Yamal-601
Yamal-601 (Russian: ) is a Russian geostationary communications satellite ordered by Gazprom Space Systems from Thales Alenia Space (TAS) on the Spacebus-4000C4 satellite bus for its Yamal programme. The satellite has mass of and 11 kW of payload power with over 15 years of design life. Its payload was also supplied by Thales Alenia Space and is composed of 38 C-band and 32 Ka-band transponders. It replaced Yamal-202 on 49° East as Yamal-202 was slated to reach its end of service around 2019. History In 2013, Gazprom Space Systems Board decided on a new plan. It required two new spacecraft: Yamal-501 and Yamal-601. In January 2014, Gazprom and Thales announced a contract for a new spacecraft, Yamal-601. In 2015, the Yamal-401 history would repeat itself, and the contract of Yamal-601 with Thales was cancelled and was reassigned to ISS Reshetnev, but Thales was again allowed to keep the payload supply. However, in 2016, this decision to give the spacecraft bus developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamal (satellite Constellation)
Yamal (russian: Яма́л) is a communication and broadcasting system developed and operated by Gazprom Space Systems. Born out of the connectivity needs of the natural gas extraction giant Gazprom, the system was spun off in its own company, and opened the network to third parties and even went into the public broadcasting industry. Yamal and Russian Satellite Communications Company (RSCC)'s Ekspress constellation are the only two national satellite operators in Russia. History During 1997, even before the launch of their first satellites ( Yamal 101 and Yamal 102), Gazkom was planning the second generation. At that time, they planned 24 satellites of the second generation. This extremely aggressive plan was scaled back by 2001 with a plan to launch four 200 series satellites. The first two, Yamal 201 and Yamal 202 planned to be launched by 2001 and the second pair, Yamal 203 and Yamal 204 by 2004. Yamal 201 and Yamal 203 were identical and be positioned at the 90° East ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yamal-401
Yamal-401 (russian: Ямал-401) is a Russian geostationary communications satellite operated by Gazprom Space Systems. It was built by ISS Reshetnev and is based on the Ekspress-2000 satellite bus. It is equipped with 17 C-band and 36 Ku-band transponders. It has a design life of 15 years. Development history In February 2009, Gazprom ordered two Yamal-400 type satellites from Thales Alenia Space. The satellites were name Yamal-401 and Yamal-402. Thales Alenia Space was to be responsible for all aspects of the development and building of the satellites. Both satellites were to be based on Spacebus4000C3 satellite buses. However, in 2010, Gazprom changed their satellite order so that the Yamal-401 satellite would be developed by ISS Reshetnev and be based on their Ekspress-2000 satellite bus. Thales Alenia Space would deliver the payload for Yamal-401 as originally agreed (also, no changes on the payload side of things). There were no changes with the Yamal-402 satellite ...

Communications Satellite
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 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. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Spacecraft Launched In 2019
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellites Using The Ekspress Bus
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Transponder (satellite Communications)
A communications satellite's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: * an input band-limiting device (an input band-pass filter), * an input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station (normally very weak, because of the large distances involved), * a frequency translator (normally composed of an oscillator and a frequency mixer) used to convert the frequency of the received signal to the frequency required for the transmitted signal, * an output band-pass filter, * a power amplifier (this can be a traveling-wave tube or a solid-state amplifier). Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Most transponders operate on a ...

Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SPUTNIX TabletSat * ...
