Skewed axis inertial sensor geometry for optimal performance
Abstract
The skewed axis inertial sensor geometries considered in the literature are reviewed. They are shown to be members of two general classes of sensor geometry. Two quantitative measures of sensor geometry performance are developed: state estimation performance and fault detection performance. The concepts of uniform state estimation and uniform fault detection are defined. Reduced sensor geometries occurring after a sensor failure are discussed. The various sensor geometries are compared to select optimal 3, 4, 5, and 6 sensor configurations.
