Consultative Committee for Space Data Systems

Last updated

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. [1] 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). [2]

Publications and standards

The CCSDS is divided into 6 Technical areas: [3]

The CCSDS has developed data standards and information system frameworks covering a variety of areas including data creation, transmission, management, and preservation as well as the systems supporting that data. These include protocols and network notes for communication in space including contributions to Interplanetary Internet and Space Communications Protocol Specifications. Other standards include XML Telemetric and Command Exchange and frameworks such as the Mission Operations Services Concept [4] and the Open Archival Information System, [5] the latter a model also adopted by the broader Digital preservation and Data curation community.

Some of the Standards developed by the CCSDS are:

Membership

Each nation participating in the CCSDS can have one organization serve as a member agency. The current 11 member agencies in the CCSDS are: [6]

<span class="mw-page-title-main">Interoperability</span> Ability of systems to work with each other

Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance.

<span class="mw-page-title-main">Telemetry</span> Data and measurements transferred from a remote location to receiving equipment for monitoring

Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots tele, 'remote', and metron, 'measure'. Systems that need external instructions and data to operate require the counterpart of telemetry: telecommand.

The Organization for the Advancement of Structured Information Standards is a nonprofit consortium that works on the development, convergence, and adoption of open standards for cybersecurity, blockchain, Internet of things (IoT), emergency management, cloud computing, legal data exchange, energy, content technologies, and other areas.

<span class="mw-page-title-main">Interplanetary Internet</span> Model of Internet between planets

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 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 routed through Earth's internal internet.

The Schools Interoperability Framework, Systems Interoperability Framework (UK), or SIF, is a data-sharing open specification for academic institutions from kindergarten through workforce. This specification is being used primarily in the United States, Canada, the UK, Australia, and New Zealand; however, it is increasingly being implemented in India, and elsewhere.

In computer networking, out-of-band data is the data transferred through a stream that is independent from the main in-band data stream. An out-of-band data mechanism provides a conceptually independent channel, which allows any data sent via that mechanism to be kept separate from in-band data. The out-of-band data mechanism should be provided as an inherent characteristic of the data channel and transmission protocol, rather than requiring a separate channel and endpoints to be established. The term "out-of-band data" probably derives from out-of-band signaling, as used in the telecommunications industry.

An Open Archival Information System is an archive, consisting of an organization of people and systems, that has accepted the responsibility to preserve information and make it available for a Designated Community. The OAIS model can be applied to various archives, e.g., open access, closed, restricted, "dark", or proprietary.

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, EXOMARS orbiters, METEOSAT Third Generation, Aeolus, BepiColombo, SOLO or EUCLID. Upcoming missions that will deploy SCOS-2000 include MetOp-SG and EarthCARE.

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.

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, Ramanagara in the state of Karnataka in India. It was inaugurated on 17 October 2008 by the former ISRO chairman G. Madhavan Nair.

The Emergency Data Exchange Language (EDXL) is a suite of XML-based messaging standards that facilitate emergency information sharing between government entities and the full range of emergency-related organizations. EDXL standardizes messaging formats for communications between these parties. EDXL was developed as a royalty-free standard by the OASIS International Open Standards Consortium.

The beacon mode service is a Consultative Committee for Space Data Systems (CCSDS) telecommunications service aimed at spacecraft which are not communicated with via NASA's Deep Space Network. It is primarily designed to relay a spacecraft's "health" information, and secondarily its telecommunications status, using a simple signal that can be detected with a moderately-sized antenna. Beacon mode also enables spacecraft to communicate with one another on a daily basis, allowing for one spacecraft to act as a data proxy for another.

Svalbard Satellite Station or SvalSat is a satellite ground station located on Platåberget near Longyearbyen in Svalbard, Norway. Opened in 1997, it is operated by Kongsberg Satellite Services (KSAT), a joint venture between Kongsberg Defence & Aerospace and the Norwegian Space Centre (NSC). SvalSat and KSAT's Troll Satellite Station (TrollSat) in Antarctica are the only ground stations that can see a low altitude polar orbiting satellite on every revolution as the Earth rotates. As of 2021, the facility consists of 100 multi-mission and customer-dedicated antennas which operate in the C, L, S, X and K bands. The station provides ground services to more satellites than any other facility in the world.

A ground segment consists of all the ground-based elements of a space 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:

XTCE is an XML based data exchange format for spacecraft telemetry and command meta-data. Using XTCE the format and content of a space systems command and telemetry links can be readily exchanged between spacecraft operators and manufacturers. XTCE was originally standardized by the OMG. In April 2007 the OMG released revision 1.1 of XTCE as an OMG available specification. Version 1.0 of the XTCE specification is a CCSDS green-book specification and version 1.1 has been adopted as a CCSDS blue-book specification.
