Abstract:

A high precision vehicle localization system, including a GPS Unit configured to receive GPS signals from a GPS satellite for determining a GPS location of the vehicle, an inertial measuring unit (IMU) configured to collect vehicle inertial information, an electronic communication module configured to receive GPS correction data wirelessly from a remote source, and a controller in communication with the GPS Unit to receive the GPS signals, the IMU to receive the vehicle inertial information, and the electronic communication module to receive the GPS correction data. One of the GPS Unit and controller is configured to process the GPS signal to determine the GPS location of the vehicle. The controller is configured to fuse the GPS location of the vehicle, the inertial information, and the GPS correction data such that the accuracy or precision of the GPS location of the vehicle is increased.
