Analysis and Evaluation of One-Way Time Service by Beidou Dual-Frequency Multichannel Receiver
Abstract:
High precision time plays a key role in technology and economy domain. as the time transmitting carrier, time service restricts timing precision of users. Combined with the characteristics of Beidou navigation system, the paper describes the one-way time service theory, accomplishes Beidou one-way timing algorithm and the software design. Finally, using the satellite data of Beidou dual-frequency multichannel receiver at the National Time Service Center (NTSC), the Chinese Academy of Sciences, the precision of Beidou one-way time service by the different types of satellites-GEO satellites, IGSO satellites, GEO combined with IGSO satellites-is analyzed and evaluated. The experiment result will provide important reference for optimizing the function of Beidou one-way time service.
