RISObservability and Estimation Error Analysis of the Initial Fine Alignment Filter for Nonleveling Strapdown Inertial Navigation System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, performance of the initial fine alignment for the stationary nonleveling strapdown inertial navigation system (SDINS) containing lowgrade gyros is analyzed. First, the observability is analyzed by conducting ...
Adaptive Redundant Inertial Measurement Unit/Global Positioning System Integration Filter Structure for Fault Tolerant Navigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a new adaptive filter structure containing two subfilters, a fault detection and isolation (FDI) filter, and a mainfilter for redundant inertial measurement unit (RIMU)/global positioning system (GPS) ...
