Abstract
A position finder for vehicles includes, connected to an antenna, a satellite receiver for receiving and evaluating transmitted signals sent by a plurality of satellites, additional sensors for detecting the movement of the vehicle, and a coupler computer, for joint evaluation of the transmitted signals sent by the satellites and of the sensor signals so that instantaneous positional data can be generated. To design less expensive position finders for vehicles, the position finder is characterized in that the additional sensors are sensors that are independent of the vehicle system and the satellite receiver, along with its antenna, the additional sensors and the coupler computer, are arranged in a separate housing having a terminal for a power supply voltage and an interface via which the positional data can be sent.
