Flight experiments have been conducted at the Sendai airport using the experimental research aircraft Dornier-228-200 (Do-228) of the National Aerospace Laboratory (NAL). The objective is to evaluate new navigation sensor technologies which will play a key role in the design of terminal area navigation systems for aerospace vehicles including HOPE (H-II Orbiting Plane). The navigation sensors tested include Microwave Landing System (MLS), Global Positioning System (GPS), Inertial Navigation System (INS), and radio altimeter. Differential GPS (DGPS) is also tested in both stand alone and hybrid modes. In this paper, a method based on GPS surveying is proposed and applied to establish a reference frame and position coordinates of the ground-based navigation-aid facilities. Examples of application of the surveying results are presented which evaluate stand alone GPS navigation accuracy of NAVCORE-1 GPS receiver for the approach/landing (A/L) and orbit flight phases.
