Abstract
A system and method are provided for determining the position of a vehicle on a guideway. For operation, the vehicle includes a magnet system having a wavelength 'λ'. Further, the guideway includes a propulsion winding for carrying a propulsion current. Structurally, the propulsion winding includes a series of sections, with each section having a wavelength 'λ'. Further, the propulsion winding includes “N” coils linearly aligned along the guideway, with a phase difference of “λ/N” between adjacent coils. Importantly, a transmitter is located on the vehicle for emitting a position current that interacts with the propulsion winding to produce a signal in each coil. Also, the system includes a trap connected to each coil for receiving each respective signal, and a processor for resolving the respective signals to determine the position of the vehicle on the guideway.
