In order to improve the accuracy of initial alignment which determines the accuracy of navigation, a Sage-Husa adaptive kalman filter algorithm is applied to SINS initial alignment of single-axis rotation system. The simulation result further shows that in the case of inaccurate statistical property of noise, the estimation accuracy of Sage-Husa adaptive kalman filter is better than the conventional kalman filter.
Rotation direction of single-axis rotation SINS is researched in this paper. The two aspects: one-way, positive and negative rotation and clockwise, counterclockwise rotation are deeply analyzed respectively, and experimental verification is also taken. The results show that: FOG-based single-axis SINS should rotate with the positive and negative rotation way. It has a significant meaning to the engineering application of this technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
