Space data and information transfer systems — The data description language EAST specification

Space data and information transfer systems — The data description language EAST specification

ISO 15889:2011 defines the Enhanced Ada SubseT (EAST) language used to create descriptions of data called Data Description Records (DDRs). Such DDRs ensure a complete and exact understanding of the data and allow it to be interpreted in an automated fashion. This means that a software tool is able to analyse a DDR and interpret the format of the associated data. This allows the software to extract values from the data on any host machine (i.e. on a different machine from the one that produced the data).

ISO 15889:2011(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
This third edition cancels and replaces the second edition (ISO 15889:2003), which has been technically
revised.
ISO 15889 was prepared by the Consultative Committee for Space Data Systems (CCSDS) as
CCSDS 644.0-B-3, June 2010 and was adopted without modifications except those stated in Clause 2 of this
International Standard by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13,
Space data and information transfer systems.

of data called Data Description Records (DDRs). Such DDRs ensure a complete and exact understanding of
the data and allow it to be interpreted in an automated fashion. This means that a software tool is able to
analyse a DDR and interpret the format of the associated data. This allows the software to extract values from
the data on any host machine (i.e. on a different machine from the one that produced the data).
The scope and field of application are furthermore detailed in subclauses 1.1 and 1.2 of the enclosed CCSDS
publication.
2 Requirements
Requirements are the technical recommendations made in the following publication (reproduced on the
following pages), which is adopted as an International Standard:
CCSDS 644.0-B-3, June 2010, The data description language EAST specification.
For the purposes of international standardization, the modifications outlined below shall apply to the specific
clauses and paragraphs of publication CCSDS 644.0-B-3.

Space data and information transfer systems — Digital motion imagery

The purpose of this document is to provide a common reference and framework of standards for digital motion video and imagery, and to provide recommendations for utilization of international standards for sharing or distributing motion video and imagery between spacecraft elements and ground systems. The scope of this document includes traditional real-time streaming video and television, including human and robotic spacecraft-to-spacecraft and spacecraft-to-ground systems, as well as video recorded and distributed later, either as a real-time stream or as a file transfer. In this context, real-time streaming includes all modes where video is sent from a spacecraft in a continuous stream and is intended for immediate use when received, regardless of the latency of the transmission path. Other specialized motion imagery applications, such as high-speed scientific motion imagery and multi-spectral motion imagery, are not addressed in this document. However, if a specialized imagery camera system has a requirement to interface to spacecraft systems in a video mode, it would be required to match these interfaces. Ground-systems-to-ground-systems video distribution is obviously a key component of the entire video system. However, this is not the primary focus of this document. Currently, there are significant differences in the ways mission video products are exchanged between the various space agencies on the ground. This is the result of differences in network topologies between space agencies, and agreements for video sharing. Those differences preclude there being a standard methodology for delivering video imagery between agencies. Prior to the commencement of video transmission between space agencies, system design reviews and performance testing should be done between the ground systems in use to assure operability when video imagery comes from spacecraft.

Space data and information transfer systems — Space link extension (SLE) — Return-channel-frames service specification

The purpose of this document is to define the Space Link Extension (SLE) Return Channel Frames (RCF) service in conformance with the SLE Reference Model (reference [1]). The RCF service is an SLE transfer service that delivers to a mission user all telemetry frames from one master channel or one virtual channel. This document defines, in an abstract manner, the RCF service in terms of: the operations necessary to provide the service; the parameter data associated with each operation; the behaviors that result from the invocation of each operation; and the relationship between, and the valid sequence of, the operations and resulting behaviors. It does not specify: individual implementations or products; the implementation of entities or interfaces within real systems; the methods or technologies required to acquire telemetry frames from signals received from a spacecraft; the methods or technologies required to provide a suitable environment for communications; or the management activities required to schedule, configure, and control the RCF service. NOTE – Reference [1] defines the Return Master Channel Frames (Rtn MC Frames) service and the Return Virtual Channel Frames (Rtn VC Frames) service as two distinct services. Subsequent study has indicated that it is preferable to define one service that provides the functionality of both. The RCF service defined here does just that. It is anticipated that a future issue of reference [1] will take the same approach, deleting the Rtn MC Frames and Rtn VC Frames services and replacing them with the RCF service.

Space data and information transfer systems — Space link extension (SLE) — Forward space packet service specification

This document defines the Forward Space Packet (FSP) service in conformance with the transfer services specified in reference [1], Cross Support Reference Model―Part 1: SLE Services. The FSP service is a Space Link Extension (SLE) transfer service that enables a mission to send Space Packets to a spacecraft in sequence-controlled or expedited mode. This document defines, in an abstract manner, the FSP service in terms of: the operations necessary to provide the transfer service; the parameter data associated with each operation; the behaviors that result from the invocation of each operation; and the relationship between, and the valid sequence of, the operations and resulting behaviors. It does not specify: individual implementations or products; the implementation of entities or interfaces within real systems; the methods or technologies required to radiate Space Packets to a spacecraft and to acquire telemetry frames from the signals received from that spacecraft for extraction of the Operational Control Field; the methods or technologies required for communications; or the management activities necessary to schedule, configure, and control the FSP service. NOTE – While the FSP service as described in reference [1] is conceived to handle a variety of packet data structures, this version of the FSP Recommended Standard is restricted to the handling of Space Packets as defined in reference [6]. This version of the FSP Recommended Standard is specific to the transfer of Space Packets to be transmitted via the Telecommand protocol stack as defined in references [3], [4], and [5]. The Cross Support Reference Model (reference [1]) specifies that the FSP service may also be used in conjunction with the Advanced Orbiting System protocol stack, but that mode of operation is outside the scope of this version of the Recommended Standard. The FSP service is provided in the online delivery mode, as defined in reference [1]. The offline delivery mode is the subject of further study.

Space data and information transfer systems — Attitude data messages

This document specifies two standard message formats for use in transferring spacecraft attitude information between space agencies: the Attitude Parameter Message (APM) and the Attitude Ephemeris Message (AEM). Such exchanges are used for: - preflight planning for tracking or attitude estimation support; - scheduling attitude and data processing support; - carrying out attitude operations; - performing attitude comparisons; - carrying out attitude propagations and/or sensor predictions; - testing to initialize sub-system simulators (communications, power, etc.). This document includes sets of requirements and criteria that the message formats have been designed to meet. For exchanges where these requirements do not capture the needs of the participating agencies, another mechanism may be selected.

Space data and information transfer systems — Space link extension — Application program interface for transfer services — Core specification

This document defines the Application Program Interface in terms of: the components that provide the services of the API; the functionality provided by each of the components; the interfaces provided by each of the components; and the externally visible behavior associated with the interfaces exported by the components. It does not specify: individual implementations or products; the internal design of the components; and the technology used for communications. This document defines those aspects of the Application Program Interface, which are common for all SLE service types or for a subset of the SLE service types, e.g., all return link services or all forward link services. It also defines a framework for specification of service type-specific elements of the API. Service-specific aspects of the API are defined by supplemental Recommended Practice documents for SLE return link services (references [10], [11], and [12]) and SLE forward link services (references [13] and [14]). This document for the Application Program Interface responds to the requirements imposed on such an API by the CCSDS SLE transfer service Recommended Standards that were available when this document was released.
