2. Direction sensor
Although the GPS antenna allows the detection of the vehicle’s position on a map, it cannot determine the vehicle’s direction of travel. Car navigation systems use a direction sensor (gyro-sensor) to determine the vehicle’s orientation and direction of rotation. The direction sensor (gyro-sensor) contains an oscillating element and calculates the vehicle’s direction of rotation and orientation by detecting changes in the element’s oscillation triggered by changes in the vehicle’s orientation. The car navigation system displays the vehicle’s orientation on its screen based on the signal from this direction sensor (gyro-sensor).
As an example, the Coriolis force is the force that causes you to walk along a curved path when you try to close your eyes and walk in a straight line from the center (outer edge) of a merry-go-round to its outer edge (center).
