Gradient Descent Optimization-Based SINS Self-Alignment Method and Error Analysis
In this paper, the self-alignment for stationary strapdown inertial navigation system (SINS) is formulated as an optimization problem, and two gradient descent optimization-based SINS self-alignment methods (GD1 and GD2) are proposed. The highlight lies in that two quaternion-based objective functio...
