Nordic Satellite AB
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 Gui ...

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, 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. Satellites Sirius 4 A fourth satellite, Sirius 4, was ordered in 2005 and launched at 22:39:47 UTC on 17 November 2007. It carries 52 active Ku-band transponders and two active Ka-band transponders. Sirius 4 was built by Lockheed Martin Space Systems based upon the A2100AX design. Among the services carried are Viasat and Viasat Ukraine which has used the Sirius satellites for their digital platform since its laun ...

Government-owned Companies Of Sweden
State ownership, also called public ownership or government ownership, is the ownership of an industry, asset, property, or enterprise by the national government of a country or 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. ...

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.ITU Radio Regulations, Section IV. Radio Stations and Systems – Article 1.39, definition: ''Broadcasting-satellite service'' 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 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. Different receivers are required for the two types. Some transmissions and channels are unencrypted and therefore free-to-air, while many other channels are transmitted with enc ...

Communications Satellite Operators
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether Intention, unintentional or failed transmissions are included and whether communication not only transmits semantics, meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a code, coding system to express information in the form of a message. The message is sent through a Communication channel, channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies. A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between Verbal communication, verbal and non-verbal communication. Verba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SES Astra
SES Astra SA was a corporate subsidiary of SES, based in Betzdorf, in eastern Luxembourg, that maintained and operated the Astra series of geostationary communication satellites between 2001 and 2011. Formed in 1985 as Société Européenne des Satellites ( SES), it was Europe's first private satellite operator. In November 2001, upon the purchase of GE Americom from General Electric (renamed to SES Americom), SES Global was formed as the parent company to SES Americom and SES Astra. SES Astra was formed at that time as a subsidiary company to contain all of SES's existing European based satellite operations. In September 2011, SES Astra and sister subsidiary SES World Skies (formed from SES Americom and SES New Skies) were merged back into SES to streamline operations under a single management system. Subsidiaries of SES Astra, such as HD Plus and ASTRA Broadband Services became direct subsidiaries of SES. The brand name, ''Astra'', representing the satellite family and ...

Ariane 4
The Ariane 4 was a European expendable rocket, expendable launch vehicle in the Ariane (rocket family), Ariane family, developed by the (CNES), the Government of France, French space agency, for the European Space Agency (ESA). The manufacturing of the launch vehicle was led by Aérospatiale and it was 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.

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 Net 1 was to secure telecommunications via mobile broadband to authorities and companies via the 450 MHz ...

Astra (satellites)
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, 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.
