Spaceway-3 is a communications satellite which was launched in August 2007. The third satellite in the Spaceway series, it includes a Ka-band communications payload. [1] It is used by Hughes Network Systems to provide broadband Internet Protocol network service.
In March 2007, shortly after the failure of a Sea Launch rocket launch in January 2007, Hughes Network Systems switched launch of Spaceway-3 from a Zenit-3SL rocket to an Ariane 5 launch vehicle. [2] [3]
Spaceway-3 was launched 14 August 2007 on an Ariane 5 launch vehicle with BSAT-3a. [4] It lifted off at 23:44 UTC from ELA-3 of the Centre Spatial Guyanais. Five hours and 46 minutes later, signals from the spacecraft were successfully received at a ground station in Hartebeesthoek, South Africa. [5]
Ariane 5 is a heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). A direct successor system, Ariane 6, is in development.
Arianespace SA is a multinational company founded in 1980 as the world's first commercial launch service provider. It undertakes the operation and marketing of the Ariane programme. The company offers a number of different launch vehicles: the heavy-lift Ariane 5 for dual launches to geostationary transfer orbit, the Soyuz-2 as a medium-lift alternative, and the solid-fueled Vega for lighter payloads.
The Guiana Space Centre is a French and European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Operational since 1968, it is particularly suitable as a location for a spaceport. It fulfills the two major geographical requirements of such a site:
Skynet is a family of military communications satellites, now operated by Airbus Defence and Space on behalf of the United Kingdom's Ministry of Defence, which provide strategic communication services to the three branches of the British Armed Forces and to NATO forces engaged on coalition tasks. The Skynet 1 to 4 series were operated by the Royal Air Force until 2003, and subsequently operated with Skynet 5 by Paradigm Secure Communications until October 2012 when the organisation was rebranded to Astrium Services.
Sea Launch is a multinational spacecraft launch service that used a mobile maritime launch platform for equatorial launches of commercial payloads on specialized Zenit-3SL rockets through 2014.
Spaceway-1 was a part of AT&T's constellation of direct broadcast satellites. The satellite was launched via a Zenit-3SL rocket from Sea Launch's Odyssey equatorial platform on 26 April 2005. Its operational position was in geosynchronous orbit 35,800 kilometres (22,200 mi) above the equator at 102.8° West longitude. Spaceway-1 was a Boeing 702-model satellite with a 12-year life expectancy. It provided high-definition television to DirecTV customers with its Ka-band communications payload. DirecTV did not make use of the broadband capabilities on Spaceway-1 even though it was originally built by Boeing for this purpose.
This is a list of the satellites operated by Optus, an Australian telecommunications company. The satellite communications facility is located at Belrose on Sydney's Northern Beaches. Optus' satellites are divided into 4 classes A, B, C and D. As of April 2014 it owns and operates Optus B3, Optus C1, Optus D1, Optus D2 and Optus D3. Optus A1, Optus A2, Optus A3 and Optus B1 satellites have been retired. Optus has the largest network of satellites in Australia and New Zealand.
Spaceway-2 is part of AT&T's constellation of direct broadcast satellites. The satellite was launched via an Arianespace Ariane 5 ECA rocket from Kourou, French Guiana on 16 November 2005. Its operational position is in geosynchronous orbit 35,800 kilometres (22,200 mi) above the equator at 99.2° West longitude. Spaceway-2 is a Boeing 702-model satellite with a 12-year life expectancy. It is expected to support high-definition television to DirecTV customers with its Ka-band communications payload. Although Spaceway-2 was originally built by Boeing to be used for broadband Internet access via Hughes Network Systems, it has been retrofitted to deliver HD local channels to numerous markets nationwide.
Launch Services Alliance is a "back-up" launch service provider. It is a joint venture between the multinational aerospace company Arianespace and Japanese conglomerate Mitsubishi Heavy Industries; initially, the American aerospace firm Boeing Launch Services was involved as well.
Brasilsat B1 is a Brazilian communications satellite launched on August 10, 1994, by an Ariane rocket model 44L at Guiana Space Centre which is located in Kourou, French Guiana.
ELA-3, short for Ensemble de Lancement Ariane 3, is a launch pad and associated facilities at the Centre Spatial Guyanais in French Guiana. ELA-3 is operated by Arianespace as part of the expendable launch system for Ariane 5 rockets. As of December 2019, 106 launches have been carried out from it, the first of which occurred on 4 June 1996.
The Broadcasting Satellite System Corporation (B-SAT) is a Japanese corporation established in April 1993 to procure, manage and lease transponders on communications satellites. Its largest stockholder, owning 49.9%, is NHK, the Japan Broadcasting Corporation. In 1994, it was ranked by Space News as the world's 19th largest fixed satellite operator.
The AT&T satellite fleet is a group of communications satellites located at various geostationary orbits that AT&T uses for the DirecTV satellite television service and HughesNet internet service. The "DirecTV" prefix in their names has been changed to "T".
BSAT-3a, is a geostationary communications satellite operated by Broadcasting Satellite System Corporation (B-SAT) which was designed and manufactured by Lockheed Martin on the A2100 platform. It is stationed on the 110,0° East orbital slot with its companion BSAT-3b and BSAT-3c from where they provide redundant high definition direct television broadcasting across Japan.
BSAT-3b, is a geostationary communications satellite operated by Broadcasting Satellite System Corporation (B-SAT) which was designed and manufactured by Lockheed Martin on the A2100 platform. It is stationed on the 110.0° East orbital slot along its companion BSAT-3a and BSAT-3c from where they provide redundant high definition direct television broadcasting across Japan.
BSAT-3c, also known as JCSAT-110R, is a geostationary communications satellite operated by Broadcasting Satellite System Corporation (B-SAT) and SKY Perfect JSAT (JSAT) which was designed and manufactured by Lockheed Martin on the A2100 platform.
BSAT-4a is a geostationary communications satellite ordered by Broadcasting Satellite System Corporation (BSAT) and designed and manufactured by SSL on the SSL 1300 platform. It is expected to be stationed on the 110.0° East orbital slot for direct television broadcasting of 4K and 8K Ultra HD resolutions.
The JSAT constellation is a communication and broadcasting satellite constellation formerly operated by JSAT Corporation and currently by SKY Perfect JSAT Group. It has become the most important commercial constellation in Japan, and fifth in the world. It has practically amalgamated all private satellite operators in Japan, with only B-SAT left as a local competitor.
Ariane flight VA253 is a planned rocket launch conducted by multinational launch service provider Arianespace.
BSAT-4b, is a geostationary communications satellite ordered by B-SAT and designed and manufactured by SSL on the SSL 1300 platform. It is expected to be stationed on the 110° East orbital slot for direct television broadcasting of 4K and 8K Ultra HD resolutions.
