Abstract
A method of determining a position of a vehicle on a guideway includes detecting a position of the vehicle relative to a first reflective positioning element along the guideway. The method also includes detecting a unique identification code of a transponder along the guideway, wherein the transponder is located a first known distance along the guideway from the first reflective positioning element. The method further includes determining the position of the vehicle, using a position determining system, based on a modulated reflection signal received from the transponder, a first non-modulated reflection signal received from the first reflective positioning element, and the first known distance.
