This paper summarizes the flight evaluation of the DGPS-INS hybrid navigation system conducted as a preliminary study for constructing a next-generation navigation system at the National Aerospace Laboratory (NAL). First, the configuration used in the flight experiments, including ground facilities and the measurement systems, is described. Secondly, the design concept for a method of estimating navigation errors using a Kalman filter is presented. Thirdly, flight profiles employed in the experiments are defined, and the experimental results of GPS, DGPS, INS in both stand-alone and hybrid modes which correspond to each profile are shown. Also, improvement in navigation performance by introducing the DGPS-INS hybrid navigation system available for future space vehicles has been successfully completed.
