For a reusable space plane, GPS navigation is essential for accurate onboard navigation. Moreover, if GPS navigation with Differential GPS (DGPS) technique performs high navigation accuracy and can be applied to the landing phase, the onboard GN & C (Guidance Navigation and Control) system of the space plane is simplified and its weight is reduced. NAL and NASDA have been studying the GPS navigation for an automatic landing. As one of the research items of the Automatic Landing Flight Experiment (ALFLEX), the pseudolite DGPS system for ALFLEX was designed and manufactured, and its function and performance were evaluated by using real flight data. This paper outlines the pseudolite DGPS system for ALFLEX and evaluates the results of the performance of the DGPS navigation, the carrier smoothing DGPS navigation, the IMU (Inertial Measurement Unit)-DGPS integrated navigation, and the multipath effect on the pseudolite signal.
