An Intuitive Approach to Inertial Sensor Bias Estimation [PDF]
, 2013 A simple approach to gyro and accelerometer bias estimation is proposed. It does not involve Kalman filtering or similar formal techniques. Instead, it is based on physical intuition and exploits a duality between gimbaled and strapdown inertial systems.
