This International Standard addresses the need for a standardized information model capable of supporting Telemetry/Telecommand (TM/TC) definitions across the widest possible range of space domain activities. The goal is to allow TM/TC definitions to be exchanged between different organizations and systems, often at the boundaries of mission phases, without the need for customized import/export, re-validation, or even re- implementation of mission databases. The scope of this International Standard is limited to the satellite telemetry and commanding meta-data constructs necessary to perform satellite and payload data processing. This International Standard includes the meta-data needed to: - Define the structure and sequence of both CCSDS packets and TDM frames; - Define the data manipulation required for packaging and unpacking of individual data items; - Describe command data including command identification, argument specification, and validation criteria; - Define parameter and command encoding; - Define data properties including including default values, validity criteria, and data dependencies. The scope of this International Standard does not extend to: - Data distribution mechanisms or rules; ? Command and data protocol specifications; ? RF or analog stream characterization; - Data grouping including aggregation and coherent data sets; ? Data representation (visualization properties); - Scheduling configuration properties; - Orbital properties; - Displays; - Flight Software. This International Standard addresses only the definition of TM/TC data, but is not a specification for the transfer of live or historical TM/TC data - this is a meta-data specification, not a data specification.
