Locating device for a motor vehicle with a satellite receiver and detection method

to calculate position-finding device for a motor vehicle, having a satellite receiver, preferably for receiving signals of the GPS and / or GLONASS satellites, the satellite receiver is designed for a suspected position of the motor vehicle from the received signals subject to tolerances directions of travel in the manner of a travel direction fan , with a displacement sensor, with a direction of travel sensor, with a digital road map and having a computer for determining the actual travel direction at the suspected position of the motor vehicle, characterized in that - is formed of the computer (5), for the roads (21, 22, 24) of a subregion of the digital road map a main path (21) and maglicherweise one or more secondary paths (22) to determine on which the instantaneous position of the motor vehicle is suspected . - that the computer (5) is further adapted to compare the directions of the main path (21) and the secondary paths (22) with the travel direction fan (20) of the satellite receiver (2), wherein the directional fan (20) is prioritized so that only the main path (21) and the secondary paths ...
