Videometer
A videometer is a European designed automatic docking system that guides an Automated Transfer Vehicle (ATV) towards the docking port of the Russian Zvezda Service Module of the International Space Station (ISS).{{cite news, title=State of the art in automatic rendezvous, url=http://www.esa.int/esaMI/ATV/SEMZ2O57ESD_0.html, publisher=European Space Agency, date=2 April 2004 The ATV uses relative global positioning system (GPS) in order to close in on the ISS up to a distance of 249 m. Thereafter the ATV uses two videometers, together with additional data from telegoniometer A Telegoniometer (a type of goniometer) is a device for varying the phase relationship(s) among two or more antennae in an array. This is for steering the directionality of the array without physically moving the antennae. the telegoniometer is ...s, to automatically complete the docking maneuver. Both videometers are active during rendezvous with one acting as a back-up. Retroreflectors located on the aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automated Transfer Vehicle
The Automated Transfer Vehicle, originally Ariane Transfer Vehicle or ATV, was an expendable automated cargo spacecraft, cargo spacecraft developed by the European Space Agency (ESA), used for space cargo transport in 2008–2015. The ATV design was launched to orbit five times, exclusively by the Ariane 5 heavy-lift launch vehicle. It effectively was a larger European counterpart to the Russian Progress (spacecraft), Progress cargo spacecraft for carrying upmass to a single destination—the International Space Station (ISS)—but with three times the capacity. The five ATVs were named after important European figures in science and engineering: ''Jules Verne ATV, Jules Verne'', ''Johannes Kepler ATV, Johannes Kepler'', ''Edoardo Amaldi ATV, Edoardo Amaldi'', ''Albert Einstein ATV, Albert Einstein'', and ''Georges Lemaître ATV, Georges Lemaître''. Following several delays to the program, the first of these was launched in March 2008. These ATVs performed supply missions to t ...

Zvezda Service Module
''Zvezda'' (russian: Звезда, meaning "star"), ''Salyut'' DOS-8, also known as the ''Zvezda'' Service Module, is a module of the International Space Station (ISS). It was the third module launched to the station, and provided all of the station's life support systems, some of which are supplemented in the US Orbital Segment (USOS), as well as living quarters for two crew members. It is the structural and functional center of the Russian Orbital Segment (ROS), which is the Russian part of the ISS. Crew assemble here to deal with emergencies on the station. The module was manufactured in the USSR by RKK Energia, with major sub-contracting work by GKNPTs Khrunichev. ''Zvezda'' was launched on a Proton launch vehicle on 12 July 2000, and docked with the '' Zarya'' module on 26 July 2000. Origins The basic structural frame of ''Zvezda'', known as "DOS-8", was initially built in the mid-1980s to be the core of the ''Mir-2'' space station. This means that ''Zvezda'' is ...

International Space Station
The International Space Station (ISS) is the largest Modular design, modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), European Space Agency, ESA (Europe), and Canadian Space Agency, CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which Scientific research on the International Space Station, scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The International Space Station programme, ISS programme evolved from the Space Station Freedom, Space Station ''Freedom'', a 1984 American proposal to constr ...

Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telegoniometer
A Telegoniometer (a type of goniometer) is a device for varying the phase relationship(s) among two or more antennae in an array. This is for steering the directionality of the array without physically moving the antennae. the telegoniometer is commonly used for radio direction finding Direction finding (DF), or radio direction finding (RDF), isin accordance with International Telecommunication Union (ITU)defined as radio location that uses the reception of radio waves to determine the direction in which a radio statio ..., providing very precise bearings from a sensitive fixed site. A telegoniometer is simply a goniometer with remote control and readout. As an example, it is used on unmanned spacecraft for the long-range approach phase of automated docking, before more precise (but shorter-range) optical systems take over.
