Experimental Results of Time Comparison Using the Time Comparison Equipment on Board ETS-Ⅷ

摘要

The Engineering Test Satellite type VI (ETS-VI) was a geo-synchronous satellite launched on December, 2006.Using ETS-VI, mobile telecommunications experiment using the large deploy-able antennas is executed.ETS-VI is first satellite in Japan bearing atomic clocks, and basic experiments of satellite positioning are carried out. In National Institute of Information and Communications Technology (NICT), highly precise time and frequency comparison experiment between the satellite and the ground is executed for the first time in the world.Highly precise time comparison experiment between ground stations using an on-board bent-pipe function and ranging experiment are also executed.
