The Ariane 4 was an expendable space launch system, developed by the Centre national d'études spatiales (CNES), the French space agency, for the European Space Agency (ESA). It was manufactured by ArianeGroup and marketed by Arianespace. Since its first flight on 15 June 1988 until the final flight on 15 February 2003, it attained 113 successful launches out of 116 total launches.
Aérospatiale was a French state-owned aerospace manufacturer that built both civilian and military aircraft, rockets and satellites. It was originally known as Société nationale industrielle aérospatiale (SNIAS). Its head office was in the 16th arrondissement of Paris. The name was changed to Aérospatiale during 1970.
Alcatel Space has built Atlantic Bird 2 (26 channels in Ku Band for this Spacebus 3000 B2 Satellite) for Eutelsat. By meeting a rapid delivery schedule (16 month on ground delivery), which is made possible by an advanced production policy for the Spacebus-3000B2 platform, Alcatel Space has enabled Eutelsat to meet crucial back-up service requirements while expanding digital and multimedia services. In addition to the on-ground delivery of Atlantic Bird 2, Alcatel Space's prime contract with Eutelsat provides for the satellite's launch campaign, as well support for its operations and mission analysis.
Geosynchronous OrbitTürksat 2A, a.k.a. Eurasiasat 1, was a Turkish communications satellite as part of a project to form an instant network with two geosynchronous satellites that is supervised by the companies Türksat A.Ş. in Turkey and Eurasiasat SAM in Monaco.
Geosynchronous OrbitOriginally ordered by Orion Network Systems as Orion 2, the contract was later terminated. It was then bought by Eutelsat as spare satellite, called RESSAT, which was later renamed Eutelsat W1 as a replacement satellite compatible with their previously-launched W2 and W3 spacecraft. Eutelsat subsequently decided to launch W1 in September 2000. Located at the 10 degrees East position, the satellite serves a full range of applications that include that include business communications, Internet-based services and television transmission. It has 28 channels, 20 of which provide coverage of Europe, North Africa, the Middle East and central Asia via a fixed widebeam, with the remaining eight connected to a steerable spotbeam, to address new markets in geographical areas outside the widebeam coverage area (notably southern Africa). Services can be simultaneously provided within both coverages.
Geostationary OrbitJointly owned by Singapore Telecom (SingTel) and Chunghwa Telecom of Taiwan, the ST 1 satellite system provides telecommunications and direct-to-home broadcast services to most of Asia, up to 16 high-power Ku-band transponders over India, south-east Asia and Taiwan, and 14 C-band transponders for coverage from western India and Pakistan to Borneo, the Philippines and south-eastern China. The ST 1 satellite was launched in August 1998. Two ground control stations are located in Seletar (Singapore) and Taipei (Taiwan).
Geostationary OrbitWith the launch of Nilesat 101 on 28 April 1998, delivering more than 100 digital TV channels as well as radio and multimedia services to more than five million homes over the whole of North Africa from Morocco to the Persian Gulf, Egypt became the first African country to have its own direct TV broadcast satellite. A second satellite, Nilesat 102, was launched in 2000, and the Nilesat system now broadcasts more than 150 digital TV channels and provides additional services such as data transmission, turbo internet and multicasting applications. BSAT-1a and -1b replaced the two BS-3 spacecraft used for DBS services, including Hi-Vision test broadcasts, by NHK, WOWOW, and others. Hughes selected the Ariane rocket as the launch vehicle for the BSAT-1 spacecraft. BSAT-1a was launched 16 April 1997 from the Guiana Space Center in Kourou, French Guiana. BSAT-1b was also launched from Kourou on 28 April 1998. The two satellites are located at 110 degrees East longitude.
Geostationary OrbitThree of the most powerful broadcast satellites ever launched that are capable of direct-to-home (DTH) service are providing DTH programming to millions of consumers of PanAmSat. They were designed and built by Space Systems/Loral (SS/L). PanAmSat-6 (PAS-6) provides quality digital television to customers in South America.
Geostationary OrbitThe Intelsat VIII-VIII/A series has been designed to meet the needs of Intelsat users throughout the system for improved C-band coverage and service. These spacecraft will incorporate six-fold C-band frequency reuse, two-fold frequency reuse of expanded C-band capacity, and the highest C-band power level ever for an Intelsat satellite. Consequently, Intelsat VIII will provide significantly more C-band capacity for public switched telephony and Intelsat Business Service, better quality for video services, and encourage new international VSAT applications.

Geostationary OrbitSO (Infrared Space Observatory) was a infrared space telescope designed and operated by the European Space Agency (ESA), in cooperation with ISAS and NASA. ISO was designed to study infrared light at wavelengths of 2.5 to 240 micrometers to provide detailed infrared properties of selected Galactic and extragalactic sources.
Elliptical OrbitTwo Space Systems/Loral (SS/L) satellites with the highest capacity of any commercial payloads in space were delivered on orbit in 1995 and 1996 and are now providing a variety of fixed and mobile domestic communications services to customers throughout Japan. These satellites, N-STAR-a and -b, replace the service of the SS/L CS satellites, which have now exceeded their expected lifetimes, and will also provide significant new services, which range from providing alternate routes for telephony, to emergency communications, to marine and terrestrial mobile services, and ISDN.
