AMOS-1 (satellite)
AMOS-1, then INTELSAT 24, is a commercial communications satellite which was operated by Spacecom as AMOS-1, for ''Affordable Modular Optimized Satellite'' and formed part of the AMOS series of satellites. It was the first Israeli civilian communications satellite, and was initially positioned at 4° West longitude in geostationary orbit. Then in September 2011, it was moved to 31° East. Satellite description Its development was based on experience from Ofeq reconnaissance satellites in association with DASA and Alcatel Espace. It was used for home television services ( DTH/ DBS by "Yes" company in Israel and by HBO and others in Europe). Spacecom succeeded quickly to fill all transmission abilities of AMOS-1 and accumulated additional requests. Therefore, Spacecom decided to build AMOS-2, which replaced AMOS-1 on orbit at 4° West. AMOS-1 carries nine Ku-band transponders. Weighing 970 kg at launch, AMOS-1 incorporated a 400 newtons liquid apogee motor and fourteen ...

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] |

DASA
''Dasa'' ( sa, दास, Dāsa) is a Sanskrit word found in ancient Indian texts such as the ''Rigveda'' and ''Arthasastra''. It usually means "enemy" or "servant" but ''dasa'', or ''das'', also means a "servant of God", "devotee," "votary" or "one who has surrendered to God". Dasa may be a suffix of a given name to indicate a "servant" of a revered person or a particular deity. ''Dasa'', in some contexts, is also related to ''dasyu'' and ''asura'', which have been translated by some scholars as "demon", "harmful supernatural forces", "slave", "servant" or "barbarian", depending on the context in which the word is used.Wash Edward Hale (1999), Ásura- in Early Vedic Religion, Motilal Barnarsidass, , pages 159-169 Etymology ''Dāsa'' first appears in Vedic texts from the second millennium BCE. There is no consensus on its origins. Karl Heinrich Tzschucke in 1806, in his translations of the Roman geographer Pomponius Mela, noted etymological and phonological parallels between '' ...

Reconnaissance Satellite
A reconnaissance satellite or intelligence satellite (commonly, although unofficially, referred to as a spy satellite) is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type (i.e., Corona and Zenit) took photographs, then ejected canisters of photographic film which would descend back down into Earth's atmosphere. Corona capsules were retrieved in mid-air as they floated down on parachutes. Later, spacecraft had digital imaging systems and downloaded the images via encrypted radio links. In the United States, most information available about reconnaissance satellites is on programs that existed up to 1972, as this information has been declassified due to its age. Some information about programs before that time is still classified information, and a small amount of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassified o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ofeq
Ofeq, also spelled Offek or Ofek ( he, אופק, ''lit.'' Horizon) is the designation of a series of Israeli reconnaissance satellites first launched in 1988. Most Ofeq satellites have been carried on top of Shavit 2 launch vehicles from Palmachim Airbase in Israel, on the Mediterranean coast. The low Earth orbit satellites complete one Earth orbit every 90 minutes. The satellite launches made Israel the eighth nation to gain an indigenous launch capability. Both the satellites and the launchers were designed and manufactured by Israel Aerospace Industries (IAI) with Elbit Systems' El-Op division supplying the optical payload. Description While exact technical details and capabilities are classified, it is assumed that the Ofeq satellites have an effective operational lifespan of 1–3 years and ultraviolet and visible imaging sensors (except Ofeq-8 and -10 which utilize synthetic-aperture radar (SAR) for all-weather and nighttime reconnaissance). Some reports place the imagi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geostationary Orbit
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 sat ...

Longitude
Longitude (, ) is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of time allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 sate ...
