Ka Band
The Ka band (pronounced as either "kay-ay band" or "ka band") is a portion of the microwave part of the electromagnetic spectrum defined as frequencies in the range 26.5–40 gigahertz (GHz), i.e. wavelengths from slightly over one centimeter down to 7.5 millimeters. The band is called Ka, short for "K-above" because it is the upper part of the original NATO K band, which was split into three bands because of the presence of the atmospheric water vapor resonance peak at 22.24 GHz (1.35 cm), which made the center unusable for long range transmission. The 30/20 GHz band is used in communications satellite uplinks in either the 27.5 GHz and 31 GHz bands, and high-resolution, close-range targeting radars aboard military airplanes. Some frequencies in this radio band are used for vehicle speed detection by law enforcement. The Kepler Mission used this frequency range to downlink the scientific data collected by the space telescope. The designation " ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabia (including the Arabian Peninsula and Bahrain), Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sinai Region) and all of Turkey (not just the part barring East Thrace). ...

Astra 2E
Astra 2E is one of the Astra communications satellites owned and operated by SES S.A., launched to the Astra 28.2°E orbital position on 30 September 2013 after a 10-week delay caused by launcher problems. The satellite provides free-to-air and encrypted direct-to-home (DTH) digital television and satellite broadband services for Europe and the Middle East. After launch, Astra 2E underwent in-orbit testing at 43.5° East and began commercial operations at 28.2° East in February 2014. At that time, channels broadcast via Astra 1N (temporarily located at 28.2° East pending Astra 1E's launch) were transferred to Astra 2E and Astra 1N relocated to its design position at 19.2° East. Astra 2E is the second of three "second generation" satellites for the 28.2° East position to replace the first generation Astra 2A, Astra 2B, Astra 2C and Astra 2D craft originally positioned there between 1998 and 2001.

Astra 2D
Astra 2D is one of the Astra communications satellites owned and operated by Société Européenne des Satellites (SES), and located at 28.2° East in the geostationary orbit until June 2015. It is a Hughes Space and Communications HS-376HP satellite bus, and was launched from the Centre Spatial Guyanais in December 2000 to join Astra 2A and Astra 2B at 28.2° East, where it remained for its active life. As of February 2013, Astra 2D has carried no regularly active transponders. In service While active, most of Astra 2D's transponders were used to provide television channels available on the Sky Digital satellite service to both Ireland and the United Kingdom, as well as the non-subscription service, freesat. Provision of rights-sensitive broadcasts free-to-air was made possible by the satellite's beam that was tightly focused on Ireland and the United Kingdom. However, surrounding countries had the ability to pick up the signal (dependent on suitably sized satellite di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astra 2C
Astra 2C is one of the Astra communications satellites owned and operated by Société Eurpéenne des Satellites. Designed to join Astra 2A and Astra 2B at the Astra 28.2°E orbital position providing digital television and radio broadcast services to the United Kingdom and Ireland, the satellite was first used after launch in 2001 at 19.2° East for pan-European coverage. The satellite provides one broadcast beam with horizontal and vertical polarisation, across a single footprint covering the areas of Central and Eastern Europe, Scandinavia, the Iberian Peninsula and Canary Islands. TV signals can be received with a 50 cm dish across the majority of the British Isles with a 60 cm dish required in the extreme north and west. Astra 2C can also provide backup capacity, substituting for one or more transponders across the 10.70-12.20 GHz broadcast range used by Astra satellites in the Astra 19.2°E and Astra 28.2°E orbital positions.

Astra 2B
Astra 2B is one of the Astra communications satellites owned and operated by Société Européenne des Satellites. Launched in September 2000 to join Astra 2A at the Astra 28.2°E orbital position providing digital television and radio broadcast services to the United Kingdom and Ireland, the satellite has also served at the Astra 19.2°E and the Astra 31.5°E positions. History The satellite provides two broadcast beams, each with horizontal and vertical polarisation, across two footprints - 2B North (covering Central Europe and Scandinavia) and 2B South (covering Central Europe and the Iberian Peninsula and Canary Islands). While at 28.2° East, television signals could be received with a 43 cm dish across the majority of the British Isles with a 60 cm dish required in the extreme north and west, although the official footprint maps now show a 60 cm dish as required across all of Western Europe. At 28.2° East, 17 transponders on Astra 2B were used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astra 2A
Astra 2A is one of the Astra communications satellites owned by Société Européenne des Satellites. Launched in 1998 into the 28.2° East orbital position, half its expected end-of-life capacity of 28 transponders were pre-booked by BSkyB, who utilised it to launch their new Sky Digital service. In March 2015, the satellite has been deactivated and relocated to 113.5° East. History The satellite suffered pre-launch technical issues with its apogee motors and was moved to a launch by the Proton-K / DM-03 rather than the Ariane 5, as the Proton can inject directly in geostationary orbit (GEO). When positioned at 28.2 East, it joined DFS Kopernikus-1, which served mainly Eastern Europe. The satellite was the first of Astra's craft to never carry analogue television services (with the exception of a solitary test card in 1999 ), and as of 2006, carried standard definition digital television, digital radio, and high-definition digital television, as well as Sky Interactive ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications ...

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 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. At the time of the launch of the first Astra satellite, Astra 1A in 1988, the satellite's operator was known as Société Européenne des Satellites. In 2001 SES Astra, a newly formed subsidiary of SES, operated the Astra satellites and in September 2011, SES Astra was consolidated back into the parent company, which by this time also operated other satellite families such as AMC, and NSS. Astra satellites broadcast 2600 digital television channels (675 in high definition) via five main satellite orbital positions to households across Asia, Australia, Africa, Americas, Europe, New Zea ...
