The article describes the Landfall vehicle location system developed by Marconi Research Laboratories. The in-vehicle system is based on the principle that fleet vehicles are usually restricted to an existing urban road network. In addition to sensors for distance and direction the system uses a stored map database comprising the roads (links) and junctions (nodes). Any road network is regarded as a network of nodes containing inlet/outlet ports and Interconnected links. The tracking algorithm is based on a step-by-step distance-turn-distance-turn process supported and constrained by stored map data. Landfall (links and nodes database for automatic land vehicle location) is a system concept and the tracking unit, driver terminal, telemetry link and database processing are all independent and replaceable modules. The basic landfall system is able to offer in-vehicle route guidance from location data keyed in through a status initialization device or transmitted over a telemetry link. /TRRL/
