Overview - EN 16603-50-22:2022 (TM Space Data Link Protocol)

EN 16603-50-22:2022 is a CEN adoption notice that incorporates CCSDS 132.0-B-2 (TM Space Data Link Protocol) into the ECSS system with a minimum set of modifications. It standardizes the data link layer used for efficient transfer of telemetry (TM) application data over space links and defines how the CCSDS TM Transfer Frame is applied within ECSS/European space projects. This Adoption Notice, together with EN 16603-50-23, supersedes EN 16603-50-03:2014.

Key topics and technical requirements

• Adoption of CCSDS 132.0-B-2: The standard applies CCSDS Issue 2 (Sept. 2015) with specific ECSS adjustments to ensure consistent reference and integration.
• TM Transfer Frame compatibility: The TM Transfer Frame is aligned with ECSS transfer-frame concepts; notable modifications are listed in Clause 4 and an informative Annex A documents other differences.
• Extended virtual channel frame count: New requirements introduce a Transfer Frame Secondary Header option that provides a 32-bit virtual channel frame count by combining:
  • a 4‑octet (32‑bit) Secondary Header length (value 3),
  • a 24‑bit extension in the Secondary Header data field, and
  • the 8‑bit Virtual Channel Frame Count in the Primary Header.
  • The extended count must be associated either with a master channel or a virtual channel and remain static through a mission phase.
• Service interfaces and protocol procedures: CCSDS formalizes abstract service interfaces (service primitives) and sender/receiver procedures; this Adoption Notice preserves those interfaces for ECSS use.
• Space Data Link Security (SDLS) interfaces: The adoption includes optional interfaces to use SDLS with TM Transfer Frames - an option not present in the earlier ECSS document.
• Operational clarifications: Annex A highlights differences such as managed parameters, synchronization-flag handling, and frame-count reset policy wording compared with the superseded ECSS text.

Applications - who uses this standard

• Spacecraft systems and communications engineers designing telemetry links
• Satellite prime contractors and payload integrators implementing TM framing
• Ground-segment and mission-operations teams handling telemetry processing and channel management
• Test and verification teams ensuring ECSS-compliant data-link behavior
• Standards and compliance officers integrating CCSDS protocols into ECSS-based projects

Related standards

• EN 16603-50-23 (AOS Space Data Link Protocol)
• EN 16603-50-21, -24, -25, -26 (other ECSS adoptions of CCSDS data-link, TC and sync/coding documents)
• CCSDS 132.0-B-2 (original TM Space Data Link Protocol)

This Adoption Notice ensures interoperability between CCSDS TM framing and ECSS practice, enabling robust telemetry transfer, optional security integration (SDLS), and consistent mission-level channel management.
