Coarse alignment of marine strapdown inertial navigation system using the location of fitted parametric circle of gravity movement

This paper presents a novel estimation method for coarse alignment of a marine strapdown inertial navigation system (SINS) under mooring conditions. The properties of gravitational motion are used to improve the accuracy of coarse alignment. The parametric motion of gravitational apparent is a circl...
