用于JATC的GPS CV时间比对中的数据处理

Data Processing for GPS Common View Time Comparison Between Remote Clocks

GPSCV(共视)时间传递技术将在重建的我国的综合原子时(JATC)系统中起重要作用。介绍了GPSCV时间比对中共视数据的选取和消除观测数据中的随机噪声的方法,对GPS共视时间比对中的电离层时延改正和几何时延改正方法作了阐述,给出了对NTSC(中国科学院国家授时中心)与CRL(日本通信研究所,现已更名为国家信息和通信技术研究院(NICT))两个时间实验室之间的共视比对数据的计算结果。

GPS CV method will play an important role in JATC(joint atomic time of China) system which is being rebuilt.The selection of common view data and the methods of filtering the random noise from the observed data are introduced.The metheds to correct ionospheric delay and geometric delay for GPS CV comparison are expounded.The calculation results for the data of CV comparison between NTSC(National Time service Conter,the Chinese Academy of Sciences)and CRL(Communications Research Laborntory,which has been renamed National Institute of Information and Communications Technology)are presented.
