Abstract
Flight experiments have been conducted at the Sendai airport using the experimental research aircraft Dornier-228-200 (Do-228) of National Aerospace Laboratory (NAL). The objective is to evaluate new navigation sensor technologies which will play a key role in the design of HOPE (H-II Orbiting Plane) approach/landing (A/L) navigation system. The navigation sensors tested include Microwave Landing System (MLS), Global Positioning System (GPS), Inertial Navigation System (INS), and radar altimeter. Differential GPS (DGPS) is also tested in both standalone and hybrid modes. During the flight the Do-228 is tracked by a laser tracker. Tracker data are used to provide reference trajectories of the aircraft. Navigation accuracy is evaluated as the difference between reference trajectory and navigation output from respective navigation sensors or hybrid systems in the post-flight analysis. This comparison becomes possible if we could establish a, common reference navigation frame on which all navigation outputs are transformed. Since GPS provides absolute position and velocity with respect to the World Geodetic System 1984 (WGS84), while others generally provide relative position (and velocity) information, it is convenient that such a navigation frame is referenced to the WGS84 system. In this paper, a method based on GPS surveying is proposed and applied to establish such a reference frame and position coordinates of the groundbased navigation-aid facilities. An example of application of the surveying results is presented which evaluates standalone GPS navigation accuracy for the A/L flight phase.
