ISO 22642:2005 (CCSDS 231.0-B-1:2003)
Space data and information transfer systems -- TC (telecommand) synchronization and channel coding
This standard has been revised by ISO 22642:2015.
ISO 22642:2005 defines synchronization and channel coding schemes used with the telecommand (TC) space data link protocol as defined in ISO 22664. These schemes are to be used over ground-to-space or space-to-space communications links by space missions.
