  • Omni range inclino-compass
    Patent number: 5287628
    Abstract: A solid-state omni range incline-compass having a gravity sensor and a geomagnetic flux sensor provided on, each of three orthogonal axes established on a moving body a unit for generating a mathematic horizontal plane by making a gimbal mechanism as a mathematic equation on the basis of outputs from the gravity sensor located on each of the three orthogonal axes and a unit for calculating an azimuth angle of the moving body on the basis of two orthogonal axes on the mathematic horizontal plane.
