  • Patent number: 5337243
    Abstract: An object of the present invention is to provide precise calculation of a position and an orientation of a vehicle running or moving on route. Regarding the vehicle moving along a given route and with possible variations in the running orientation it is judged that the vehicle has moved substantially on a straight line when an integrated value of the orientation variations is smaller than a predetermined value. By obtaining a regression line of GPS receiving positions in the straight line, a precise orientation of the vehicle is obtained by adding a difference between the orientations of the straight line and the regression line to an original orientation of the vehicle.

  • Patent number: 5337142
    Abstract: The invention concerns an optical fiber measuring device, for example a gyrometer. The working of this device is independent of possible variations in the spectrum of the source. It includes a narrow, stable spectral filter which separates the incident flux. The modulation chain is slaved by a first detector (3). A second detector (23) receives the filtered flux. Its response is processed by a device (219) which supplies a signal that is a function of the spectrum of the light source (1).
