Gyro Sensors in Car Navigation

Car navigation systems are often unable to receive GPS satellite signals when the vehicle is in a tunnel, indoor parking garage, traveling between tall buildings, or in similar environments. In situations like these, a process called dead reckoning is used to augment GPS position data. In dead reckoning the gyro sensor outputs an angular rate; that is, the degrees of rotation per second. The system has to then calculate the angle based on this data. Even if a GPS signal cannot be received, the gyro sensor tracks how far right and left the vehicle turns, while vehicle speed pulse signals provide information on distance traveled. The direction and speed data are compared with map data to infer vehicle position.
