Initial Results of the First QZS (Michibiki) Time Management System

National Institute of Information and Communications Technology, Japan (NICT) developed the time management system of the first Quasi-Zenith Satellite (QZS-1), which consists of on-board time transfer subsystem (TTS) and related ground systems such as time management stations (TMS). NICT also manages the TTS and TMS. This paper describes about the check out status and some initial results of the time comparison experiments.
