What is car navigation?
Car navigation is generally a satellite navigation system that typically uses a GPS navigation device to acquire position data and locate it in the device's map database. The system can then can give directions to other locations along roads also in its database.
Dead reckoning using distance data from sensors attached to the drive-train, a gyroscope and an accelerometer can be used to increase reliability when there is loss of GPS signal and/or multi-path in urban canyons, tunnels and underground parking lots. Most sensors used for this are usually already present in high-end cars for other purposes like anti-lock braking system, electronic stability control, etc.
