Sensor fusion for navigation of an autonomous unmanned aerial vehicle

This paper presents the position and velocity determination by using INS and GPS. The measurement results from INS and GPS sensors are fused by using Kalman filter. Dilution of Precision (DOP) technique is used to select a combination of satellites to be used as measurement data. Two implementations of Kalman filter, feedforward and feedback are used. The experiment shows that the selection of the satellites affects the measurements. The methodology and experiments presented in this paper has been developed and tested for the autonomous Unmanned Aerial Vehicle (UAV).
