The satellite sensors connected to the ACU consist of pressure and acceleration sensors and ensure the detection of the different crash scenarios. An external IMU can be provided additionally if required.
 
pSAT pressure satellites were developed specifically for side crashes. They are installed in the cavity of the door and rapidly detect the change of pressure within the door, thereby reacting extremely quickly.
 
The acceleration satellite sensors (g-sat) measure and supply the information on the acceleration values in the rigid vehicle structures to the airbag control unit. The airbag control unit can determine both – the duration of intrusion and the intensity of the crash – and activate lifesaving restraint systems in just milliseconds.
 
The components offer excellent quality (close to 0 ppm) and are based on extensive worldwide field experience.
