  • Accuracy of a fiber optic gyro
    Patent number: 5812263
    Abstract: In a fiber optic gyro (FOG) with a photo-diode phase detector that produces a detector signal that is supplied to an A/D converter to generate a FOG information signal for use in a signal processor to produce a FOG control signal based on FOG controller equations, the photo-diode out is summed with a feedback signal from the signal processor to reduce a DC offset in the input to the A/D converter.
    Type: Grant

  • Fiber optic gyro digital control with rate extension
    Patent number: 5513003
    Abstract: A digitally operated fiber optics gyro system in which the 2.pi./SF rate limit has been removed by storing the number of 2.pi. reset that have occurred and combining this with the signal sensed by the light sensor.

  • Calibration of an internal sensor system
    Patent number: 5421187
    Abstract: A calibration device for establishing a 3-D reference frame for an inertial sensor system. A secondary mounting surface on the calibration device is used to provide a measurement of the reference line required for inertial system installation alignment. This device provides a means for establishing a highly accurate alignment of inertial system sensors relative to the output coordinates, called the "mounting frame", without a requirement for optics or a manual transfer of data. By rotating the inertial sensor system through use of a rate table into planes which are substantially perpendicular to each other, the mounting frame for the sensor system can be established.
