A navigation system for use on an automated vehicle includes a global-positioning-system-receiver (GPS-receiver), a vehicle-to-vehicle-transceiver (V2V-transceiver), an object-detector, and a controller. The GPS-receiver indicates a receiver-coordinate of a host-vehicle. The receiver-coordinate is characterized by a receiver-error. The V2V-transceiver receives a GPS-coordinate from each of a plurality of other-vehicles proximate to the host-vehicle. The object-detector determines a distance and a direction relative to the host-vehicle to each of the plurality of other-vehicles. The controller is in communication with the GPS-receiver, the V2V-transceiver, and the object-detector. The controller is configured to adjust each GPS-coordinate from each of the plurality of other-vehicles based on the distance and the direction and thereby provide a plurality of adjusted-GPS-coordinates that coincide with the host-vehicle, and combine the plurality of adjusted-GPS-coordinates with the receiver-coordinate to determine a host-coordinate that is characterized by a location-error less than the receiver-error.
