The present invention provides a navigation system, apparatus, and method. The navigation system includes a global navigation apparatus, a first roadside navigation apparatus, and a terminal navigation apparatus. The terminal navigation apparatus is configured to send, to the global navigation apparatus, a global path request used to request for a road-level global path. The global navigation apparatus is configured to: determine the global path according to the global path request, and send, to the terminal navigation apparatus, first indication information used to indicate the global path. The first roadside navigation apparatus is configured to: determine a lane-level local path according to the global path, and send, to the terminal navigation apparatus, second indication information used to indicate the local path.
