ABSTRACT	Flight experiments have been conducted at the Sendai airport using the experimental research a radio 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 to provide reference profiles of the aircraft.In these experiments,navigation accuracy is evaluated as the difference between the reference profile and navigation output from respective navigation sensor or hybrid systems in the post-flight analysis mode.This comparison is not possible without establishing a common reference navigation frame on which all navigation outputs are transformed.In this paper,a method based on GPS surveying is proposed and applied to establish such a reference frame and position coordinates of the ground-based navigation-aid facilities.Examples of application of the surveying results are presented which evaluate standalone GPS navigation accuracy of NAVCORE-1 GPS receiver for the approach/landing(A/L)and orbit flight phases.
