Full title and description

Space data and information transfer systems — Proximity-1 space link protocol — Data link layer. This International Standard specifies the Data Link Layer for the Proximity‑1 space link protocol, including framing, medium access control, protocol data units, data services and I/O sublayers used to establish and manage communications between proximate space platforms (e.g., lander-to-orbiter links).

Abstract

ISO 22663:2015 defines the Data Link Layer (framing, medium access control, data services and input/output sublayers). It specifies protocol data units, framing, media access control, expedited and sequenced-controlled data transfer, timing services, I/O control, and the procedures for establishing and terminating a session between a caller and responder. Coding/synchronization and physical-layer details are defined in companion CCSDS/Proximity‑1 documents.

Scope

This standard specifies the Data Link Layer services and protocol elements required to support reliable short‑range space links under the Proximity‑1 family. It covers framing formats and rules, PDU structures, medium access control (including negotiation of data rate and modes), expedited and sequenced transfer mechanisms, timing and synchronization services at the data‑link level, I/O control primitives and the procedures to establish, maintain and terminate sessions between caller and responder entities. The standard does not prescribe physical implementation technologies; coding/synchronization and physical‑layer functions are addressed in the companion CCSDS Proximity‑1 Blue Books.

Key topics and requirements

• Definition of Proximity‑1 Data Link Layer sublayers: Framing, MAC, Data Services, I/O.
• Protocol Data Unit (PDU) formats and versioning (including version‑3 transfer frame context).
• Framing rules and synchronization requirements for reliable delivery over short‑haul space links.
• Medium Access Control procedures for negotiated data rates and access modes between proximate platforms.
• Expedited and sequenced‑controlled data transfer services and error handling.
• Timing and session management services: session establishment, control and termination procedures.
• Interoperability and alignment with CCSDS Proximity‑1 Coding & Synchronization and Physical Layer recommendations (companion documents).

Typical use and users

Intended users are spacecraft communication system designers, mission systems engineers, payload and spacecraft integrators, mission planners and ground segment engineers implementing or operating proximity links (for example lander‑to‑orbiter relays and short‑range inter‑vehicle communications). It is used when ensuring interoperable, mission‑level data transfer services for proximate space platforms and when deriving implementation requirements from Proximity‑1 protocol behaviors.

Related standards

Primary related documents are the CCSDS Proximity‑1 Blue Books, notably the Proximity‑1 Coding and Synchronization Sublayer and the Proximity‑1 Physical Layer (CCSDS Proximity‑1 recommendations such as CCSDS 211.0 series). ISO 22663:2015 supersedes ISO 22663:2007 (previous edition) and is produced under ISO/TC 20/SC 13 (Space data and information transfer systems).

FAQ

Q: What is this standard?

A: ISO 22663:2015 is the International Standard that defines the Data Link Layer for the Proximity‑1 space link protocol used for short‑range space communications (e.g., lander-to-orbiter links).

Q: What does it cover?

A: It covers framing formats, protocol data units, medium access control, expedited and sequenced-controlled data transfer, timing services, I/O control, and session establishment/termination procedures at the Data Link Layer. Coding/synchronization and physical‑layer aspects are described in companion CCSDS documents.

Q: Who typically uses it?

A: Spacecraft comms engineers, mission designers, ground segment and operations teams, and anyone implementing or verifying Proximity‑1 compliant data‑link functionality for proximity links.

Q: Is it current or superseded?

A: ISO 22663:2015 is the 3rd edition (published August 2015) and replaced the 2007 edition. The ISO bibliographic record indicates the publication is confirmed and subject to periodic review per ISO procedures. Users should check their national bodies or ISO for any later revisions or confirmations.

Q: Is it part of a series?

A: Yes — it is part of the Proximity‑1 family of documents (the Data Link Layer standard is complemented by Proximity‑1 Coding & Synchronization and Proximity‑1 Physical Layer CCSDS recommendations). The Proximity‑1 Blue Books from CCSDS provide the companion lower‑layer and coding details.
