Full title and description

ISO 22664:2016 — Space data and information transfer systems — TC (telecommand) space data link protocol. This International Standard defines the telecommand (TC) space data link protocol, including the services provided to users, the protocol data units (PDUs) used and the procedures to be performed by the protocol; it does not prescribe specific implementations, technologies or management/operational activities for product deployment.

Abstract

ISO 22664:2016 specifies the TC Space Data Link Protocol in terms of: (a) services provided to protocol users; (b) protocol data units employed by the protocol; and (c) the procedures performed by the protocol. The standard explicitly excludes requirements for individual implementations, service-interface implementation within real systems, methods/technologies to perform procedures, and protocol configuration/management activities.

Scope

ISO 22664:2016 defines the telecommand (TC) space data link protocol used for sending commands to spacecraft and associated ground/space segments. It covers the protocol services available to users, the structure and semantics of protocol data units, and the procedures required to operate the protocol. It does not mandate hardware or software implementations, nor the internal design of systems that implement the protocol.

Key topics and requirements

• Definition of services provided by the TC data link protocol (service primitives and behaviors for telecommand delivery).
• Specification of protocol data units (PDU formats, fields and semantics) used for telecommand transfer.
• Procedures and state machines governing transmission, acknowledgement, error handling and sequencing of telecommands.
• Managed parameters and option sets (including provisions covering SDLS-related options in draft/implementation materials).
• Interoperability considerations with related space communications frameworks (references and cross-links to CCSDS and other space communications documents are common in implementations).

Typical use and users

Primary users include spacecraft system architects, mission operations engineers, satellite manufacturers, ground-segment integrators and organizations responsible for command and control of space systems. The standard is applied when specifying or implementing telecommand data links to ensure consistent, interoperable behaviour between space and ground elements. Industry and national standards bodies (and vendors supplying space communications equipment) rely on the standard during system design, procurement and verification.

Related standards

ISO 22664:2016 is the third edition in the ISO 22664 series and follows earlier editions/amendments (ISO 22664:2013 and ISO 22664:2013/Amd 1:2015). Implementers commonly cross-reference CCSDS (Consultative Committee for Space Data Systems) recommendations and other space communications standards and OSI service definitions when integrating telecommand data link functionality. For implementation-specific guidance and normative references, see the standard’s informative annexes and referenced documents.

FAQ

Q: What is this standard?

A: ISO 22664:2016 is an International Standard that defines the TC (telecommand) space data link protocol — the protocol layer and services used to deliver telecommands between ground and space elements.

Q: What does it cover?

A: It covers the services provided to users of the protocol, the protocol data units (PDU) and their structure, and the procedures required to operate the protocol (transmission, acknowledgement, error handling, sequencing). It does not specify hardware, software implementations, internal service-interface implementations, or management activities for configuration/control.

Q: Who typically uses it?

A: Spacecraft manufacturers, mission and ground segment engineers, satellite operators, systems integrators, and standards bodies use ISO 22664 when designing, specifying or validating telecommand data links.

Q: Is it current or superseded?

A: ISO 22664:2016 is published and — according to ISO’s catalogue lifecycle — was reviewed and confirmed as the current edition in 2023. It supersedes earlier editions (2013 and its 2015 amendment).

Q: Is it part of a series?

A: Yes. ISO 22664 is a numbered ISO standard with previous editions and amendments (e.g., 2013 edition and 2013/Amd 1:2015). It is typically used alongside other space data/communications standards and CCSDS recommendations for complete mission communications architectures.

Q: What are the key keywords?

A: Space data link, telecommand, PDU, protocol services, SDLS, spacecraft command and control, space communications.
