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.
Claims1
A solid-state omni range inclino-compass comprising:
- (a) a gravity sensor and a geomagnetic flux sensor provided on each of three orthogonal axes established on a moving body;
- (b) means for generating a mathematic horizontal compass by making a gimbal mechanism as a mathematic equation on the basis of outputs from said gravity sensor located on each of said three orthogonal axes;
- (c) means for calculating an azimuth angle of said moving body on the basis of two orthogonal axes on said mathematic horizontal compass.
