picture info	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 ...

	X Band Satellite Communication X band or SHF Satellite Communication is widely used by military forces for beyond line of sight communications. X band is used because it provides a compromise between the characteristics of different frequency bands which is particularly suited to the needs of military users. The characteristics include interference and rain resilience, terminal size, data rates, remote coverage and whether it is reserved for governmental use. Characteristics of the SHF frequency band Frequency x Band Satellite Communication operates in the part of the X band or Super High Frequency (SHF) spectrum which is designated by the International Telecommunication Union (ITU) for satellite communication, which is those frequencies in the range 7.25 GHz to 7.75 GHz (Space to Earth) and 7.9 GHz to 8.4 GHz (Earth to Space). The ITU Frequency allocation defines the primary use of this spectrum as Fixed satellite service (FSS) and a portion to Mobile Satellite Services (MSS), primaril ...

	Turkish Satellite Assembly, Integration And Test Center Turkish Space Systems, Integration and Test Centre ( tr, Uzay Sistemleri, Entegrasyon ve Test Merkezi) (USET) is a spacecraft production and testing facility owned by the Ministry of National Defence and operated by Turkish Aerospace Industries (TAI). It is located in Ankara, Turkey. The facility's official inauguration took place on May 21, 2015 in presence of President Recep Tayyip Erdoğan. Considered as a critical infrastructure, the centre was established within the framework of the Göktürk-1 project, which started in 2009, for the indigenous realization of satellite assembly, as well as for qualification and acceptance testing from design to launch phase. It was the product of an agreement between the Turkish Ministry of National Defence and the multinational space services company Telespazio in 2010. Situated within TAI's grounds in the Kazan district of Ankara Province, the budgeted cost of the facility is US$100 million. USET is a technology centre, at which all sate ...

	On-board Data Handling The on-board data handling (OBDH) subsystem of a spacecraft is the subsystem which carries and stores data between the various electronics units and the ground segment, via the telemetry, tracking and command (TT&C) subsystem. In the earlier decades of the space industry, the OBDH function was usually considered a part of the TT&C, particularly before computers became common on board. In recent years, the OBDH function has expanded, so much that it is generally considered a separate subsystem to the TT&C, which is these days concerned solely with the RF link between the ground and the spacecraft. Functions commonly performed by the OBDH are: * Reception, error correction and decoding of telecommands (TCs) from the TT&C * Forwarding of telecommands for execution by the target Avionics * Storage of telecommands until a defined time ('time tagged' TCs) * Storage of telecommands until a defined position ('position tagged' TCs) * Measurement of discrete values such as voltages, tempe ...

picture info	Software Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Spacecraft Thermal Control In spacecraft design, the function of the thermal control system (TCS) is to keep all the spacecraft's component systems within acceptable temperature ranges during all mission phases. It must cope with the external environment, which can vary in a wide range as the spacecraft is exposed to the extreme coldness found in the shadows of deep space or to the intense heat found in the unfiltered direct sunlight of outer space. A TCS must also moderate the internal heat generated by the operation of the spacecraft it serves. A TCS can eject heat passively through the simple and natural infrared radiation of the spacecraft itself, or actively through an externally mounted infrared radiation coil. Thermal control is essential to guarantee the optimal performance and success of the mission because if a component is subjected to temperatures which are too high or too low, it could be damaged or its performance could be severely affected. Thermal control is also necessary to keep specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Spacecraft Design The design of spacecraft covers a broad area, including the design of both robotic spacecraft (satellites and planetary probes), and spacecraft for human spaceflight ( spaceships and space stations). Origin Spacecraft design was born as a discipline in the 1950s and 60s with the advent of American and Soviet space exploration programs. Since then it has progressed, although typically less than comparable terrestrial technologies. This is for a large part due to the challenging space environment, but also to the lack of basic R&D, and to other cultural factors within the design community. On the other hand, another reason for slow space travel application design is the high energy cost, and low efficiency, for achieving orbit. This cost might be seen as too high a "start-up-cost." Areas of engineering involved Spacecraft design brings together aspects of various disciplines, namely: * Astronautics for mission design and derivation of the design requirements, * Systems engine ...
