New algorithm for gyroless spacecraft angular rate Estimation and its application

A new algorithm for estimating the angular velocity using quaternion measurements is developed based on the concept of the global optimality resulting when using a centralized or master Kalman filter. The new filter consists of three local Kalman filters run in parallel. Each of them feed a mas...
