The integrated navigation system, consisting of barometric altimeter (Baro) and GPS, is presented. The integration is achieved by using a Kalman filtering type data fusion algorithm. The proposed data fusion algorithm utilizes the barometric altimeter and GPS measurements in the estimation procedure in order to increase the altitude estimation accuracy. The performance of the proposed Baro/GPS integrated system is evaluated by the simulations for altitude estimation of an aircraft.
