DEVELOPMENT OF A SPACEBORNE HYDROGEN MASER ATOMIC CLOCK FOR QUASI-ZENITH SATELLITES

摘要

A Bread Board Model of a spaceborne hydrogen maser atomic clock for the satellite positioning system using Quasi-Zenith Satellites has been developed. Anal- ysis and experiments for technical problems such as miniaturization, achievement of long life, mechanical vibration prooˉng, and space environment characteristics have been performed, and technical data necessary for EM development have been obtained.
