- In the inertial navigation system, the altitude error diverges exponentially if
external sensors do not compensate it. To suppress divergence of the error, non-inertial
aiding sensors that provide vertical information are utilized. With these sensors, the wellknown
baro-inertial damping loop or the well-known Kalman filter mechanization can be
constituted to compensate the error of the vertical channel. In this paper, a new error
compensation scheme for INS vertical channel is proposed, especially with a barometer
and GPS by fusing the two well established methods. The performance of the proposed
scheme is analyzed by computer simulation.
