Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsiklon (satellite)
Tsiklon (meaning cyclone, ) is the first Soviet satellite navigation system, developed in the former Soviet Union. From 1967 to 1978 a total of 31 Zaliv satellites were launched onboard Kosmos-3 and Kosmos-3M rockets, from the Kapustin Yar and Plesetsk launch sites. The project was conceived in the 1950s and the draft proposal was approved in 1962, but was not made operational until 1972 due to delays.Tsiklon astronautix.com The successor satellites to Tsiklon were Parus and Sfera.

Kapustin Yar
Kapustin Yar () is a Russian military training area and a rocket launch complex in Astrakhan Oblast, about 100 km east of Volgograd. It was established by the Soviet Union on 13 May 1946. In the beginning, Kapustin Yar used technology, material, and scientific support gained from the defeat of Nazi Germany in World War II. Numerous launches of test rockets for the Russian military were carried out at the site, as well as satellite and sounding rocket launches. The towns of Znamensk, Astrakhan Oblast, Znamensk and Kapustin Yar (air base), Kapustin Yar were built nearby to serve the missile test range. Name The nearby village, Kapustin Yar, was used as the operations base in the early days of the testing site. The name can be translated as "cabbage ravine". In public opinion, Kapustin Yar has been compared to as the "Russian Roswell UFO incident, Roswell"; the place where the USSR discovered, investigated or captured alien ships (UFOs). Due to its role as a development site fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DS-P1-Yu
DS-P1-Yu was a series of Soviet satellites developed by the Yuzhnoye Design Office, for use in calibrating the Dnestr space surveillance and early-warning radar system. Between 1964 and 1976, a total of 79 satellites were launched on Kosmos and Kosmos-2I launchers, with seven failing to reach orbit. The dodecahedral satellites had a mass of and an operational lifetime of 60 days. They were covered in solar panels and a metallic mesh transparent to visible spectrum The visible spectrum is the spectral band, band of the electromagnetic spectrum that is visual perception, visible to the human eye. Electromagnetic radiation in this range of wavelengths is called ''visible light'' (or simply light). The optica ... light and opaque to radio frequencies. The DS-P1-Yu replaced the similar DS-P1, of which four were launched between 1962 and 1964, with one failure to reach orbit. References Soviet military spacecraft {{USSR-spacecraft-stub ...

Kosmos 545
Kosmos 545 ( meaning ''Cosmos 545''), known before launch as DS-P1-Yu No.62, was a Soviet satellite which was launched in 1973 as part of the Dnepropetrovsk Sputnik programme. It was a spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests. Launch Kosmos 545 was successfully launched into low Earth orbit at 11:44:50 UTC on 24 January 1973. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket. Orbit Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1973-004A. The North American Aerospace Defense Command assigned it the catalogue number 06348. Kosmos 545 was the sixtieth of seventy nine DS-P1-Yu satellites to be launched, and the fifty-fourth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of , an apogee of , 70.9 degrees of inclin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosmos-2I
The Kosmos (also spelled Cosmos, Russian: ) rockets were a series of Soviet and subsequently Russian rockets, derived from the R-12 and R-14 missiles, the best known of which is the Kosmos-3M, which has made over 440 launches. The Kosmos family contained a number of rockets, both carrier rockets and sounding rockets, for orbital and sub-orbital spaceflight respectively. The first variant, the Kosmos, first flew on 27 October 1961. Over 700 Kosmos rockets have been launched overall. Variants Based on the R-12 Kosmos Kosmos ( GRAU Index: 63S1, also known as Cosmos), was the name of a Soviet space rocket model active between 1961 and 1967. Kosmos was developed from the R-12 medium-range missile. It was launched a total of 38 times, with twelve failures. Kosmos-2M The Kosmos-2M (GRAU Index: 63S1M, also known as Cosmos-2M) rocket was the prototype preceding the Kosmos-2I rocket. It launched the Kosmos 106 and Kosmos 97 satellites, from Area 86 at Kapustin Yar. Kosmo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ELINT
Signals intelligence (SIGINT) is the act and field of intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis (to decipher the messages). Traffic analysis—the study of who is signaling to whom and in what quantity—is also used to integrate information, and it may complement cryptanalysis. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmissions. Since the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tselina-O
Tselina () were a series of military SIGINT satellites originally developed in the former Soviet Union and used in the past Russian military. These satellites could pinpoint the exact location of objects emitting radio signals. They could even identify the type of emitter, its operational modes, and its activity level. This function proved valuable for detecting potential military operations by monitoring increased radio communication activity. By providing early warning of such activity, Tselina offered valuable intel that might not have been obtainable through other means. Variants Initially divided into "Overview" (Tselina-O) and "Detailed" (Tselina-D), since about 1980 the system has been integrated into a single satellite, Tselina-P, which is also known as Tselina-2. The system's primary subject was enemy's radar equipment. Tselina had been numbered as part of the Kosmos series. In total 130 Tselina satellites were launched. * Tselina-O satellites were launched using K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
