ABSTRACT:
The present invention operates on the principle that the velocity vector of a land-vehicle is along the longitudinal axis of the vehicle. The invention uses an odometer in conjunction with a set of three single axis rate gyros strapped down to the vehicle to provide a land vehicle navigation system. The single axis rate gyros are rigidly mounted to the body with input axes parallel to a set of reference axes in the vehicle. By means of these gyros it is possible to infer the heading of the vehicle and thereby achieve a navigation accuracy comparable to the accuracy that the same gyros would provide in a gimballed system, but without the necessity for the set of gimbals.
