Full title and description

Space data and information transfer systems — Communications operation procedure‑1 (COP‑1). This International Standard defines the COP‑1 protocol used with the telecommand (TC) space data link protocol to ensure correct, in‑order, non‑duplicated delivery of service data units between protocol layers in spacecraft communications systems.

Abstract

ISO 22667:2013 specifies the communications operation procedure‑1 (COP‑1). It defines the procedure's interfaces with other procedures, the internal variables used by the protocol entity, the actions performed by the protocol entity, and the state transitions of the protocol entity. The standard does not specify particular implementations, service interface implementations within real systems, the methods or technologies required to perform the procedures, nor management activities required to configure and control the protocol.

Scope

This standard specifies COP‑1 (Communications Operation Procedure‑1) to be used with the telecommand (TC) space data link protocol (as defined in ISO 22664:2013). Its scope covers the interface definitions, internal protocol variables, protocol actions and state transitions required to deliver service data units correctly, without omission or duplication, and in the correct sequence between adjacent protocol layers. It explicitly excludes prescription of specific implementations, product designs, or management/configuration methods.

Key topics and requirements

• Definition of COP‑1 protocol behaviour (interfaces, actions, state machine).
• Mechanisms to ensure in‑order, complete, non‑duplicated delivery of service data units.
• Specification of internal protocol variables and their allowable transitions.
• Interface requirements with related space data link procedures (e.g., telecommand data link).
• Statement of what the standard does not cover—implementation details, management procedures, and specific technologies.

Typical use and users

ISO 22667:2013 is used by spacecraft communications engineers, protocol designers, avionics and satellite system integrators, ground segment developers, space agencies, and contractors implementing telecommand and telemetry data‑link stacks. It is applied when designing or validating protocol implementations that must interoperate with other COP/TC protocol implementations and with CCSDS‑aligned systems.

Related standards

Key related documents include ISO 22664 (telecommand space data link protocol) and earlier or companion ISO/CCSDS documents addressing space data and information transfer system services and operations; ISO 22667:2005 is the previous edition. Implementers often cross‑reference CCSDS protocol recommendations and related ISO space systems standards when building interoperable spacecraft communications stacks.

FAQ

Q: What is this standard?

A: ISO 22667:2013 defines the Communications Operation Procedure‑1 (COP‑1) used in space data and information transfer systems to provide correct, in‑order delivery of service data units for telecommand applications.

Q: What does it cover?

A: It covers the COP‑1 protocol's interfaces, internal variables, actions, and state transitions; and it describes expected behaviour to ensure delivery without omission, duplication, and in sequence. It does not prescribe specific product implementations or management/configuration techniques.

Q: Who typically uses it?

A: Spacecraft communications engineers, system integrators, space agencies, and vendors implementing telecommand/data‑link protocol layers and aiming for CCSDS/ISO interoperability.

Q: Is it current or superseded?

A: The 2013 edition (ISO 22667:2013, Edition 2) is the current published edition, having replaced ISO 22667:2005. Users should check the ISO catalogue or national standards body for any later reviews or updates.

Q: Is it part of a series?

A: Yes. ISO 22667 is part of a set of standards addressing space data and information transfer systems and is used together with related standards such as ISO 22664 (telecommand data link protocol) and CCSDS recommendations for interoperable space communications.
