摘要(Abstract)：

IGS14地球参考框架发布后,IGS分析中心参考框架已从IGS08转到IGS14,研究框架变化对精密定轨影响变得尤为迫切和重要。为了验证参考框架更新对精密定轨的的影响,该文采用不同的参考框架进行全球定位系统(GPS)精密定轨,并将定轨结果与国际GNSS服务(IGS)分析中心的轨道产品进行对比。实验结果表明,对于GPS卫星,轨道与IGS精密轨道互差均值从32.83 mm变为29.1 mm,重叠弧段均值从29.5 mm变为26.9 mm,更新参考框架后GPS的定轨结果得到提高。相较于IGS08地球参考框架,IGS14地球参考框架在测站位置速度精度、站点震后形变效应的影响和周年半年误差信号等处理上,更加接近测站实际的运动变化过程,有助于提高精密定轨的精度。
