In Global Navigation Satellite System (GNSS) technology, the accuracy of positioning signals (time reference clock signal) is very important. To improve the accuracy of the positioning signals, exact time control of the satellite and highly accurate clock synchronization between satellite and ground stations are required. JAXA plans to conduct a time synchronization experiment for future positioning satellite technology. This experiment consists of a time synchronization experiment and time management using atomic clock onboard a geostationary satellite, which is always visible at high elevation angle. JAXA also wants to confirm whether a geostationary satellite is useful for the positioning accuracy improvement if it is used as a positioning satellite. This clock management technology will be utilized in the quasi-zenith satellite, which is studied in Japan, in the future. In this symposium, the result of preliminary experiment and experiment outline is reported
