Position Location in AHS by Magnetic Pseudo-Noise Signals

In this paper, the authors present a new method for position location by automated vehicles in an automated highway system (AHS). The method makes use of the infrastructure and characteristic of the automated roads by using magnetic roadway markers as a medium to carry the signals from pseudo-noise codes that measure range. The magnetic pseudo-noise signal, unique for each lane in the network, by estimating the signal phase, allows a vehicle to resolve its absolute position on the road. The system is able to detect positioning errors in a short amount of time and can also correct them.
