Abstract
An apparatus is provided for determining the velocity and orientation of a vehicle, for instance to permit route guidance by dead reckoning. Two optical speed over ground sensors on the vehicle are arranged at acute angles to the longitudinal axis of the vehicle. One or more further sensors, such as a fibre optic gyroscope or one or two optical speed over ground sensors, are provided on the vehicle. The speed and direction from these sensors can be used by a data processor to perform dead reckoning navigation and the vehicle position can thus be determined.
