Query: A Globally Exponentially Stable Hybrid Attitude and Gyro-bias Observer   This paper presents a hybrid attitude and gyro-bias observer designed
directly on the Special Orthogonal group SO(3). The proposed hybrid observer,
relying on a hysteresis-based switching between two configurations, guarantees
global exponential stability using biased angular velocity and inertial vector
measurements. Simulation results are given to illustrate the effectiveness of
the proposed observer.
