Thor 5, also known as Thor 2R is a Norwegian communications satellite. It was successfully launched for Telenor atop an International Launch Services Proton-M/Briz-M carrier rocket, at 11:34 GMT on 11 February 2008.It is based on the STAR-2 satellite bus, and was constructed by Orbital Sciences Corporation. It carries 24 Ku band transponders, to provide direct-to-home television broadcasting. After launch, the Briz-M upper stage placed Thor 5 directly into a geosynchronous orbit, eliminating the need for orbital raising manoeuvres and making the spacecraft able to save weight by carrying less fuel. It is positioned at a longitude of 1° West.
Norway, officially the Kingdom of Norway, is a Nordic country in Northwestern Europe whose territory comprises of the western and northernmost portion of the Scandinavian Peninsula; the remote island of Jan Mayen and the archipelago of Svalbard are also part of the Kingdom of Norway. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land.
A communications satellite is an artificial satellite that relays and amplifies radio telecommunications 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. There are 2,134 communications satellites in Earth's orbit, used by both private and government organizations. Many are in geostationary orbit 22,236 miles (35,785 km) above the equator, so that the satellite appears stationary at the same point in the sky, so the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track it.
Telenor ASA is a Norwegian multinational telecommunications company headquartered at Fornebu in Bærum, close to Oslo. It is one of the world's largest mobile telecommunications companies with operations worldwide, focus in Scandinavia, Eastern Europe and Asia. It has extensive broadband and TV distribution operations in four Nordic countries, and a 10-year-old research and business line for Machine-to-Machine technology. Telenor owns networks in 13 countries, and has operations in 29 countries.
Proton is an expendable launch system used for both commercial and Russian government space launches. The first Proton rocket was launched in 1965. Modern versions of the launch system are still in use as of 2019, making it one of the most successful heavy boosters in the history of spaceflight. All Protons are built at the Khrunichev State Research and Production Space Center factory in Moscow, transported to the Baikonur Cosmodrome, brought to the launch pad horizontally, and raised into vertical position for launch.

It is positioned in geostationary orbit at a longitude of 100.5° East of the Greenwich Meridian, where it replaced the AsiaSat 2 spacecraft. It is used to provide fixed satellite services, including broadcasting, telephone and broadband VSAT communications, to Asia and the Pacific Ocean.
The Briz-K, Briz-KM and Briz-M are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M, Angara A5 or Rokot, one of Russia's smaller launchers.
The Proton-M, (Протон-М) GRAU index 8K82M or 8K82KM, is an expendable Russian heavy-lift launch vehicle derived from the Soviet-developed Proton. It is built by Khrunichev, and launched from sites 81 and 200 at the Baikonur Cosmodrome in Kazakhstan. Commercial launches are marketed by International Launch Services (ILS), and generally use Site 200/39. The first Proton-M launch occurred on 7 April 2001.
AMC-14 is a communications satellite. Initially owned by SES Americom, AMC-14 was designed to be placed in geostationary orbit, following launch on a Proton rocket. Built by Lockheed Martin and based on the A2100 satellite bus, AMC-14 was to have been located at 61.5° west longitude for DISH Network service.
Inmarsat-4 F3 is a communications I-4 satellite operated by the British satellite operator Inmarsat. It was launched into a geosynchronous orbit at 22:43 GMT on 18 August 2008, by a Proton-M/Briz-M Enhanced carrier rocket. It is currently located at 97.65° West longitude, providing coverage of the Americas. It entered service on 7 January 2009.
Gorizont 33, also known as Gorizont 45L was a Russian communications satellite operated by Kosmicheskiya Svyaz. It was the last satellite to be launched as part of the Gorizont constellation. Constructed by NPO Prikladnoi Mekhaniki, it was based on the KAUR-3 satellite bus. Its launch was contracted by Khrunichev, using a Proton-K/Briz-M carrier rocket. The launch occurred at 02:59 GMT on 6 June 2000 from Site 81/24 at the Baikonur Cosmodrome.
Nimiq 5 is a Canadian communications satellite, operated by Telesat Canada as part of its Nimiq fleet of satellites. It is positioned in geostationary orbit at a longitude of 72.7° West of the Greenwich Meridian. As of July 2015, EchoStar Corporation leases the satellite's entire capacity to provide High Definition television direct-to-home broadcasting for Dish Network Corporation. When accessed using a multi-satellite receiver such as the VIP722k and a multi-satellite dish/LNB combo, such as the Dish-300, Dish-500, or Dish-Turbo 1000.4, the satellite is (incorrectly) referred to by the on-screen diagnostics as Echostar 72W.
SES-1 is a geostationary communications satellite which is operated by SES World Skies. It was originally ordered by SES Americom as a ground spare for AMC-5R, however in April 2008 a decision was made to launch it, and it was named AMC-1R. It was subsequently renamed AMC-4R, and finally SES-1 after SES Americom merged with SES New Skies to form SES World Skies. It was the third World Skies satellite to be launched following the merger, but the first to carry the new SES designation. SES-1 operates in geostationary orbit, and is intended to be located at a longitude of 101 degrees West, where it will replace the AMC-2 and AMC-4 satellites, and be used broadcast high-definition television to very small aperture terminals in the United States.
