A navigation system is provided. A GNSS receiver is used to receive satellite signals from a plurality satellites and an local positioning system (LPS) receiver is used to receive LPS signals from a plurality of fixed location LPS transmitters that are positioned to form an LPS coverage region. A controller is in communication with the GNSS receiver and the LPS receiver. The controller is configured to use LPS signals to determine a location of the vehicle when the vehicle is within the LPS coverage region and within a GNSS denied coverage region. The LPS coverage region is a region that provides the LPS signals from at least four fixed location LPS transmitters. Each LPS signal from each LPS transmitter includes LPS transmitter location information and clock information used by the controller of the vehicle to determine the location of the vehicle.
