Full title and description

ISO 23104:2020 — Space link extension — Cross support transfer service — Monitored data service. This Recommended Standard defines the Monitored Data service (MD‑CSTS) as an extension to the Cross Support Transfer Services framework, specifying the procedures, behavioural refinements and operation‑level extensions required to exchange monitored parameter reports, on‑demand queries and event notifications between cross‑support ground complexes and mission users.

Abstract

The document describes the Monitored Data service in terms of: the CSTS procedures that make up the service; extensions and refinements of CSTS behaviour needed to provide monitored‑data transfer; operation‑level extensions associated with each procedure; and the relationships among those procedures. It explicitly does not prescribe specific implementations, measurement technologies, communication technologies or particular parameter lists to report.

Scope

ISO 23104:2020 defines the Monitored Data service (MD‑CSTS) as a Cross Support Transfer Service enabling cyclic reporting, on‑demand queries and event notifications of parameters relevant to cross‑support services provided by a Cross Support Complex (Earth Space Link Terminal). The scope is limited to specifying service behaviour and interfaces at the CSTS level; it excludes prescriptions of product implementations, interface internals, methods for sensing/measuring parameters, communication protocols beyond the CSTS abstractions, and the choice of which parameters or events shall be monitored for any particular mission.

Key topics and requirements

• Definition of the Monitored Data service (MD‑CSTS) and its role within the CSTS framework.
• Detailed CSTS procedures that constitute the monitored‑data service (cyclic reports, queries, notifications).
• Behavioral extensions and refinements of standard CSTS operations to support monitored data transfer.
• Operation‑level extensions associated with each procedure and relationships among procedures.
• Interoperability focus — standardizing service behaviour rather than mandating implementations or measurement techniques.
• Constraints: the standard does not specify particular measurement technologies, parameter lists, or low‑level communication implementations.

Typical use and users

Primary users include space agencies, mission operations teams, ground‑segment designers and integrators, telemetry/telecommand and ground‑station vendors, and systems engineers responsible for cross‑support interfaces and multi‑agency interoperability. The standard is used as a reference for specifying monitored‑data exchanges, procuring CSTS‑compliant equipment and for integration testing of cross‑support ground complexes.

Related standards

ISO 23104:2020 is part of the ISO/TC 20/SC 13 area (space data and information transfer systems) and is aligned with Cross Support Transfer Services (CSTS) concepts originating in CCSDS recommendations. Implementers commonly use ISO 23104 together with other space‑data transfer and ground‑segment standards and CCSDS technical recommendations that define CSTS architecture and interfaces.

FAQ

Q: What is this standard?

A: ISO 23104:2020 specifies the Monitored Data service as a Cross Support Transfer Service (MD‑CSTS) for exchanging monitored parameter reports, queries and event notifications between cross‑support complexes and mission users.

Q: What does it cover?

A: It covers the CSTS procedures, behavioural refinements and operation‑level extensions required to deliver monitored‑data transfer; it does not cover specific product implementations, sensing methods, or low‑level communication technologies.

Q: Who typically uses it?

A: Space agencies, mission operations teams, ground‑segment designers and integrators, spacecraft/ground equipment vendors, and systems engineers working on cross‑support interoperability.

Q: Is it current or superseded?

A: As published on 31 January 2020 (Edition 1), ISO records show the standard as published/confirmed. Users should check the ISO catalogue or their national standards body for any revisions or confirmations after publication if they need the absolute latest lifecycle status.

Q: Is it part of a series?

A: It sits within the space data/ground‑segment standards area (ISO/TC 20/SC 13) and references the broader CSTS/CCSDS work on cross‑support transfer services; implementers typically consider it alongside related CCSDS and ISO space‑data transfer documents.

Q: What are the key keywords?

A: Monitored Data, MD‑CSTS, Cross Support Transfer Service, CSTS, space link extension, telemetry, event notification, ground segment interoperability.
