AOS data links: Recommendations and standards

The Consultative Committee for Space Data Systems (CCSDS) publishes recommendations documents for the AOS (Advanced Orbiting Systems) space data link for telemetry and telecommand. The recommendations define protocols, procedures and data structures, including the AOS Transfer Frame.

The documents can be downloaded from the CCSDS site at www.ccsds.org.

Note: The AOS recommendations define the AOS Space Data Link Protocol for handling Version-2 Transfer Frames, known as AOS Transfer Frames. The packet telemetry recommendations define the TM Space Data Link Protocol for handling Version-1 Transfer Frames, known as TM Transfer Frames.

CCSDS original recommendations for AOS data links

The CCSDS original recommendations for AOS are now obsolete (silver status):

Advanced Orbiting Systems, Networks and Data Links, CCSDS 701.0-B-3-S, June 2001

The original recommendations have some differences, for example in presentation and technical terms, but the major technical content is similar to the current recommendations.

ESA Standards and ECSS

ESA and ECSS do not currently publish standards for AOS telemetry/telecommand.
