Full title and description

Space data and information transfer systems — Telemetry (TM) channel coding profiles (ISO 17808:2014). This International Standard provides recommendations for the selection and use of telemetry channel coding schemes across mission profiles encountered in space research, space operations and Earth observation, and specifies expected behaviours of the Synchronization and Channel Coding sublayer at sender and receiver.

Abstract

ISO 17808:2014 presents recommended channel coding profiles for telemetry (TM) links used in space applications. It assumes a Synchronization and Channel Coding sublayer that accepts fixed‑length transfer frames from the Data Link sublayer, applies mission‑selected encoding and synchronization, and delivers a continuous stream of channel symbols to the Physical layer. At reception, the sublayer accepts a continuous stream of channel symbols, performs synchronization and decoding, and delivers transfer frames to the Data Link sublayer. The document offers guidance on which coding schemes are appropriate for different mission profiles and notes a number of out‑of‑scope link types (for example Earth‑to‑space and certain proximity or relay configurations).

Scope

ISO 17808:2014 recommends telemetry channel coding profiles for space‑to‑Earth and related TM links used in space research, operations and Earth observation. It defines expected functions and interfaces of the Synchronization and Channel Coding sublayer at both sender and receiver ends and maps coding choices to typical mission profiles. The standard explicitly excludes Earth‑to‑space and Proximity link profiles, and does not address certain communication profiles not covered by CCSDS (for example some relay or emerging link types).

Key topics and requirements

• Recommended channel coding schemes and profiles mapped to common mission classes (e.g., deep‑space, near‑Earth, low‑data‑rate, high‑reliability).
• Behavioral assumptions for the Synchronization and Channel Coding sublayer: acceptance of fixed‑length transfer frames, performance of encoding and synchronization, and delivery of a continuous stream of channel symbols to the Physical layer.
• Receiver requirements: acceptance of continuous channel symbol streams, synchronization and decoding functions, and delivery of transfer frames to the Data Link sublayer.
• Interoperability guidance to align with CCSDS telemetry synchronization and channel coding recommendations.
• Identification of out‑of‑scope link types (Earth‑to‑space, proximity links, and certain relay configurations) and guidance to consult other applicable standards for those cases.
• Reference to related telemetry, data link and space link protocol standards used when selecting coding and synchronization options.

Typical use and users

Engineers and architects designing spacecraft telemetry subsystems, ground segment and mission operations personnel, standards and compliance teams, system integrators and contractors working on space data links, and national/international standards bodies. Typical uses include selecting channel coding for new missions, verifying conformance of telemetry subsystems, and aligning vendor implementations with accepted profiles for interoperability.

Related standards

Standards commonly used alongside ISO 17808 include ISO 11754 (telemetry channel coding), ISO TM space data link protocol standards, CCSDS recommendations for TM synchronization and channel coding, Proximity‑1 and other space link protocol standards, and relevant European and national space‑engineering data link standards. Implementers often consult CCSDS TM and space link documents to apply the profiles in operational designs.

FAQ

Q: What is this standard?

A: ISO 17808:2014 is an International Standard titled "Space data and information transfer systems — Telemetry (TM) channel coding profiles" that provides recommended channel coding profiles and behavioral assumptions for the Synchronization and Channel Coding sublayer used in telemetry links for space applications.

Q: What does it cover?

A: It covers recommendations for selecting and applying telemetry channel coding schemes for various mission profiles, the expected sender and receiver behaviours of the Synchronization and Channel Coding sublayer, and guidance on interoperability. It excludes Earth‑to‑space and many proximity/relay link profiles.

Q: Who typically uses it?

A: Spacecraft communications engineers, ground station and mission operations teams, system integrators, and standards compliance groups use the standard to choose and validate telemetry channel coding for missions.

Q: Is it current or superseded?

A: ISO 17808 was published in July 2014 (Edition 1). Users should verify current status with their standards‑management source before procurement or certification, since standards are subject to periodic review and revision.

Q: Is it part of a series?

A: Yes. ISO 17808 sits within the ISO/TC 20/SC 13 portfolio of space data and information transfer systems and is used alongside other TM, space link and CCSDS documents that together form the suite of telemetry and space link standards.

Q: What are the key keywords?

A: Telemetry, TM, channel coding, synchronization, channel coding profiles, space data links, CCSDS, data link, space communications.
