EP0243635A3

Roadside beacon system

Abstract

A navigation system in which road side antennas transmit both position calibrating data and local information to navigator devices installed in traveling vehicles. The navigator devices process the local information when the signal received from any of the antennas is above a relatively low level but processes the position calibrating data only when the signal is above a relatively high level, whereby recalibration is performed only in the immediate vicinity of one of the antennas but local information is received over a wider area.
