1. A route data base generating system for use in an area having impaired reception of navigational signals emanating from satellites associated with a global positioning system, said route data base being based on a division of the route into a plurality of linear segments that are interconnected and arranged in an end-to-end serial order and comprising data that includes the lengths and opposite end coordinates of the linear segments in the serial order arrangement, said generating system comprising:

  • (a) a vehicle moveable over the course of the route for generating such distance movements and heading changes and having rotatable means with rotatable movements that are equatable to distance movements and heading changes of the vehicle during its movements over the course of the route,(b) computer means operatively connected to said rotatable means for generating data relating to the lengths and orientations of the linear segments in the serial order without dependency upon geo-magnetic or gyroscopic forces during such movements of the vehicle over the course of the route, and(c) data storage means operatively connected to said computer means for receiving and storing the data relevant to the linear segment lengths and opposite end coordinates generated thereby during the traversal of the route by the vehicle.
