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 ...

Communications Satellites Of Israel
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, and non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellites Using The AMOS Bus
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called Transponder (satellite communications), transponders. Many satellites use a Satellite bus, standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming Satellite constellation, constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio Broadcast relay station, relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Falcon 9 Launches
Since June 2010, rockets from the Falcon 9 family have been launched times, with full mission successes, one partial failure and one total loss of the spacecraft. In addition, one rocket and its payload were destroyed on the launch pad during the fueling process before a static fire test was set to occur. Designed and operated by private manufacturer SpaceX, the Falcon 9 rocket family includes the retired versions Falcon 9 v1.0, v1.1, and v1.2 "Full Thrust" Block 1 to 4, along with the currently active Block 5 evolution. Falcon Heavy is a heavy-lift derivative of Falcon 9, combining a strengthened central core with two Falcon 9 first stages as the side boosters. The Falcon design features reusable first-stage boosters, which land either on a ground pad near the launch site or on a drone ship at sea. In December 2015, Falcon 9 became the first rocket to land propulsively after delivering a payload into orbit. This reusability has resulted in significantly reduced la ...

AMOS-3 (satellite)
AMOS-3, also known as AMOS-60, is an Israeli communications satellite operated by Spacecom Satellite Communications. History Spacecom Satellite Communications has signed an agreement in September 2005 with Israel Aerospace Industries (IAI) to buy its third satellite, AMOS-3, from the Israeli defense contractor. Satellite description The satellite is powered by twin solar panels, and is based on the Israeli AMOS Bus. It replaced AMOS-1 in geosynchronous orbit at 4° West. AMOS-3 carries fourteen Ku-band / Ka-band transponders, and is expected to have an on-orbit lifetime of 18 years. Launch It was launched atop the maiden flight of the Zenit-3SLB launch vehicle, the first launch contracted by the Land Launch organisation. The launch was originally scheduled to occur in 2007, and later March 2008, however this was delayed until 24 April 2008. The launch attempt on 24 April 2008 was scrubbed for "technical reasons". This was later determined to be a problem with the er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SPUTNIX TabletSat * ...

Amos (prophet)
In the Hebrew Bible and Christian Old Testament, Amos (; he, עָמוֹס – ''ʿĀmōs'') was one of the Twelve Minor Prophets. An older contemporary of Hosea and Isaiah, Amos was active c. 760–755 BCE during the rule of kings Jeroboam II of Israel and Uzziah of Judah. He was from the southern Kingdom of Judah but preached in the northern Kingdom of Israel. Amos wrote at a time of relative peace and prosperity but also of neglect of God's laws. He spoke against an increased disparity between the very wealthy and the very poor. His major themes of justice, God's omnipotence, and divine judgment became staples of prophecy. The Book of Amos is attributed to him. Life Before becoming a prophet, Amos was a sheep herder and a sycamore fig farmer.Coogan, Michael. ''A Brief Introduction to the Old Testament''. p. 257. Oxford: Oxford University Press, 2009. His prior professions and his claim "I am not a prophet nor a son of a prophet" () indicates that Amos was not from ...
