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 22,236 miles (35,785 km) 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.

In May 2012, DISH launched DISHWorld, a subscription-based over-the-top streaming IPTV service, as an app on Roku devices, offering access to over 50 international television channels via broadband streaming. In 2014, DISH Network began to reach carriage deals with broadcasters for
940-518: A medium Earth orbit satellite is about 16,000 kilometres (10,000 mi) above Earth. In various patterns, these satellites make the trip around Earth in anywhere from 2 to 8 hours. To an observer on Earth, a satellite in a gestationary orbit appears motionless, in a fixed position in the sky. This is because it revolves around the Earth at Earth's own angular velocity (one revolution per sidereal day , in an equatorial orbit ). A geostationary orbit
1034-591: A more precise match for the capabilities of geosynchronous comsats. Two satellite types are used for North American television and radio: Direct broadcast satellite (DBS), and Fixed Service Satellite (FSS). The definitions of FSS and DBS satellites outside of North America, especially in Europe, are a bit more ambiguous. Most satellites used for direct-to-home television in Europe have the same high power output as DBS-class satellites in North America, but use

The company has engaged in disaster relief efforts, including after Hurricanes Katrina , Harvey , Irma , and Maria . Both
1504-621: A period (time to revolve around the Earth) of about 90 minutes. Because of their low altitude, these satellites are only visible from within a radius of roughly 1,000 kilometres (620 mi) from the sub-satellite point. In addition, satellites in low Earth orbit change their position relative to the ground position quickly. So even for local applications, many satellites are needed if the mission requires uninterrupted connectivity. Low-Earth-orbiting satellites are less expensive to launch into orbit than geostationary satellites and, due to proximity to

These set-top boxes (STBs) allow for HD on the primary TV and SD on the secondary TV (TV2) without
2350-523: A tactical necessity, and the ultimate goal of this project was the creation of the longest communications circuit in human history, with the Moon, Earth's natural satellite, acting as a passive relay. After achieving the first transoceanic communication between Washington, D.C. , and Hawaii on 23 January 1956, this system was publicly inaugurated and put into formal production in January 1960. The first satellite purpose-built to actively relay communications
2444-553: Is also possible to offer discontinuous coverage using a low-Earth-orbit satellite capable of storing data received while passing over one part of Earth and transmitting it later while passing over another part. This will be the case with the CASCADE system of Canada's CASSIOPE communications satellite. Another system using this store and forward method is Orbcomm . A medium Earth orbit is a satellite in orbit somewhere between 2,000 and 35,786 kilometres (1,243 and 22,236 mi) above

To facilitate frequency planning, the world is divided into three regions: Within these regions, frequency bands are allocated to various satellite services, although a given service may be allocated different frequency bands in different regions. Some of the services provided by satellites are: The first and historically most important application for communication satellites
2632-492: Is highly inclined, guaranteeing good elevation over selected positions during the northern portion of the orbit. (Elevation is the extent of the satellite's position above the horizon. Thus, a satellite at the horizon has zero elevation and a satellite directly overhead has elevation of 90 degrees.) The Molniya orbit is designed so that the satellite spends the great majority of its time over the far northern latitudes, during which its ground footprint moves only slightly. Its period
2726-558: Is known as a satellite constellation . Two such constellations, intended to provide satellite phone and low-speed data services, primarily to remote areas, are the Iridium and Globalstar systems. The Iridium system has 66 satellites, which orbital inclination of 86.4° and inter-satellite links provide service availability over the entire surface of Earth. Starlink is a satellite internet constellation operated by SpaceX , that aims for global satellite Internet access coverage. It
2820-576: Is one half day, so that the satellite is available for operation over the targeted region for six to nine hours every second revolution. In this way a constellation of three Molniya satellites (plus in-orbit spares) can provide uninterrupted coverage. The first satellite of the Molniya series was launched on 23 April 1965 and was used for experimental transmission of TV signals from a Moscow uplink station to downlink stations located in Siberia and
2914-410: Is that a MEO satellite's distance gives it a longer time delay and weaker signal than a LEO satellite, although these limitations are not as severe as those of a GEO satellite. Like LEOs, these satellites do not maintain a stationary distance from the Earth. This is in contrast to the geostationary orbit, where satellites are always 35,786 kilometres (22,236 mi) from Earth. Typically the orbit of

This will cause problems for extreme northerly latitudes, affecting connectivity and causing multipath interference (caused by signals reflecting off the ground and into the ground antenna). Thus, for areas close to the North (and South) Pole, a geostationary satellite may appear below the horizon. Therefore, Molniya orbit satellites have been launched, mainly in Russia, to alleviate this problem. Molniya orbits can be an appealing alternative in such cases. The Molniya orbit

The combined company will have a total of approximately 20 million television subscribers. DirecTV stated that it had no plans for any changes to the DISH or SlingTV services following the purchase. The sale comes amid declines in both services' customer bases amid cord-cutting and other factors. EchoStar CEO Hamid Akhavan stated that
6768-487: The risk of signal interference. In October 1945, Arthur C. Clarke published an article titled "Extraterrestrial Relays" in the British magazine Wireless World . The article described the fundamentals behind the deployment of artificial satellites in geostationary orbits to relay radio signals. Because of this, Arthur C. Clarke is often quoted as being the inventor of the concept of the communications satellite, and
6862-1047: The same linear polarization as FSS-class satellites. Examples of these are the Astra , Eutelsat , and Hotbird spacecraft in orbit over the European continent. Because of this, the terms FSS and DBS are more so used throughout the North American continent, and are uncommon in Europe. Fixed Service Satellites use the C band , and the lower portions of the K u band . They are normally used for broadcast feeds to and from television networks and local affiliate stations (such as program feeds for network and syndicated programming, live shots , and backhauls ), as well as being used for distance learning by schools and universities, business television (BTV), Videoconferencing , and general commercial telecommunications. FSS satellites are also used to distribute national cable channels to cable television headends. Free-to-air satellite TV channels are also usually distributed on FSS satellites in
6956-538: The services. This was only temporary, as they got brought back later. They had previously been pulled from YouTube TV in 2021, and were pulled from Spectrum for ten days in early-September 2023. The last remaining regional sports network, NESN , was removed from DISH on December 20, 2021. In February 2023, Dish Network suffered a major ransomware attack which resulted in internal outages, loss of service at subsidiary companies such as Boost Mobile , and data theft. The company had to retain outside experts to resolve
7050-408: The signal coming from the source, toward the direction of the receiver. With passive satellites, the reflected signal is not amplified at the satellite, and only a small amount of the transmitted energy actually reaches the receiver. Since the satellite is so far above Earth, the radio signal is attenuated due to free-space path loss , so the signal received on Earth is very weak. Active satellites, on
7144-402: The sky for transmission of communication signals. However, due to their closer distance to the Earth, LEO or MEO satellites can communicate to ground with reduced latency and at lower power than would be required from a geosynchronous orbit. A low Earth orbit (LEO) typically is a circular orbit about 160 to 2,000 kilometres (99 to 1,243 mi) above the Earth's surface and, correspondingly,
7238-477: The spin-off, the company pursued further acquisitions and business initiatives, including acquiring video rental chain Blockbuster in an attempt to compete with Netflix , releasing a new set-top digital video recorder (DVR) with the controversial ability to automatically skip commercials in recordings. In 2015, the company launched over-the-top IPTV services via the new subsidiary Sling TV . In 2020,
7332-572: The technology side including the satellites, Sling Media, and the set-top box development arm. Dish Network completed its distribution to EchoStar of its digital set-top box business, certain infrastructure, and other assets and related liabilities, including certain of their satellites, uplink and satellite transmission assets, and real estate. Following the spin-off, EchoStar and Dish Network operated as separate publicly traded companies, until they were reunited in 2023. On February 14, 2011, EchoStar announced that it would acquire Hughes Communications in
7426-590: The term 'Clarke Belt' is employed as a description of the orbit. The first artificial Earth satellite was Sputnik 1 , which was put into orbit by the Soviet Union on 4 October 1957. It was developed by Mikhail Tikhonravov and Sergey Korolev , building on work by Konstantin Tsiolkovsky . Sputnik 1 was equipped with an on-board radio transmitter that worked on two frequencies of 20.005 and 40.002 MHz, or 7 and 15 meters wavelength. The satellite
7520-515: Was Project SCORE , led by Advanced Research Projects Agency (ARPA) and launched on 18 December 1958, which used a tape recorder to carry a stored voice message, as well as to receive, store, and retransmit messages. It was used to send a Christmas greeting to the world from U.S. President Dwight D. Eisenhower . The satellite also executed several realtime transmissions before the non-rechargeable batteries failed on 30 December 1958 after eight hours of actual operation. The direct successor to SCORE
7614-429: Was another ARPA-led project called Courier. Courier 1B was launched on 4 October 1960 to explore whether it would be possible to establish a global military communications network by using "delayed repeater" satellites, which receive and store information until commanded to rebroadcast them. After 17 days, a command system failure ended communications from the satellite. NASA 's satellite applications program launched
7708-440: Was completed December 31, 2023, was part of an effort to bolster the company's wireless business, with Ergen stating that it would allow them to offer "an enhanced consumer connectivity business". As Ergen already held 90% of the voting stock in both companies, the FCC considered the "acquisition" to be a reorganization of assets with no change in effective control. In July 2024, amid declines in subscribers, Boost Mobile underwent
7802-545: Was completed on July 1, 2020. With this purchase it officially launched its wireless business, DISH Wireless, offering prepaid service through the Boost brand as an MVNO on the T-Mobile network. DISH stated intentions to offer branded postpaid service in the future with the build-out of their own network. DISH purchased Ting Mobile from Tucows on August 1, 2020, Republic Wireless on March 8, 2021, and Gen Mobile on September 1, 2021. On July 19, 2021, DISH announced
7896-484: Was completed on September 10, 2019. On August 8, 2023, The Hollywood Reporter reported that Ergen was proposing a remerger between Dish and EchoStar. Later that day, the acquisition was formally announced by both companies. On January 2, 2024, it was announced that the transaction had been completed on December 31, 2023. In May 2024, EchoStar announced that it has been awarded a U.S. Navy wireless and telecommunications contract to provide 5G smart devices and services for
7990-448: Was fined $ 150,000 by the FCC for failing to de-orbit its EchoStar VII satellite according to the terms of its license; this was the first fine ever issued to a company over the matter of " space debris ". Dish Network has always refused to carry some of the higher-priced regional sports networks , most notably AT&T SportsNet Southwest , YES Network , and Spectrum SportsNet , which have never been available on Dish. The contract of
8084-469: Was founded in 2008 after the original EchoStar spun off its non-consumer assets while the original company was renamed to Dish Network Corporation. In an industry reverse, EchoStar proposed to buy Dish in 2023 with the acquisition being completed by the end of that year, as a result, Dish was absorbed into EchoStar as a whole. EchoStar made its debut on the Fortune 500 list in 2024, ranking #242. EchoStar
8178-428: Was in intercontinental long distance telephony . The fixed Public Switched Telephone Network relays telephone calls from land line telephones to an Earth station , where they are then transmitted to a geostationary satellite. The downlink follows an analogous path. Improvements in submarine communications cables through the use of fiber-optics caused some decline in the use of satellites for fixed telephony in
8272-492: Was launched, the United States was the only launch source outside of the Soviet Union , who did not participate in the Intelsat agreements. The Soviet Union launched its first communications satellite on 23 April 1965 as part of the Molniya program. This program was also unique at the time for its use of what then became known as the Molniya orbit , which describes a highly elliptical orbit , with two high apogees daily over
8366-493: Was needed to track it. Its successor, Syncom 3 , launched on 19 July 1964, was the first geostationary communications satellite. Syncom 3 obtained a geosynchronous orbit, without a north–south motion, making it appear from the ground as a stationary object in the sky. A direct extension of the passive experiments of Project West Ford was the Lincoln Experimental Satellite program, also conducted by
8460-500: Was not placed in orbit to send data from one point on Earth to another, but the radio transmitter was meant to study the properties of radio wave distribution throughout the ionosphere. The launch of Sputnik 1 was a major step in the exploration of space and rocket development, and marks the beginning of the Space Age . There are two major classes of communications satellites, passive and active . Passive satellites only reflect
8554-447: Was originally established as EchoStar Communications , and first launched its satellite television services under the DISH Network brand in 1996, utilizing its EchoStar I satellite. In 2007, EchoStar spun off its television business as DISH Network Corporation, with the satellite technology and infrastructural assets remaining under EchoStar. Both companies would remain under the control of EchoStar's co-founder Charlie Ergen . After
8648-409: 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
8742-644: Was subject to instruction by the US Government on matters of national policy. Over the next two years, international negotiations led to the Intelsat Agreements, which in turn led to the launch of Intelsat 1, also known as Early Bird, on 6 April 1965, and which was the first commercial communications satellite to be placed in geosynchronous orbit. Subsequent Intelsat launches in the 1960s provided multi-destination service and video, audio, and data service to ships at sea (Intelsat 2 in 1966–67), and
8836-591: Was the first active, direct relay communications commercial satellite and marked the first transatlantic transmission of television signals. Belonging to AT&T as part of a multi-national agreement between AT&T, Bell Telephone Laboratories , NASA, the British General Post Office , and the French National PTT (Post Office) to develop satellite communications, it was launched by NASA from Cape Canaveral on 10 July 1962, in
