Measurement and Correction Method of the System Time Offset of Multi-mode Satellite Navigation

摘要：

　　Multi-mode satellite navigation is an important development direction of Global Navigation Satellite Systems (GNSS).Because of each satellite navigation system owing an independent and stable operating system time scale,one of key issues that must be solved to implement multi-mode navigation is to determine the system time offset between two satellite navigation systems.National Time Service Center (NTSC) keeps our country’s standard time (UTC (NTSC)).It is an available resource for us to monitor the system time offset of satellite navigation systems by means of receiving signal-in-space using the geodetic time receiver.The monitoring principle and main measurement errors are discussed.The correction method of system time offset measuring results is studied with the IGS precise orbit ephemeris.In order to test rationality of the measurement method,circular T bulletin data published by Bureau International des Poids et Mesures (BIPM) is applied to compare with the monitoring data and revised data.Data Processing results are given and shown that this monitoring method is practical and can be applied to multi-mode navigation.
