Abstract
Novel Analytic Coarse Alignment Method is presented for Strapdown Inertial Navigation Systems (SDINS) alignment on oscillatory base. Oscillatory base alignment is conducted by building two vectors derived from gravity and angular velocity information provided by the strapdown INS under oscillatory motion and comparing them with similar vectors built using the local level reference frame information. The theory and algorithms are detailed in the paper and several simulation test results are compiled for various kinds of oscillatory motion.The proposed algorithm could be used for sea based INS applications.
