Based on theories of H-infinity filter and sigma point transformation, a sigma point H-infinity filter method is proposed. The error model of marine strapdown inertial navigation system on the swaying base is nonlinear, whereas the azimuth angle is large. Because during the deduct of the error model higher order terms are neglected, and the practical noises(More)
In order to overcome the limitation of single sensor in vehicle integrated navigation system, cascade fusion architecture is proposed to enhance the reliability of location information. Our research is focus on the algorithm in decisionmaking level of the fusion architecture, which is used to fuse the information from Global Positioning System (GPS), Kalman(More)
