| 摘 要： | 卫星双向法(TWSTFT)是目前比对精度最高的远距离时频传输技术,比对精度在0.3ns左右.本文介绍了TWSTFT的基本原理和中国计量科学研究院(NIM)卫星双向时间频率比对系统的构建情况.根据时间频率咨询委员会(CCTF)发布的卫星双向法软件标准化指南,对数据进行计算和处理,得到比对精度0.35ns.结合卫星双向法传输路径示意图,得出设备时延、电离层折射和卫星相对地面站运动为主要误差来源,其中设备时延引起的误差影响最大,为0.12ns.

| Abstract: | Two-way satellite time and frequency transfer(TWSTFT)is the most precise remote time transfer method.The comparison precision of TWSTFT could approximately reach 0.3ns.The basic principle and construction of TWSTFT in National Institute of Metrology(NIM)were demonstrated.When the data was processing,software standardization guide made by Consultative Committee for Time and Frequency was adopted and the comparison precision of NIM is about 0.35ns.According to the TWSTFT schematic diagram of transfer path,equ... |
