Dead Reckoning (gyroscope)
The current position can be established momentarily, for driving through a tunnel, for
example, with the aid of this function, even without a valid GPS signal.
The navigation system will receive the necessary information during the absence of the
GPS signal for a short time, to continue to establish the position through an installed mag-
netic field and acceleration sensor.
The methods for establishing the position by means of the sensor described represents
merely one device, so that deviations can arise. Sufficient GPS reception must be available
before the transfer to establishment of the position by means of dead reckoning because of
the system.
Dead reckoning is not a complete replacement for GPS-supported navigation.
