Arabsat-5A is a Saudi Arabian communications satellite operated by Arabsat. It will be used to provide television, internet and telephone services to Arabia, Africa and Europe.
Chollian, also known as Communication, Ocean and Meteorological Satellite 1 (COMS-1), was a South Korean satellite which was launched on 26 June 2010 and began operations on 1 April 2011. It was operated by the Korea Aerospace Research Institute, who used it for communication, oceanography, and meteorological observation.
Yahsat 1A is a communications satellite constructed by EADS Astrium and Thales Alenia Space for Al Yah Satellite Communications Company (Yahsat). It was launched in April 2011 from Arianespace's Guiana Space Centre in Kourou French Guiana in a dual payload launch with Intelsat New Dawn atop an Ariane 5 ECA rocket. Yahsat Y1A is based on the Eurostar E3000 satellite bus and had a launch mass of about 6000 kg. It is intended to provide Ku, Ka and C-band communications to the Middle East, Africa, Europe and Southwest Asia. It is in geosynchronous orbit at 52.5 degrees East.

INSAT-2D was an Indian communications satellite. Launched on 4 June 1997, and similar to INSAT-2C, INSAT-2D went out of order on October 4, 1997, because of a power inconsistency problem and was later replaced by INSAT-2DT, an in-orbit satellite which was previously known as ARABSAT-1C. The main aim of the satellite was improved communication. In the INSAT-2 series, INSAT-2D was the fourth consecutive communication satellite. The satellite was launched using an Ariane 4 rocket from French Guiana.
