Electromagnetic wave propagation in urban areas is discussed in relation to vehicle location. Current methods are reviewed for vehicles on a arbitrary route. Isophase and hyperbola systems are compared. The isophase system is more accurate. A correction procedure for multipath induced errors is presented, based on measuring time signals from four transmitters. The use of measured times in order to reduce location errors caused by propagation anomalies is described. The methods were tested on a simulated city area covered by transmitters on the corners of a 25 km square. Results are inconclusive.
