A Fast In-Field Coarse Alignment and Bias Estimation Method for Stationary Intermediate-Grade IMUs

This paper presents an innovative in-field coarse bias estimation (CBE) method for stationary intermediate-grade inertial measurement units (IMUs), which is based on the existence of normality and orthogonality errors in the attitude matrix supplied by the traditional three-axis attitude determinati...
