Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.
The interplanetary Internet is a conceived computer network in space, consisting of a set of network nodes that can communicate with each other. These nodes are the planet's orbiters (satellites) and landers, and the earth ground stations. For example, the orbiters collect the scientific data from the Curiosity rover on Mars through near-Mars communication links, transmit the data to Earth through direct links from the Mars orbiters to the Earth ground stations, and finally the data can be routed through Earth's internal internet.
The Satellite Control and Operation System 2000 (SCOS-2000) is the generic satellite Mission Control System (MCS) software infrastructure developed and maintained by the European Space Agency (ESA/ESOC) in collaboration with European industry and deployed for missions such as Radarsat 2, XMM-Newton, INTEGRAL, Cryosat, Mars Express, Venus Express, GOCE, Herschel, Planck, Rosetta, Cryosat-2, Galileo, MetOp, LISA Pathfinder, SWARM, Gaia, SENTINEL spacecraft or EXOMARS orbiters. Upcoming missions that will deploy SCOS-2000 include MetOp-SG, METEOSAT Third Generation, Aeolus, EarthCARE, BepiColombo, SOLO or EUCLID.
TacSat-2 is the first in a series of U.S. military experimental technology and communication satellites.TacSat-2 (also known as JWS-D1 was an experimental satellite built by the USAF's Air Force Research Laboratory with an operational life expected to be not more than one year as part of the "Advanced Concept Technology Demonstration" program.
The Spacecraft Monitoring & Control (SM&C) Working Group of the Consultative Committee for Space Data Systems (CCSDS), which sees the active participation of the main space agencies, is defining a service-oriented architecture consisting of a set of standard end-to-end services between functions resident on board a spacecraft or based on the ground, that are responsible for mission operations.
The STAR-2 Bus is a fully redundant, flight-proven, spacecraft bus designed for geosynchronous missions.
The Spacecraft Monitoring & Control (SM&C) Working Group of the Consultative Committee for Space Data Systems, which sees the active participation of 10 space agencies and of the Space Domain Task Force of the Object Management Group, is defining a service-oriented architecture consisting of a set of standard end-to-end services between functions resident on board a spacecraft or based on the ground, that are responsible for mission operations.
Indian Deep Space Network (IDSN) is a network of large antennas and communication facilities operated by the Indian Space Research Organisation to support the interplanetary spacecraft missions of India. Its hub is located at Byalalu, Ramanagar in the state of Karnataka in India. It was inaugurated on 17 October 2008 by the former ISRO chairman G. Madhavan Nair.
EPUB is an e-book file format that uses the ".epub" file extension. The term is short for electronic publication and is sometimes styled ePub. EPUB is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. EPUB is a technical standard published by the International Digital Publishing Forum (IDPF). It became an official standard of the IDPF in September 2007, superseding the older Open eBook standard.
SSETI Express was the first spacecraft to be designed and built by European students and was launched by the European Space Agency. SSETI Express is a small spacecraft, similar in size and shape to a washing machine. On board the student-built spacecraft were three CubeSat picosatellites, extremely small satellites weighing around one kg each. These were deployed one hour and forty minutes after launch. Twenty-one university groups, working from locations spread across Europe and with very different cultural backgrounds, worked together via the internet to jointly create the satellite. The expected lifetime of the mission was planned to be 2 months. SSETI Express encountered an unusually fast mission development: less than 18 months from kick-off in January 2004 to flight-readiness.

The Consultative Committee for Space Data Systems (CCSDS) was founded in 1982 for governmental and quasi-governmental space agencies to discuss and develop standards for space data and information systems. Currently composed of "eleven member agencies, twenty-eight observer agencies, and over 140 industrial associates," the CCSDS works to support collaboration and interoperability between member agencies through the establishment of data and system standards. According to the organisation's website, more than 1000 space missions have utilized data and systems standards created by CCSDS. The activities of the CCSDS are organized around six topic areas and composed of many working groups within the overall Collaborative Working Group Environment (CWE).
OPS-SAT is a CubeSat by the European Space Agency (ESA) and it is intended to demonstrate the improvements in mission control capabilities that will arise when satellites can fly more powerful on-board computers. The mission has the objective to break the cycle of "has never flown, will never fly" in the area of satellite control. It was the first CubeSat operated directly by ESA.
SpaceOps is an international committee organisation formed in 1992 to "promote and maintain an international community of space operations experts".
A ground segment consists of all the ground-based elements of a spacecraft system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground. The primary elements of a ground segment are:
The NanoSat MO Framework (NMF) is a software framework for nanosatellites based on CCSDS Mission Operations services. It facilitates not only the monitoring and control of the nanosatellite software applications, but also the interaction with the nanosatellite platform. This is achieved by using the latest CCSDS standards for monitoring and control, and by exposing services for common peripherals among nanosatellite platforms. Furthermore, it is capable of managing the software on-board by exposing a set of services for software management.
Telespazio Germany GmbH is a European aerospace company, founded in 1978. The company provides consulting, technology and engineering services in aerospace missions for ESOC, EUMETSAT and the German Aerospace Center (DLR).
A spacecraft command language is a computer command language for commanding spacecraft mission systems. Ultimately such languages are used to command remote spacecraft with telecommands, but they are also used for development and verification of onboard systems, and of ground systems, prior to launch.
