Abstract:	Abstract: The National Space Development Agency of Japan (NASDA) is developing a GPS receiver for its H-IIA rocket. The GPS is used for the H-IIA rocket to measure its position and velocity on the trajectory. Navigation solutions of GPS are used for the primary data source of range safety for the downrange area. Therefore the onboard GPS equipment is designed to be independent of the vehicle guidance and control system. The existing radars are also used as the data source of range safety for the uprange area. The H-IIA rocket had a great success for the first test flight on 29th Aug, 2001(Fig.1). The implementation of GPS will lead to greater flexibility at lower operation costs. Requirement specification, system analyses and implementation of the GPS receiver for the H-IIA rocket are presented in this paper. And the flight results of the first flight and its evaluation are also presented.
