Full title and description

ISO 21076:2016 — Space data and information transfer systems — Space communications cross support — Architecture requirements document. This International Standard defines an architecture and normative requirements for Space Communications Cross Support (SCCS), covering key elements on ground and in space, service concepts, secure service requirements, recommended protocol stacks, and end-to-end configurations to enable interoperable cross-supportable space communications services.

Abstract

ISO 21076:2016 describes SCCS architecture by: defining key space and ground elements involved in space communications; defining concepts that characterize SCCS services; specifying requirements on elements and components to provide secure SCCS services; recommending protocol-stack configurations for element types; and recommending end-to-end system configurations to support interoperable and cross-supportable services. The document also clarifies what it does not specify (implementation details, explicit technologies, most mission operations protocols, etc.).

General information

• Status: Published (confirmed in ISO five‑year review, remains current).
• Publication date: July 2016 (Edition 1, 2016‑07).

Scope

The standard covers architecture and requirements for Space Communications Cross Support for both single‑hop Data Link Layer services and multi‑hop Solar System Internet (SSI) Network Layer services. It addresses agency‑to‑agency interoperable services (ground and space elements), recommended protocol stacks, and transition strategies from present deployments to an SSI‑capable infrastructure. It explicitly excludes low‑level implementation details, prescriptions of specific technologies, and most mission operations protocols outside of data transfer.

Key topics and requirements

• Definitions of key SCCS elements (Earth and space nodes, routing/relay nodes, service elements).
• Concepts characterizing SCCS services (ABA single‑agency cross support and SSI multi‑agency internetworking).
• Security and operational requirements for system elements and components providing SCCS services.
• Recommended protocol stack configurations for element types (link, network, and transport considerations).
• Recommended end‑to‑end system configurations for interoperable single‑hop and SSI deployments and transition strategies between them.
• Guidance on service management, planning/scheduling interfaces, and roles of service provider and user nodes.
• Reference to CCSDS technical recommendations and relevant OSI layering principles for protocol selection and mapping.

Typical use and users

Used by space agencies, mission and network architects, ground station operators, spacecraft communication systems engineers, standards bodies and vendors developing interoperable cross‑support communications infrastructure. It is a design and procurement reference when planning multi‑agency missions, interagency ground‑station services, or evolutionary migration toward SSI capabilities.

Related standards

ISO 21076:2016 is aligned with and references CCSDS architecture and engineering recommendations (for example CCSDS 901.1‑M‑1 Space Communications Cross Support — Architecture Requirements) and other CCSDS/ISO documents addressing space link extension, internetworking, and file/transfer protocols (CFDP, BP, LTP, etc.). It is intended to be used alongside CCSDS recommended practices and companion architecture description documents.
