This International Standard specifies the requirements for the services and protocols of the space communications protocol specification (SCPS) transport service. These requirements are meant to allow independent implementations of this protocol in space and ground segments of the SCPS network to interoperate.

This International Standard is applicable to any kind of space mission or infrastructure, regardless of complexity.

The scope and field of application are further detailed in subclauses 1.2 and 1.3 of the enclosed CCSDS publication.
