Door Satellites (STVL/STVR)

The Door Satellites (STVL/STVR) are located in the left/right passenger doors.

The door satellites are connected to the SIM via the byteflight. Power supply for the door satellites is also provided by the SIM and is buffered by the memory backup capacitor.

A pressure sensor, which constantly monitors the pressure in the door, is integrated into each door satellite. Pressure changes in the door that occur during penetration of the outer door skin are evaluated and passed on through the SIM for airbag deployment activation.
