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 includesthe 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.
