EchoStar 23
EchoStar Corporation is an American company, a worldwide provider of satellite communication and Internet services through its Hughes Network Systems and EchoStar Satellite Services business segments. EchoStar is based out of unincorporated Arapahoe County, Colorado. Prior to 2008, it operated the DISH Network service brand, which was spun off as DISH on January 1, 2008. History EchoStar was originally formed in 1980 by its chairman Charles Ergen as a distributor of C band TV systems. In 1987, it applied for a direct broadcast satellite (DBS) license with the Federal Communications Commission and was granted access to orbital slot 119° west longitude in 1992. On December 28, 1995, the firm successfully launched its first satellite, EchoStar I. On March 4, 1996, it established the DISH Network brand name to market its home satellite TV system. On January 2, 2008, the DISH Network business was demerged from the technology and infrastructure side of the business. A split i ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange ( listed company), which facilitates the trade of shares, or not ( unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), ...

Marketing
Marketing is the process of exploring, creating, and delivering value to meet the needs of a target market in terms of goods and services; potentially including selection of a target audience; selection of certain attributes or themes to emphasize in advertising; operation of advertising campaigns; attendance at trade shows and public events; design of products and packaging attractive to buyers; defining the terms of sale, such as price, discounts, warranty, and return policy; product placement in media or with people believed to influence the buying habits of others; agreements with retailers, wholesale distributors, or resellers; and attempts to create awareness of, loyalty to, and positive feelings about a brand. Marketing is typically done by the seller, typically a retailer or manufacturer. Sometimes tasks are contracted to a dedicated marketing firm or advertising agency. More rarely, a trade association or government agency (such as the Agricultural Marketing Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ariane 5
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development. The system was designed as an expendable launch system by the '' Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it is classified as part of the Ariane rocket family. ArianeGroup is the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally int ...

EchoStar XVII
EchoStar XVII or EchoStar 17, also known as Jupiter 1, is an American geostationary high throughput communications satellite which is operated by Hughes Network Systems, a subsidiary of EchoStar. It is positioned in geostationary orbit at a longitude of 107.1° West, from where it is used for satellite internet access over HughesNet. EchoStar XVII was built by Space Systems/Loral, and is based on the LS-1300 satellite bus. It measures by by , with solar arrays which were deployed after launch, and generates a minimum of 16.1 kilowatts of power. The spacecraft had a mass at liftoff of , and is expected to operate for fifteen years. It carries sixty (NATO K band) transponders which is used to cover North America. EchoStar XVII was launched by Arianespace, using an Ariane 5ECA carrier rocket flying from ELA-3 at Kourou. The spacecraft was launched at 21:36 UTC on 5 July 2012. The MSG-3 weather satellite was launched aboard the same rocket, mounted below EchoStar XVII, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galaxy 23
Galaxy 23 is the name given to the C-band service of the Galaxy 23/EchoStar 9 communications satellite jointly owned by Intelsat and EchoStar located at 121° W longitude, serving the North American market. It was built by Space Systems/Loral, as part of its FS-1300 line. Galaxy 23 was formerly known as Intelsat Americas 13. The "Galaxy 23" portion of the service provides transponders in the C band. The "EchoStar 9" portion broadcasts Ku band, and Ka band transponders. While the satellite itself is jointly owned through a partnership between Intelsat and Echostar, the Ku band payload is owned and operated by Echostar for international television programming and local television channels. That service is intended for Dish Network customers using a SuperDish system. The C-band payload is owned and operated by Intelsat. The Ka band payload is owned and operated by Echostar for as-yet-undisclosed purposes. Current clients for Galaxy 23/EchoStar 9 include Dish Network, D ...

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 "Ka ...

Ku Band
The Ku band () is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally german: Kurz-unten), because it is the lower part of the original NATO K band, which was split into three bands (Ku, K, and Ka) 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. In radar applications, it ranges from 12 to 18 GHz according to the formal definition of radar frequency band nomenclature in IEEE Standard 521–2002. Ku band is primarily used for satellite communications, most notably the downlink used by direct broadcast satellites to broadcast satellite television, and for specific applications such as NASA's Tracking Data Relay Satellite used for International Space Station (ISS) communications and SpaceX Starlink satellites. Ku band satellites are also u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
