Abstract
The present invention discloses a radio beacon coupled to an altimeter, for GPS positioning in an elevator, configured to broadcast signals forcing a nearby GPS receiver to read constant latitude and constant longitude, associated with the position of the elevator shaft, and altitude associated with the altimeter reading. The acquired in-elevator position can serve as an initial fix for further navigation, particularly indoors.
