retroactive, nor does it commit any Agency to implement the recommended telecommand
concepts at any future time. Nevertheless, all CCSDS Agencies accept the principle that all
future implementations of telecommand which are used in cross-support situations will be
based on this Recommendation.
The CCSDS has developed a layered concept for spacecraft telecommanding, which is fully
described in Reference [C2]. Standard services are defined within each layer, and Agencies
will be encouraged to develop corresponding facilities to provide these services in support of
Projects. To be fully compatible with the CCSDS concept, a Project’s telecommanding
architecture should follow this Recommendation for Channel Service, plus the
Recommendations for telecommand “Data Management Service” and telecommand “Data
Routing Service” which are described in References  and , respectively. Projects may
also elect to be partially compatible with the concept by interfacing with the standard systems
