ISO DIS 18439

Description / Abstract: This International Standard defines a set of Space Communication Cross Support Service Management (SCCS-SM) services by which space link service providers and space missions exchange information needed to arrange spacecraft contact periods and establish the operating parameters of the space link services and cross support transfer services during those contact periods. It deals with only three of the SLE transfer services defined in the Cross Support Reference Model:

a) Forward Communications Link Transmission Unit (FCLTU, reference [11]);

b) Return All Frames (RAF, reference [8]);

c) Return Channel Frames (RCF, reference [9]).

This International Standard is applicable to space communication service management systems that are involved in cross support.

The scope and field of application are furthermore detailed in subclauses 1.4 (and 1.5) of the enclosed CCSDS publication.
