FLIGHT EVALUATION OF GPS-DGPS SENSOR SYSTEM INSTALLED IN NAL DO228

Navigation systems have been tested with a Dornier 228-200 (D0228), experimental research airplane of National Aerospace Laboratory (NAL) at Sendai Airport, Japan. A clear and acquisition (C/A) code signal channel global positioning system (GPS) receiver was installed in the Do228. This receiver can operate in real-time differential GPS during differential corrections coming from GPS base station operated at a known position. The base station will track up to four visible satellites and measure the error in pseudo-range to each tracked satellite, based on broadcast ephemeris data and known positions. A laser tracker was used to determine a reference trajectory of the airplane. The paper describes GPS/DGPS accuracies during approach and landing of the aircraft.
