- The complexity of the hardware must be proportionate to the needs of the system, without unnecessary redundancies in order to maximize its reliability (no PLC nor PC)
- Each unit of the system (single fin control, stabilization control, command and monitoring stations) must have its own operational autonomy so as to be able to intervene automatically in case of failure of one of the other units, and operate in degraded system condition or secure the system (housing fins).
