The invention is a navigation system for land vehicles. Prior methods of determining vehicle heading have been either too expensive or too inaccurate for widespread use in automotive vehicles. The novel aspect of this invention is that it determines vehicle heading by utilizing an inexpensive angle-of-deflection transducer connected to the vehicle steering wheel, and a microcomputer with a look-up table to compensate for the nonlinear relationship between the angle of deflection of the steering wheel or linkage and that of the road wheel. The system comprises a distance transducer, a steering wheel look-up table, and a positioning display. The signal processor operates on distance information and heading information from the transducers, the look-up table compensates for the nonlinear relationship between the steering wheel angle and the angle of the road wheel, and the resulting position information is displayed.
