Briz (rocket Stage)
The Briz-K, Briz-KM and Briz-M ( meaning ''Breeze-K, KM and M'') are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M and Angara A5. The upper stages were also used on Rokot, one of Russia's smaller launchers, before its retirement in 2019. Characteristics Briz-K and Briz-KM Briz-K, GRAU index 14S12, is a single-piece structure with a conical tank compartment and the engine located in a recess in the fuel tank. Briz-KM ( GRAU index 14S45) is an improved version of Briz-K. The Briz-K and Briz-KM were used as a third stage of the Rokot launch vehicles. Briz-M Briz-M, GRAU index 14S43, is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit. Briz-M is a twin upper stage consisting of a core module (using Briz-KM as the baseline) and a jettisonable add-on toroidal tank surrounding the core. It is powered by a pump-fed gimba ...

Paris Air Show
The Paris Air Show (, ''Salon du Bourget'') is a trade fair and air show held in odd years at Paris–Le Bourget Airport in France. Organized by the French aerospace industry's primary representative body, the ''Groupement des industries françaises aéronautiques et spatiales'' (GIFAS), it is the largest air show and aerospace-industry exhibition event in the world, measured by number of exhibitors and size of exhibit space, followed by UK's Farnborough Air Show, Dubai Air Show, and Singapore Airshow. First held in 1909, the Paris Air Show was held every odd year from 1949 to 2019, when the 53rd Air Show attracted 2,453 exhibitors from 49 countries and occupied more than 125,000 square meters. Organizers canceled the 2021 show due to the COVID pandemic. It resumed in 2023. It is a large trade fair, demonstrating military and civilian aircraft, and is attended by many military forces and the major aircraft manufacturers, often announcing major aircraft sales. It starts with four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angara (rocket Family)
The Angara (; ) or Angar ( мүрэн) is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is long, and has a drainage basin of . It was formerly known as the Lower or Nizhnyaya Angara (distinguishing it from the Upper Angara). Below its junction with the Ilim, it was formerly known as the Upper Tunguska (, ''Verhnyaya Tunguska'', distinguishing it from the Lower Tunguska) and, with the names reversed, as the Lower Tunguska. Course Leaving Lake Baikal near the settlement of Listvyanka, the Angara flows north past the Irkutsk Oblast cities of Irkutsk, Angarsk, Bratsk, and Ust-Ilimsk. It then crosses the Angara Range and turns west, entering Krasnoyarsk Krai, and joining the Yenisey near Strelka, south-east of Lesosibirsk.

Intelsat
Intelsat S.A. (formerly Intel-Sat, Intelsat) is a Luxembourgish-American multinational satellite services provider with corporate headquarters in Luxembourg and administrative headquarters in Tysons, Virginia, United States. Originally formed as International Telecommunications Satellite Organization (''ITSO'', or Intelsat), from 1964 to 2001, it was an intergovernmental consortium owning and managing a constellation of communications satellites providing international telecommunications and broadcast services.

GLONASS
GLONASS (, ; ) is a Russian satellite navigation system operating as part of a radionavigation-satellite service. It provides an alternative to Global Positioning System (GPS) and is the second navigational system in operation with global coverage and of comparable precision. Satellite navigation devices supporting both GPS and GLONASS have more satellites available, meaning positions can be fixed more quickly and accurately, especially in built-up areas where buildings may obscure the view to some satellites. Owing to its higher orbital inclination, GLONASS supplementation of GPS systems also improves positioning in high latitudes (near the poles). Development of GLONASS began in the Soviet Union in 1976. Beginning on 12 October 1982, numerous rocket launches added satellites to the system until the completion of the Satellite constellation, constellation in 1995. In 2001, after a decline in capacity during the late 1990s, the restoration of the system was made a government p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SES Americom
SES Americom was a major commercial satellite operator of North American geosynchronous satellites based in the United States. The company started as RCA Americom in 1975 before being bought by General Electric in 1986 and then later acquired by SES in 2001. In September 2009, SES Americom and SES New Skies merged into SES World Skies. History RCA American Communications (RCA Americom) was founded in 1975 as an operator of RCA Astro Electronics-built satellites. The company's first satellite; Satcom 1, was launched on 12 December 1975. Satcom 1 was one of the earliest geostationary satellites. Satcom 1 was instrumental in helping early cable TV channels (such as Superstation TBS and CBN) to become initially successful, because these channels distributed their programming to all of the local cable TV headends using the satellite. Additionally, it was the first satellite used by broadcast TV networks in the United States, like American Broadcasting Company (ABC), NBC, a ...

Baikonur Cosmodrome Site 200
Site 200 at the Baikonur Cosmodrome is a launch site used by Proton rockets. It consists of two launch pads, areas 39 and 40. Area 39 is currently (as of 2021) used for Proton-M launches, including commercial flights conducted by International Launch Services. Area 40 is currently (as of 2021) inactive, as it was slated to be rebuilt as a launch site for the Angara rocket. Although the project was relocated to Site 250, Area 40 was not put back into service. A number of planetary probes have been launched from Site 200. Venera 14, Venera 15, Vega 1, Fobos 1, the failed Mars-96, and ExoMars were launched from area 39. Venera 13, Venera 16, Vega 2, Fobos 2 were launched from Area 40. Area 39 was also the launch site for the core of the Mir space station A space station (or orbital station) is a spacecraft which remains orbital spaceflight, in orbit and human spaceflight, hosts humans for extended periods of time.

Nimiq
The Nimiq satellites are a Canadian fleet of geostationary telecommunications satellites owned by Telesat and used by satellite television providers including Bell Satellite TV and EchoStar (Dish Network). 'Nimiq' is an Inuit word used for an object or a force which binds things together. A contest in 1998 was held to choose the name of these satellites. The contest drew over 36,000 entries. Sheila Rogers, a physiotherapist from Nepean, Ontario, submitted the winning name. Nimiq-1 Nimiq-1 was launched on 21 May 1999 by a Proton-K / Blok DM-03 launch vehicle from Baikonur Cosmodrome in Kazakhstan. It was Canada's first direct broadcast digital TV satellite and was paid for by Telesat, a Canadian communications company and subsidiary of Bell Canada Enterprises. * Manufacturer: Lockheed Martin * Satellite Type: Lockheed Martin, A2100AX * Weight: * Dimensions: 5.8 x 2.4 x 2.4 m and a 27 m2 solar array * DC power: 120 W * Expected lifetime: 12 years * Transponders: 32 * V ...

Ekran
: ''For the Soviet animation studio see page Studio Ekran'' Ekran (, meaning ''"Screen"'') was a Soviet-Russian type of geostationary satellite, developed for a national system of Direct-To-Home television. The first satellite of Ekran series was launched on 26 October 1976. Each satellite in the Ekran series was designed to provide one TV and two radio program channels to cable TV systems throughout the USSR and to individual home receivers in northern Siberia. Ekran's downlink is in the Ultra high frequency (UHF) range. Early Ekran satellites used orbital positions in the range from 48° East to 95° East, but recent Ekran, including the current Ekran 20, have been stationed at 99° East. These 3-axis stabilized satellites carry a single 24 MHz, 200 watts transponder, feeding a 28 dB gain antenna transmitting on right-hand circular polarization to produce in Siberia in the range 50 to 55 dBW at 714 MHz. The corresponding feeder link uses left-hand circular polarizat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
