Safety Information Module (SIM): Notes
In the network of satellites, the Safety Information Module SIM is the central unit. The SIM has the following functions:
- Supply operating power to the satellites and provide an energy reserve in the event of failure of the voltage supply during an accident.
- The SIM is the connection master (using the Intelligent Star Coupler) and system master of the byteflight fiber-optic network.

The SIM is located behind the glovebox.
