DFS Kopernikus
DFS Kopernikus (meaning ''Deutscher Fernmeldesatellit Kopernikus'') was the name of three geostationary satellites of Deutsche Bundespost and later Deutsche Telekom AG. They are no longer in use. DFS Kopernicus-3 When DFS Kopernikus-3 was nearing the end of its life, SES sealed an agreement with Deutsche Telekom to use the 23.5° East position and frequencies, and in August 2001, Astra 1D was moved there."New position for ASTRA 1D"

Geostationary Satellite
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sate ...

Deutsche Bundespost
The Deutsche Bundespost (German federal post office) was a German state-run postal service and telecommunications business founded in 1947. It was initially the second largest federal employer during its time. After staff reductions in the 1980s, the staff was reduced to roughly 543,200 employees in 1985. The corporation was dissolved in 1995 under two rounds of postal reforms that took place in the German Post Office in 1989 and 1995, respectively. Following the reforms, the former Deutsche Bundespost was broken into three publicly traded corporations: Deutsche Post AG (German Post), Deutsche Telekom (German Telecom), and Deutsche Postbank AG (German Post Bank). History Created in 1947 in the Trizone as a successor to the ''Reichspost'' (German imperial post office), until 1950 the enterprise was called ''Deutsche Post'' (German post office). Until 1989, the ''Deutsche Bundespost'' was a state-owned operation. Organization The ''Bundespost'' was developed according to a ...

Astra 1D
Astra 1D is a geostationary communications satellite launched in 1994 by the Société Européenne des Satellites (SES). , the craft remains in service for occasional use. Astra 1D was the fourth, and under original plans, last Astra communications satellite from SES. It was launched to SES' original solitary operational position at 19.2° East, and was intended as an in-orbit spare for Astra's Astra 1A, 1B and 1C and to carry digital TV transmissions. However, development of digital reception equipment in Europe was not sufficiently advanced for Astra 1D to be SES' first digital satellite (the later Astra 1E fulfilled that role) and demand for additional capacity for both British and German television channels led to 12 of the satellite's transponders being leased to broadcast analogue TV channels before the satellite had been launched. History After launch to 19.2° East, Astra 1D served two periods as a spare at the Astra 28.2°E position colocated with Astra 2A, for s ...

Astra 3A
Astra 3A is one of the Astra communications satellites owned and operated by Société Européenne des Satellites, launched in March 2002 to the Astra 23.5°E orbital position to provide digital television and radio for direct to home (DTH) and cable, multimedia and interactive services, corporate networks, and occasional and other business services to Europe. The satellite provides two broadcast beams, of horizontal and vertical polarisation, across two footprints that covered essentially the same areas of Europe – principally the countries of central Europe. History Astra 3A was launched to provide follow-on capacity to replace the DFS Kopernikus-3 satellite and deliver additional capacity for the Benelux countries and central Europe, to create SES-Astra's third major European satellite hotspot after Astra 19.2°E and Astra 28.2°E with access to channels at both positions using a single dish fitted with a monoblock Duo LNB. In that role, television signals could be re ...

DFS Kopernikus-3
DFS Kopernikus-3 (or Deutscher Fernmelde Satellit-3 and Hellas Sat 1) was a communications satellite operated by Deutsche Telekom. Satellite description The DFS Kopernikus series of satellites debuted in 1989 with the third being launched in 1992. Ordered in 1983 and produced by the GESAT consortium of MBB (flight segment prime contractor), Siemens (overall prime contractor), ANT Nachrichtentechnik (payload), Standard Elektrik Lorenz (digital switching equipment), and Dornier Systems (ground control system), DFS spacecraft are smaller than TV-Sat: on-station mass is 850 kg with a 15.4 m solar array span providing up to 1.5 kW of electrical power. The satellite also used a propulsion system S400. The communications payload includes ten 14/11-12 GHz transponders with five spares and one experimental 30/20 GHz transponder with one spare. At the end of 1994, DFS 1-3 were stationed at 33.5° East, 28.5° East, and 23.5° East, respectively. Like TV-Sat, the DFS K ...

Oberpfaffenhofen
Oberpfaffenhofen is a village that is part of the municipality of Weßling in the district of Starnberg, Bavaria, Germany. It is located about from the city center of Munich. Village The village is home to the Oberpfaffenhofen Airport and a major site of the German Aerospace Center (''Deutsches Zentrum für Luft- und Raumfahrt'', DLR). Oberpfaffenhofen became known to a wide audience when, in 1983, the first West-German astronaut, the physicist Ulf Merbold, flew to space onboard a Space Shuttle in a Spacelab mission. These missions were partly supervised by the German Space Operations Center located at Oberpfaffenhofen. The research center in Oberpfaffenhofen houses the DLR, including the Columbus Control Center which DLR operates for the European Space Agency and Airbus Defence and Space, and also some Fraunhofer Institutes and other scientific institutes.

Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an ind ...

TV-SAT 1
TV-SAT 1 or TVSAT-1 was a West German communications satellite, which was to have been operated by Deutsche Bundespost. It was intended to provide television broadcast services to Europe, but it failed before entering service. It was built by Aérospatiale, was based on the Spacebus 300 satellite bus, and carried five Ku-band transponders. At launch it had a mass of , and an expected operational lifespan of eight years. Launch TV-SAT 1 was launched by Arianespace using an Ariane 2 rocket flying from ELA-2 at Centre Spatial Guyanais, Kourou, French Guiana. The launch took place at 02:19:00 UTC on 21 November 1987. It was the first Spacebus 300 satellite to be launched. Immediately after launch, one of its solar panels failed to deploy, so that the main uplink antenna, behind the solar panel, could not deploy either. This failure was caused by the presence of two hold-down bolts, which should have been removed before launch. Mission Despite the failure, TV-SAT 1 was placed in ...
