Kosmos 2474
Kosmos 2474 (russian: Космос 2474 meaning ''Cosmos 2474'') is a Russian military satellite launched in 2011 as part of the GLONASS satellite navigation system. This satellite is a GLONASS-M satellite, also known as Uragan-M, and is numbered Uragan-M No. 742. Kosmos 2474 was launched from Site 43/4 at Plesetsk Cosmodrome in northern Russia. A Soyuz-2-1b carrier rocket with a Fregat upper stage was used to perform the launch which took place at 20:15 UTC on 2 October 2011. The launch successfully placed the satellite into Medium Earth orbit. It subsequently received its Kosmos designation, and the international designator 2011-055A. The United States Space Command assigned them the Satellite Catalog Numbers 37829. It was due to be launched on 25 August 2011 but was postponed due to the failed launch of Progress M-12M the day before. It was rescheduled to 25 September, and then to 1 October before being launched on 2 October. It is in the first orbital plane used by GLONAS ...

Satellite Navigation
A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows satellite navigation devices to determine their location (longitude, latitude, and altitude/elevation) to high precision (within a few centimetres to metres) using time signals transmitted along a line of sight by radio from satellites. The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking). The signals also allow the electronic receiver to calculate the current local time to a high precision, which allows time synchronisation. These uses are collectively known as Positioning, Navigation and Timing (PNT). One set of critical vulnerabilities in satellite communications are the signals that govern positioning, navigation and timing (PNT). Failure to properly secure these transmissions could not only disrupt satellite networks but wreak havoc on a host of dependent s ...

Fregat
Fregat (russian: Фрегат, ''frigate'') is an upper stage developed by NPO Lavochkin in the 1990s, which is used in some Soyuz and Zenit launch vehicles, but is universal and can be used as a part of a medium and heavy class launch vehicles. Fregat became operational in February 2000. Its liquid propellant engine uses UDMH and N2O4. Fregat's success rate is 97.8% (with 2 failures in 93 launches), which makes it one of the most reliable upper stages in the world. Fregat has successfully delivered more than 300 payloads into different orbits. It remains the only upper stage in the world that can place its payload into 3 or more different orbits in a single launch. Description The Fregat upper stage is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit. Fregat is a versatile upper stage, in addition to orbital insertion, it can be used as an escape stage to send modern space probes into interplanetary trajectories (e.g. Venus Express ...

Spacecraft Launched In 2011
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific res ...

United States Space Command
United States Space Command (USSPACECOM or SPACECOM) is a unified combatant command of the United States Department of Defense, responsible for military operations in outer space, specifically all operations 100 kilometers (62 miles) and greater above mean sea level. U.S. Space Command is responsible for the operational employment of space forces that are provided by the uniformed services of the Department of Defense. Space Command was originally created in September 1985 to provide joint command and control for all military forces in outer space and coordinate with the other combatant commands. SPACECOM was disestablished in 2002, and its responsibilities and forces were merged into United States Strategic Command. A second incarnation of Space Command was established on 29 August 2019, with a reemphasized focus on space as a warfighting domain. Mission Space Command's mission is: ''"To conduct operations in, from, and through space to deter conflict, and if necessary, defe ...

International Designator
The International Designator, also known as COSPAR ID, is an international identifier assigned to artificial objects in space. It consists of the launch year, a three-digit incrementing launch number of that year and up to a three-letter code representing the sequential identifier of a piece in a launch. In TLE format the first two digits of the year and the dash are dropped. For example1990-037Ais the Space Shuttle ''Discovery'' on mission STS-31, which carried the Hubble Space Telescope1990-037B into space. This launch was the 37th known successful launch worldwide in 1990. The designation system has been generally known as the COSPAR system, named for the Committee on Space Research (COSPAR) of the International Council for Science. COSPAR subsumed the first designation system, devised at Harvard University. That system used letters of the Greek alphabet to designate artificial satellites. This was based on the scientific naming convention for natural satellites. For exampl ...

Kosmos (satellite)
Kosmos (russian: Ко́смос, , meaning " (outer) space" or " Kosmos") is a designation given to many satellites operated by the Soviet Union and subsequently Russia. Kosmos 1, the first spacecraft to be given a Kosmos designation, was launched on 16 March 1962. History The first Soviet satellites orbiting Earth were named Sputnik, Polyot (starting in 1963), Elektron (in 1964), Proton (in 1965), and Molniya (in 1965), but most have been called Kosmos since Kosmos 1 on 16 March 1962. The program has included uncrewed tests of crewed spacecraft and satellites for scientific research and military purposes. , 2548 Kosmos satellites have been launched. The spacecraft do not form a single programme, but instead consist of almost all Soviet and Russian military satellites, as well as a number of scientific satellites, and spacecraft which failed during or immediately after launch, but still reached orbit. Most Soviet and subsequently Russian military satellites were given Kosm ...

GLONASS
GLONASS (russian: ГЛОНАСС, label=none, ; rus, links=no, Глобальная навигационная спутниковая система, r=Global'naya Navigatsionnaya Sputnikovaya Sistema, t=Global Navigation Satellite System) 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. GLONASS supplementation of GPS systems also improves positioning in high latitudes (north or south). Development of GLONASS began in the Soviet Union in 1976. Beginning on 12 October 1982, numerous rocket launches added satellites to the system, unti ...

Russian Space Forces
The Russian Space Forces ( rus, Космические войска России, Kosmicheskie voyska Rossii, KV) are a branch of the Russian Aerospace Forces, that provides aerospace warning, air and space sovereignty, and other related protection for Russia. Having been reestablished following August 1, 2015 merger between the Russian Air Force and the Russian Aerospace Defence Forces after the independent arm of service was dissolved in 2011. The Russian Space Forces were originally formed on August 10, 1992, alongside the creation of the Russian Armed Forces. The organization shared control of the Baikonur Cosmodrome with Roscosmos, the Federal Space Agency. It also operated the Plesetsk and the Svobodny Cosmodromes. However the Russian Space Forces were dissolved in July 1997 and incorporated into the Strategic Missile Forces. The Russian Space Forces were once again reformed as an independent troop on June 1, 2001, under a military reorganization. However, by December 2011 ...
