Full title and description

ISO 17807:2013 — Space data and information transfer systems — Asynchronous message service. This International Standard defines a CCSDS Asynchronous Message Service (AMS) for mission data system communications: a protocol and service framework enabling autonomous modules of flight and ground data systems to exchange mission information asynchronously, with automatic configuration and dynamic reconfiguration of communication relationships.

Abstract

ISO 17807:2013 specifies the AMS service model, protocol procedures and protocol data units (PDUs) that enable self-configuring, asynchronous message exchange among mission data system modules. The standard describes how AMS supports modular, loosely coupled architectures for spacecraft and ground systems, allowing modules to produce and consume information without hardwired knowledge of other modules’ presence or state. The goal is to reduce mission cost and operational risk by providing a reusable, scalable, robust messaging infrastructure suitable for intra‑spacecraft, space‑to‑ground, ground‑to‑ground and interplanetary message exchanges.

Scope

ISO 17807:2013 applies to the definition and specification of an Asynchronous Message Service (AMS) and its protocol suite for mission data systems. It covers AMS service descriptions, protocol specification, protocol data units, user operations, conformance classes and management information elements. The standard is intended for use between modules within a ground data system, within a flight data system, between flight and ground modules, and between systems across agencies and spacecraft — including use over long (interplanetary) distances and across diverse transport continua.

Key topics and requirements

• Concept and architecture of the CCSDS Asynchronous Message Service (AMS).
• Service descriptions and user operations for asynchronous message exchange.
• Detailed protocol specification and definition of protocol data units (PDUs).
• Automatic discovery/automatic configuration of communication relationships among modules.
• Dynamic reconfiguration of relationships during operations (robustness and fault tolerance).
• Conformance classes and protocol implementation conformance statements.
• Management information base and operational management considerations.
• Recognized transport services and guidance for mapping AMS to underlying transports.
• Security considerations (informative annex) and reserved parameter values.

Typical use and users

Primary users are spacecraft systems engineers, mission data system architects, flight and ground software developers, ground-segment integrators, space agency standards and interoperability teams, and contractors implementing CCSDS-based messaging for spacecraft operations, telemetry/telecommand support, distributed onboard software modules, and inter-agency data exchange.

Related standards

ISO 17807:2013 is part of the family of space data and information transfer standards and relates to CCSDS recommended standards and several ISO publications addressing space communications and mission services. Relevant related documents include CCSDS AMS publications and other ISO/CCSDS standards such as ISO 17355 (CCSDS File Delivery Protocol / CFDP), ISO 17107 (XML specification for navigation data messages) and CCSDS Mission Operations and related service specifications. Implementers typically consider AMS together with transport and delay-tolerant networking protocols (e.g., DTN/Bundle Protocol) and other CCSDS messaging/file-transfer standards.

FAQ

Q: What is this standard?

A: ISO 17807:2013 specifies the CCSDS Asynchronous Message Service (AMS) — a protocol and service framework for asynchronous message exchange among mission data system modules in spacecraft and ground systems.

Q: What does it cover?

A: It covers AMS service descriptions, protocol procedures, protocol data units, user operations, conformance classes, management information, recognized transport services and informative guidance (including security considerations and conformance proformas).

Q: Who typically uses it?

A: Spacecraft and ground system architects, flight and ground software developers, mission operations engineers, interoperability teams at space agencies, and contractors implementing CCSDS messaging for missions across agencies or long distances.

Q: Is it current or superseded?

A: ISO 17807 was published in June 2013 (Edition 1). The publication was confirmed during ISO’s systematic review process (most recently confirmed in 2018). As with all ISO standards it is subject to periodic review; users should verify the current status with the standards body before relying on the document for procurement or certification.

Q: Is it part of a series?

A: It is part of the ISO/CCSDS space data and information transfer family of standards and complements other CCSDS and ISO standards that address file delivery (CFDP), mission operations services, transport mappings and related space communications protocols.

Q: What are the key keywords?

A: Asynchronous Message Service, AMS, CCSDS, mission data system, protocol data unit, dynamic reconfiguration, automatic configuration, space communications.
