ABSTRACT	Flight experiments conducted at the Sendai airport(under a joint research project with NAL,NASDA,and ENRI in partial co-operation with Toshiba and NECe microwave landing system(MLS),global positioning system(GPS),inertial navigation system(INS),and radio altimeter.The differential GPS(DGPS)was also tested in both stand-alone and hybrid modes.The Do-228 is tracked during flight by a laser tracker,with subsequent data being used to provide a reference profile of the aircraft.Navigation accuracy is evaluated in the post-flight performance analysis as the difference between reference profile and navigation output from each navigation sensor or hybrid system.This comparison is made in the runway coordinate system(RCS),a reference navigation coordinate system which corresponds to the World Geodetic system 1984(WGS84).The RCS was constructed using GPS interferometric positioning.This report describes the flight testing methodology employed for evaluating A/L navigation system performance and also the flight experiments conducted in 1990.Emphasis is placed on describing the tested navigation sensors,data acquisition systems,groung guidance facilities,flight patterns,and analysis strategies.Some preliminary analysis results are also presented which evaluate the stand-alone performance of each navigation sensor as well as a hybrid GPS-INS system.
