SES-5 (also known as Astra 4B and Sirius 5) is a commercial geostationary communication satellite operated by SES S.A. It was launched on 9 July 2012. The launch was arranged by International Launch Services (ILS).
In October 2008, SES Sirius AB of Sweden (then 90% owned by SES and prior to 2003 called Nordic Satellite AB) ordered the Sirius 5 satellite from Space Systems/Loral. [2] Following full acquisition by SES in 2010, SES Sirius was renamed SES Astra (a subsidiary of SES) and the satellite renamed Astra 4B. [3] In 2011, SES Astra was merged back into SES and the satellite renamed SES-5. [4] [5]
It was constructed by Space Systems/Loral, and is based on the SSL 1300 satellite bus. It carries 24 C-band and 36 Ku-band transponders. It covers Atlantic Ocean, Sub-Saharan Africa, North Africa, Europe, Middle East. [4] [6]
SES 5 is also carrying a hosted payload L-band navigation terminal for the executive commission of the 27-nation European Union. The terminal operated as part of the European Geostationary Navigation Overlay Service (EGNOS) system, which provides verification of Global Positioning System (GPS) navigation signals through the use of satellites in geostationary orbit. [7]
Sirius 5 was the original name of the SES-5 satellite. SES-5 that was launched on 9 July 2012, at 18:38:30 UTC from Baikonur Cosmodrome, Site 81/24 and is now co-located with Astra 4A (Sirius 4) at 5° East. This satellite provides a similar European and African coverage as Astra 4A.
Astra is the brand name for a number of 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, in eastern Luxembourg. The name is also used to describe the pan-European broadcasting system provided by these satellites, the channels carried on them, and even the reception equipment.
SES Sirius, formerly called Nordic Satellite AB (NSAB) was the owner and operator of the two Sirius satellites, which provide the Nordic countries and the Baltic states, with TV, radio, data and communications solutions. The company is today entirely owned and controlled by SES and has no independent existence.
SES S.A. is a Luxembourgish satellite telecommunications network provider supplying video and data connectivity worldwide to broadcasters, content and internet service providers, mobile and fixed network operators, governments and institutions.
Sirius was a constellation of communications satellites operated at 5.0° East in geostationary orbit (GEO) by NSAB. They carried digital satellite television to the countries of Scandinavia, Baltic states, Eastern Europe and Africa, including the Viasat pay TV system, along with several pay TV packages for Eastern Europe, the TopTV package for Africa, a number of Ukrainian channels and the national Latvian and Lithuanian channel service free-to-air.
Astra 1E is one of the Astra communications satellites in geostationary orbit owned and operated by SES. It was launched in October 1995 to the Astra 19.2°E orbital slot initially to provide digital television and radio for direct-to-home (DTH) across Europe.
Astra 1F is one of the Astra communications satellites in geostationary orbit owned and operated by SES. It was launched in April 1996 to the Astra 19.2°E orbital slot initially to provide digital television and radio for direct-to-home (DTH) across Europe.
AsiaSat 5 is a Hong Kong communications satellite, which is operated by the Hong Kong based Asia Satellite Telecommunications Company (AsiaSat). It is positioned in geostationary orbit at a longitude of 100.5° East of the Greenwich Meridian, where it replaced the AsiaSat 2 satellite. It is used to provide fixed satellite services, including broadcasting, telephone and broadband very small aperture terminal (VSAT) communications, to Asia and the Pacific Ocean region.
Astra 1L, is one of the Astra geostationary satellites owned and operated by SES, was purchased in June 2003.
SES Broadband is a two-way satellite broadband Internet service available across Europe, which launched in March 2007, and uses the Astra series of geostationary satellites.
Astra 5°E is the name for the Astra communications satellites co-located at the 5° east position in the Clarke Belt which are owned and operated by SES based in Betzdorf, Luxembourg. 5° east is one of the major TV satellite positions serving Europe.
Astra 5A was one of the Astra communications satellites owned and operated by SES at the Astra 31.5°E. Launched in 1997 to the 5° East position by NSAB as Sirius 2, operation of the satellite was transferred to SES in April 2008 and the craft renamed and moved to 31.5° East to open up a new orbital position for the company for the development of markets in Eastern Europe and the Middle East.
Astra 1M is a geostationary communications satellite which is operated by SES. It is positioned in geostationary orbit at a longitude of 19.2° East, from where it is used to provide direct to home (DTH) broadcasting to Europe, Africa, and the Middle East.
O3b Networks Ltd. was a network communications service provider building and operating a medium Earth orbit (MEO) satellite constellation primarily intended to provide voice and data communications to mobile operators and Internet service providers. O3b Networks became a wholly owned subsidiary of SES S.A. in 2016 and the operator name was subsequently dropped in favour of SES Networks, a division of SES. The satellites themselves, now part of the SES fleet, continue to use the O3b name.
Thor is a family of satellites designed, launched and tested by Hughes Space and Communications for British Satellite Broadcasting (BSB), and were used for Britain's Direct Broadcast Service. Thor is owned by Telenor. Marcopolo 1 launched on 27 August 1989 on the 187th launch of a Delta rocket, and Marcopolo 2 launched on 17 August 1990, on a Delta II rocket. Marcopolo I had the Hughes designation HS376.
AsiaSat 7 is a Hong Kong communications satellite, which is operated by the Hong Kong based Asia Satellite Telecommunications Company (AsiaSat). It is positioned in geostationary orbit at a longitude of 105° East of the Greenwich Meridian, where it serves as a back-up for the AsiaSat 5 satellite and replaced AsiaSat 3S. It is used to provide fixed satellite services, including broadcasting, telephone and broadband very small aperture terminal (VSAT) communications, to Asia and the Pacific Ocean region.
Astra 2F is one of the Astra communications satellites owned and operated by SES S.A., launched in September 2012 to the Astra 28.2°E orbital position. The satellite provides free-to-air and encrypted direct-to-home (DTH) digital television and satellite broadband services for Europe and Africa.
Astra 5B is one of the Astra communications satellites owned and operated by SES. It was launched as SES' 56th satellite in March 2014, to the newest of the Astra orbital positions for direct-to-home (DTH) satellite television, at 31.5° East for DTH, DTT and cable use in Eastern Europe,.
O3b mPOWER is a communications satellite system currently under construction and, as of May 2022, scheduled to begin launching in the fourth quarter of 2022. Owned and operated by SES, O3b mPOWER initially comprises 11 high-throughput and low-latency satellites in a medium Earth orbit (MEO), along with ground infrastructure and intelligent software, to provide multiple terabits of global broadband connectivity for applications including cellular backhaul to remote rural locations and simultaneous international IP trunking.
AMC-12 is an American geostationary communications satellite that was launched by a Proton-M / Briz-M launch vehicle at 02:27:32 UTC on 3 February 2005.
