摘要
In this paper, the observability and the degree of observability for stationary SDINS error are analyzed. The use of the Lyapunov transformation is proposed for transforming the conventional SDINS error model and the sufficient conditions for the observability of SDINS error model are analytically derived. A complete characterization for the degree of observability during two position alignment is presented which allows us to predict the performance of two position alignment in SDINS.
