Full title and description

St ISO 23103-2020 — "Space link extension — Cross support transfer service — Specification framework". This international standard defines an abstract specification framework for Cross Support Transfer Services (CSTS) used to transfer spaceflight mission–related data between ground elements and user elements, describing procedures, states, behaviors, operations and parameters for such services while deliberately not prescribing specific implementations or technologies.

Abstract

ISO 23103:2020 provides a Recommended Standard that defines, in an abstract manner, a CSTS in terms of: the procedures necessary to provide the service; the states of the service and of each procedure; the behaviour of each procedure; the operations that make up procedures; and the parameters associated with operations. It explicitly does not specify individual application services, implementations or products, nor the specific methods or technologies for data acquisition, communications environment or operational management.

Scope

The standard provides a framework for Cross Support Transfer Services (CSTS) as part of the space link extension family: it defines the abstract procedures, states, operations and parameters required to describe and specify transfer services for different types of mission-related data (for example telemetry, tracking or monitored data). It is intended to support interoperability between ground systems and control centres but does not mandate concrete implementations, specific communication technologies, or management processes for scheduling and configuration.

Key topics and requirements

• Definition of the CSTS conceptual framework: procedures, procedure states and service states.
• Specification of behaviour for each procedure and the operations that constitute procedures.
• Parameter definitions associated with CSTS operations and procedures.
• Abstraction to enable different CSTS types (e.g., telemetry transfer, tracking data, monitored data) to be built on a common framework.
• Interoperability focus — framework intended to enable cross-support data transfers between heterogeneous ground systems and agencies.
• Explicit non-prescriptive scope: the standard does not define implementations, technologies for data acquisition, communications channel specifics, nor scheduling/management procedures.

Typical use and users

Primary users are space agencies, ground-station operators, mission control centres, systems and software engineers working on ground segment interoperability, and vendors of ground-station and mission-support systems. The framework is used when designing or specifying cross-support data transfer services to ensure consistent behaviour and interoperability across different organisations and implementations.

Related standards

ISO 23103 is part of a family of space link extension and cross-support standards. Closely related documents include ISO 23104:2020 (Space link extension — Cross support transfer service — Monitored data service) and other ISO/TC 20/SC 13 outputs addressing space data and information transfer systems; it also aligns conceptually with CCSDS work on cross-support transfer services and related CCSDS libraries and recommended practices.

FAQ

Q: What is this standard?

A: ISO 23103:2020 is an international standard titled "Space link extension — Cross support transfer service — Specification framework" that defines an abstract framework for Cross Support Transfer Services (CSTS) used to transfer mission-related data between ground elements and users.

Q: What does it cover?

A: It covers the abstract definition of CSTS procedures, the states and behaviour of services and procedures, the operations that make up procedures, and the parameters for those operations. It does not define specific implementations, hardware, communication technologies, or operational management processes.

Q: Who typically uses it?

A: Space agencies, ground-station and mission support system designers, systems engineers, and vendors who need to specify or implement interoperable cross-support data transfer services.

Q: Is it current or superseded?

A: ISO 23103:2020 was published in January 2020 (Edition 1). According to ISO’s lifecycle information the standard is published and subject to the normal 5‑year review cycle for ISO standards; users should check the ISO catalogue or national standards body for any confirmations, amendments or subsequent revisions after 2020.

Q: Is it part of a series?

A: Yes — it is part of the space link extension / cross-support family of documents produced under ISO/TC 20/SC 13. Companion documents (for example ISO 23104:2020 for the Monitored Data service) define specific CSTS types and extensions built on the framework.

Q: What are the key keywords?

A: CSTS, Cross Support Transfer Service, space link extension, interoperability, ground station, telemetry, tracking, monitored data, ISO 23103, space systems.
