CCSDS Mission Operations
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. Identification of the problem There is a general trend toward increasing mission complexity at the same time as increasing pressure to reduce the cost of mission operations, both in terms of initial deployment and recurrent expenditure. Closed, or ‘monolithic’ mission operations system architectures do not allow the re-distribution of functionality between space and ground, or between nodes of the ground system. This lack of architectural openness leads to: * lack of interoperability between agencies; * lack of re-use between missions and ground systems; * increased cost of mission spe ...

NanoSat MO Framework
The NanoSat MO Framework (NMF) is a software framework for Miniaturized_satellite, nanosatellites based on CCSDS_Mission_Operations, CCSDS Mission Operations services. It was developed by Graz University of Technology in partnership with the European Space Agency. The framework facilitates the monitoring and control of the nanosatellite software applications as well as 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. Installed apps onboard can be started and stopped from ground via the NMF. Apps can retrieve data from the nanosatellite platform through a set of platform services. Additionally, it includes CCSDS standardized services for monitoring and control of apps. An NMF App can be developed, distribute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consultative Committee For Space Data Systems
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). Publications and standards The CCSDS is divided into 6 Technical areas: * Space Internetworking Services * Mission Operations And Information Management Services * Spacecraft Onboard Interface Services * System Engineering * Cross Sup ...

Service-oriented Architecture
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. By consequence, it is also applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies. Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services. A service has four properties according to one of many definitions of SOA: # It logically represents a repeatable business activity with a specified outcome. # It is self-contained. # It is a black box for its consumers, meaning the consumer does not have to be aware of the s ...

Ground Segment
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: * Ground (or Earth) stations, which provide radio interfaces with spacecraft * Mission control (or operations) centers, from which spacecraft are managed * Remote terminals, used by support personnel * Spacecraft integration and test facilities * Launch facilities * Ground networks, which allow for communication between the other ground elements These elements are present in nearly all space missions, whether commercial, military, or scientific. They may be located together or separated geographically, and they may be operated by different parties. Some elements may support multiple spacecraft simultaneously. Elements Groun ...

Space Standards
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "space ...
