In this paper, observable degree of SINS based on singular value decomposition (SVD) is analyzed during initial alignment, and an improved method using the right singular vectors to calculate the observable degrees is proposed. Firstly, an error model is introduced for SINS on rocking base. Secondly, the model is demonstrated to satisfy the piece-wise constant system (PWCS) analysis law. Thus, the observability of system states can be simply analyzed by using the stripped observability matrix… CONTINUE READING
