摘要:

深入解析了基于码伪距测量的卫星双向时间频率传递(TWSTFT)原理,对其误差进行了分析,其精度主要受码速率的限制,难于满足更高精度要求;文章提出了基于载波相位的卫星双向时间频率传递方法,载波频率高,波长短,从理论上分析了以其作为TWSTFT伪距测量的参数可大幅度提高时间传递的精度;并对TWSTFT载波相位测量存在的误差源进行了初步分析,得出影响最大的因素是转发器误差、电离层误差、多径效应误差及星站相对运动引起的误差,参考GPS载波相位测量中误差消除的方法,对误差的消除方法提出建议。

关键词: 卫星双向, 载波相位, 误差分析

Abstract:

TWSTFT theory based on the code pseudo-ranging and the error in which is analyzed. For the code rate limited, the precision of the system is difficult to be promoted. So, the TWSTFT based on the carrier-phase measuring is presented, which can enhance the precision more for the high frequency and short wave of the carrier. And the error source in the carrier-phase measuring TWSTFT is analyzed in the paper, result shows that the major source is the errors caused by ionosphere, transponder, and the relative moving between the earth station and satellite.

Key words: TWSTFT, carrier-phase, error analysis.
