Kinetic Model-Constrained Robust In-Motion Alignment for Projectiles SINS/GNSS

Rapid and accurate initial alignment is a critical prerequisite for the performance in integrated navigation of strapdown inertial navigation system (SINS) and global navigation satellite system (GNSS), particularly in guided projectiles operating under in-motion conditions. However, conventional op...
