Vertical channel damping loop design using vertical position and velocity information

In this paper, a vertical channel damping loop design using vertical position and velocity information is newly proposed. The inertial navigation system (INS) for the position, orientation, and velocity is mostly used for various platforms. The main disadvantage of the INS is that the navigation information degrade with time. Especially, the vertical channel error diverges exponentially if external sensors do not compensate it. The proposed method uses vertical position and velocity information acquired by additional sensors. The Kalman filter is constructed to calculate vertical channel damping loop gains. The proposed method is simulated by using INS and additional sensors error statistics. Results demonstrate the usefulness and practicality of the proposed method.
