Telecommand Summary of Concept and Rationale . Green Book. Issue 6. January 1987.
In order to establish a common framework within which the Agencies may develop standardized telecommand services, the CCSDS advocates adoption of a layered systems architecture. Within this approach, specific layers of service (including their operational protocol and data structuring techniques) may be selected for implementation according to mission requirements. The current layered set of CCSDS telecommand Recommendations was developed to match the conventional free-flying mission environment, as characterized by the transmission of command data at relatively low uplink data rates to spacecraft of moderate complexity. This Report summarizes the principal concepts associated with the CCSDS recommended space mission telecommanding architecture.

An OAIS 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. It meets a set of such responsibilities as defined in this document and this allows an OAIS archive to be distinguished from other uses of the term ‘archive’. The model provides a framework for the understanding and increased awareness of archival concepts needed for long-term digital information preservation and access, and for describing and comparing architectures and operations of existing and future archives. It also guides the identification and production of OAIS related standards.

XML Telemetric and Command Exchange (XTCE) . Blue Book. Issue 1. October 2007.
The XTCE data specification provides an information model and data exchange format for telemetry and commanding definitions (operational database) in all phases of the a spacecraft, payload, and ground segment life cycle: system design, development, test, validation, and mission operations.

XML Telemetric and Command Exchange (XTCE) . Green Book. Issue 1. July 2006.
This CCSDS Informational Report presents a set of concepts and tutorial on the XML Telemetric and Command Exchange (XTCE). XTCE is an XML based format aim at facilitating the exchange of spacecraft telemetry and command databases between different organizations and systems during any mission phase. Such a non-proprietary format avoids the need for customized import/export tools, and the validation and new implementation of mission databases, which are often error-prone. The scope of XTCE is limited to the exchange of satellite telemetry and commanding databases. XTCE can be used to exchange a database between spacecraft manufacturers, instrument manufacturers, and different systems of the ground segment. It can also be used as an exchange mechanism between different development teams or between missions, which enhances database re-use.

Space Communications Protocol Specification (SCPS)--Transport Protocol . Blue Book. Issue 2. October 2006.
The four Space Communications Protocol Specification (SCPS) Recommendations define a protocol suite that is parallel in function to, and interoperable with, the protocols of the Earth-based Internet (FTP/TCP/IP).  The SCPS protocols have been optimized to overcome problems associated with using Internet protocols in space. This Recommendation defines the transport-la
