HORST

Description

HORST is the main management software entity on the MOVE-II board computer.

HORST is responsible for keeping the satellite in a safe state by reacting on critical events like low battery or high temperatures with appropriate actions.

HORST listens on state signals of other daemons on D-Bus and stores the current state in his internal memory and thereby gains a global view on the state of the satellite, which allows a check of cross-subsystem dependencies. Based on this global state view HORST can decide to react on defined conditions with also predefined actions. A logic state table is processed on each incoming state update event what might invoke actions. These actions are provided as shell scripts.

Besides the D-Bus interface for satellite local commanding HORST also implements an S3TP interface for executing arbitrary shell commands on the satellite.
