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.

Locating device for vehicles

A position of a vehicle is determined by outputting position signals by a reception antenna and outputting traveling condition values by traveling condition sensors of a vehicle for determination of an absolute position of the vehicle and outputting an absolute position signal, from the absolute position signal and predetermined reference data of a reference system determining a relative position of the vehicle in the reference system, determining a position quality signal from a comparison of the absolute position signal and a reference position signal, and using the position quality signal for determination of an absolute position of the vehicle.

Method of and device for determining a position of a vehicle

The data receiver device (,) of the present invention for reception of radio signals containing correction data for a global navigation satellite system includes at least two different radio receiving circuits (,) operating in three different frequency bands for receiving the radio signals containing the correction data; at least one demodulator (,) for conversion of these radio signals to a baseband; a memory for a frequency table (,) of frequencies of at least two different sources of the radio signals and for a decoding table (,) for decoding the radio signals and at least one decoding device (,) for decoding of the correction data from the radio signals. The at least one decoding device (,) is connected with the at least one demodulator (,) to receive the radio signals from it on the baseband and with the memory (,) for the decoding table for decoding of the radio signals.

Method and data receiver device for reception of a radio signal containing correction data for a global navigation satellite system

A location sensor in which a satellite receiver, a rotation rate sensor constituting a direction sensor, and an acceleration sensor constituting a displacement sensor are arranged in a housing. The signals of these sensors are conveyed to a common filter, so that the location, the movement velocity, and/or the movement direction can be picked off at the output of the location sensor. The compact arrangement of the individual sensors makes possible multiple utilization of individual components, for example of filters.

Location sensor having a satellite receiver for position determination

A method for initialization of a receiver, and a receiver of position signals, are proposed, a sequence of transmitter identifiers being searched through for an active transmitter, and the sequence of transmitter identifiers comprising satellites which are positioned in orbits that are located approximately perpendicular to one another.
