Quaternion-Based Kalman Filter for AHRS Using an Adaptive-Step Gradient Descent Algorithm
This paper presents a quaternion-based Kalman filter for real-time estimation of the orientation of a quadrotor. Quaternions are used to represent rotation relationship between navigation frame and body frame. Processing of a 3-axis accelerometer using Adaptive-Step Gradient Descent (ASGD) produces...
