초록

An inertial reference system for determining the attitude and rate of change of attitude of a vehicle such as an aircraft is disclosed. Redundancy of the inertial reference system may be accomplished by replacement of one of the fiber opticgyroscopes of an otherwise dual fiber optic gyros installation with a low-cost reference IMU. Failure detection and isolation of a fiber optic gyroscope system may be accomplished with a low-cost reference IMU rather than with an additional fiber optic gyroscope. The information provided by the eliminated fiber optic g...

[ What is claimed is:] [1.] A high integrity sensor system consisting of:a precision sensor system, a less precise secondary sensor system, and means to allow detection of a fault in the precision sensor system by utilizing signals from both sensor systems, wherein said means to allow detection of a fault utilizes a short-term stability characteristic of said secondary sensor system to detect faults while concomitantly correcting longer-term errors in said secondary sensor system.
