Mission DatabaseΒΆ

The Mission Database describes the telemetry and commands that are processed by Yamcs. It tells Yamcs how to decode packets or how to encode telecommands.

The database organizes TM/TC definitions by space system. A space system may contain other sub-space systems, thereby structuring the definitions in logical groups. Space systems have a name and can be uniquely identified via UNIX-like paths starting from the root of the space system hierarchy. For example: /BogusSAT/SC001/BusElectronics could be the name of a sub-space system under /BogusSAT/SC001. The root space system is /.

The terminology used in the Yamcs Mission Database is very close to the terminology used in the XTCE exchange format. XTCE prescribes a useful set of building blocks: space systems, containers, parameters, commands, algorithms, etc.
