Abstract:
Disclosed is a positioning system and a node network. A terminal included in the present invention is characterized by an invisible light sensing unit that detects invisible light signals, that were emitted from one or more signaling nodes with the same intensity, carrying the location data of each signaling node; and a controller that calculates the user's position based on the location data included in one or more invisible light signals and their received signal strength.
