SES Sirius
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. The 2004 SES Annual Report states that 16.4 million homes received broadcast and broadband services from the Sirius system, 1.5 million from the satellites directly and another 14.9 million from cable networks distributing content via Sirius. History In 1982 the governments of Sweden and Norway formed NSAB as part of a wide-ranging partnership for the purpose of "telecommunication satellite cooperation". In 1989 the two governments agreed to end their partnership, the Swedish government assumed full ownership with the acquisition of Norway's 15% share. On April 2, 1989 NSAB's first satellite, the Aérospatiale built Tele-X, was launched on an Ariane 2 rocket from French ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sirius (satellite)
Sirius was a constellation of communications satellites operated at 5.0° East in geostationary orbit (GEO) by NSAB (later SES Sirius, and now a non-autonomous part of SES S.A., owner and operator of the Astra satellites). 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.

Teracom
Teracom Group AB is a Swedish state-owned company that delivers information and communication services aimed at operators of essential functions within the Swedish civilian and military systems. Teracom was established in 1992 as a spin-off from the Swedish Televerket telecommunications agency, ahead of its corporatisation into the Swedish incumbent operator Telia. The reason behind the spin-off was to separate what became Teracom from the commercial aspect of the now-deregulated Swedish telecom business. In October 2018, Teracom sold its Danish subsidiary (Teracom A/S) to the London-based investment company Agilitas Private Equity LLP, which subsequently changed the latter's name to Cibicom A/S in January 2019. In 2019, Teracom acquired the Swedish subsidiary of the mobile wireless broadband operator Net 1, now Teracom Mobil AB. The background to Teracom's acquisition of Net1 was to secure telecommunications via mobile broadband to authorities and companies via the 450 MHz band ...

Government-owned Companies Of Sweden
State ownership, also called government ownership and public ownership, is the ownership of an industry, asset, or enterprise by the state or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership. In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a state-owned e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Television
Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver then decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service. Modern systems signals are relayed from a communications satellite on the X band (8–12 GHz) or Ku band (12–18 GHz) frequencies requiring only a small dish less than a meter in diameter. The first satellite TV systems were an obsolete type now known as television receive-only. Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellite Operators
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a universal phenomenon and a specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. An important distinction is between verbal communication, which happens through the use of a language, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astra 4A
Astra 4A is one of the Astra communications satellites owned and operated by SES at the Astra 5°E orbital slot providing digital television and radio broadcasts, data, and interactive services to Nordic countries, eastern Europe and sub-Saharan Africa in the 11.70 GHz-12.75 GHz range of the Ku band and 18.8 GHz-21.75 GHz range of the Ka band. Overview The satellite was launched in November 2007 as Sirius 4 by SES Sirius. At that time, SES owned a 75% shareholding in SES Sirius, which was increased to 90% in 2008 and to 100% in March 2010. In June 2010, the affiliate company was renamed SES Astra (then a subsidiary company of SES) and the Sirius 4 satellite was renamed Astra 4A.

Ariane 4
The Ariane 4 was a European 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. In 1982, the Ariane 4 program was approved by ESA. Drawing heavily upon the preceding Ariane 3, it was designed to provide a launcher capable of delivering heavier payloads and at a lower cost per kilogram than the earlier members of the Ariane family. The Ariane 4 was principally an evolution of the existing technologies used, as opposed to being revolutionary in its design ethos; this approach quickly gained the backing of most ESA members, who funded and participated in its development and operation. Capable of being equipped with a wide variety of strap-on boosters, the Ariane 4 gaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
