With a self-contained navigation system, calculation of the actual position of the car is based on the principle of dead reckoning navigation. Apart from a known starting position, two data are required - the direction being followed and the distance travelled. These data are varying with time and every change of heading. The individual distances travelled with different headings are reckoned up following the rules of vector addition. With a given starting point, the actual position of the vehicle is obtained at the same time. The system has now been tested for more than one year. The navigation errors in the average are 3 % of the distance travelled. The system has proven to be of great help in finding unknown destinations in foreign towns.
