First Claim
1. A navigation system, the system comprising:
- a global navigation satellite system receiver adapted to output information representing the location of a vehicle based on one or more signals from one or more satellites;
an ultra-wideband ranging system adapted to output information representing the location of the vehicle based on one or more ultra-wideband signals; and
a vehicle guidance system coupled to receive the location output from the global navigation satellite system receiver and the location output from the ultra-wideband ranging system;
wherein the vehicle guidance system is adapted to maneuver the vehicle based on the information from at least one of the global navigation satellite system receiver and the ultra-wideband ranging system based on a distance of the vehicle from a target object.
