Abstract:	NAL and NASDA develop High Speed Flight Demonstrators (HSFDs) to examine an automatic take-off and landing technology (Phase I) and to measure the transonic aerodynamic characteristics of a reusable space plane for getting the reference data for a CFD (Computed Fluid Design) technology (Phase II). For HSFD navigation, we develop a GPS aided inertial navigation system (GAINS) whose distinctive feature is using the carrier-phase DGPS (CDGPS)/ INS hybrid navigation technology. This paper describes the design of GAINS. We show its accuracy, integrity and continuity performances that are analyzed by computer simulations using the covariance analysis technique. Ground and flight tests are also carried out to confirm the performance of the GAINS flight model. Both results prove that GAINS meets the requirements of the navigation performance under severe flight conditions of HSFD.
