Abstract

global multimedia mobile satellite communications service with a user data rate around 2 Mbps for handy terminals. The target year for commercial implementation is 2010. Nextgeneration LEO System Research Center (NeLS) was formed in the end of 1997 as a research group under the Telecommunications Advancement Organization of Japan (TAO), in cooperation with the telecommunications operators, manufacturers, universities and governmental research organization. In prosecuting this project, two-phase approach, phase 1 and phase 2, is considered. Phase 1, which is the system definition and development of key technologies, has been completed. From last year Phase 2 has started to develop flight hardware targeting in orbit demonstration around
