Abstract(in Japanese) (See Japanese page)
Abstract(in English) An atomic clock is one of the most important key technology of a satellite positioning system. In Japan, however, no satelliteborne atomic clock has been developed, though atomic clocks for ground use have been developed. A report of the Space Activities Commission in 1997 has changed this situation and triggered the research and development of a spaceborne atomic clock in Japan. In this paper, the technologies of atomic clocks are reviewed and the research activities of a spaceborne hydrogen maser at Communications Research Laboratory are reported.
