In this video we continue our discussion on how to track the attitude of a body in space using quaternions. The quaternion method is similar to the Euler Kinematical Equations and Poisson’s Kinematical Equations in that it consumes rate gyro information to compute Euler angles. However, it has advantages in that it is robust to singularities in orientation that plague the Euler and Poisson techniques.
