Description / Abstract: ISO 18424:2013 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 ISO 18424:2013 is limited to the satellite telemetry and commanding meta-data constructs necessary to perform satellite and payload data processing. ISO 18424:2013 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 ISO 18424:2013 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. ISO 18424:2013 addresses only the definition of TM/TC data, but is not a specification for the transfer of live or historical TM/TC data. It is a meta-data specification, not a data specification.
