ABSTRACT:
A current location indicating apparatus for use in an automotive vehicle wherein a current location of the vehicle is arithmetically obtained in terms of two-dimensional coordinates by a signal processing unit on the basis of the outputs from a travel distance detecting unit and a bearing detecting unit, and the current location of the vehicle is visually indicated on the screen of a display unit from the thus-obtained data in connection with the current location of the vehicle. The apparatus comprises a first bearing detecting unit comprising a rate type gyroscope as a main unit, and a second detecting unit comprising an earth magnetism sensor. The signal processing unit is adapted to monitor the outputs from the first and second bearing detecting means in comparison with each other to determine whether or not the first bearing detecting unit is under the influence of any disturbances, whereby the output of the first bearing detecting unit can be corrected so as to be free from any substantial disturbances during operation.
