Full title and description

ISO 22666:2016 — Space data and information transfer systems — AOS (Advanced Orbiting Systems) space data link protocol. This International Standard defines the AOS data link protocol: the services provided to users, the protocol data units (PDUs) used and the procedural behaviour of the protocol for space‑to‑ground, ground‑to‑space and space‑to‑space communications.

Abstract

ISO 22666:2016 specifies the AOS Space Data Link Protocol at the data‑link layer (as referenced to the OSI model). The document describes the services offered to user entities, the structure and semantics of protocol data units, and the procedures required to support those services. It intentionally does not mandate specific implementations, hardware, software architectures or management procedures.

Scope

Applies to the definition and formal specification of the AOS data link protocol to be used by space missions for transfer of telemetry, telecommand and mission data across space communications links (space‑to‑ground, ground‑to‑space and space‑to‑space). The standard covers services, PDU formats and protocol procedures but excludes implementation‑level design, specific product requirements, and network management/configuration methods.

Key topics and requirements

• Definition of AOS services available to user entities (service primitives and semantics).
• Specification of protocol data units (PDU) structures and fields used by AOS.
• Procedural rules for transmission, reception, segmentation/reassembly and error handling at the AOS data link layer.
• Usage scenarios over space‑to‑ground, ground‑to‑space and space‑to‑space links.
• Interoperability considerations with higher OSI layers and other space data link standards (protocol boundary behaviour, addressing and service access points).
• Statements of what the standard does not mandate (no implementation, product or management prescriptions).

Typical use and users

Engineers and architects designing space communications subsystems, spacecraft and ground‑station software/hardware developers, mission systems integrators, avionics and satellite communications teams, and standards bodies working on space data transfer interoperability. Also used by test laboratories and procurement/specification writers when defining data‑link behaviour and conformance for space missions.

Related standards

ISO 22666:2016 is part of the family of space data and information transfer standards maintained by ISO/TC 20/SC 13 and relates to previous editions and amendments (ISO 22666:2005, ISO 22666:2007 and ISO 22666:2007/Amd 1:2015). It is complementary to OSI‑layer references such as ISO/IEC 7498‑1 and to CCSDS (Consultative Committee for Space Data Systems) recommendations addressing space data link and packetization practices.

FAQ

Q: What is this standard?

A: ISO 22666:2016 is an International Standard that specifies the AOS (Advanced Orbiting Systems) space data link protocol used for transferring mission data over space communications links.

Q: What does it cover?

A: It covers the services provided by the AOS protocol, the formats and semantics of protocol data units (PDUs), and the procedures the protocol uses (e.g., segmentation/reassembly, transfer and error handling). It does not prescribe implementations, hardware designs or management methods.

Q: Who typically uses it?

A: Spacecraft communications engineers, ground segment developers, mission integrators, test houses, and standards/requirements authors who need a formal data‑link specification for space missions.

Q: Is it current or superseded?

A: The edition published on 3 November 2016 (Edition 3) is the current published edition; the ISO metadata shows this edition as published and confirmed during routine review. Users should check ISO or their national standards body for any later revisions or amendments.

Q: Is it part of a series?

A: Yes — it is part of ISO work for space data and information transfer systems (ISO/TC 20/SC 13) and is related to earlier ISO 22666 editions and to other space communications standards and CCSDS recommendations.

Q: What are the key keywords?

A: AOS, space data link, data link layer, PDUs, telemetry, telecommand, space communications, interoperability.
