摘要

全球导航卫星系统时间传输广泛用于远程时钟比较，特别是BIPM用于UTC/TAI。用这种技术比较时钟需要校准GNSS接收链(在天线相位中心和参考时钟之间)。CNES多年来一直在GNSS接收链的绝对校准方面进行广泛的工作。本文介绍了CNES最近的改进和取得的结果。

Progress on absolute calibrations of GNSS reception chains at CNES

GNSS time transfer is widely used for remote clock comparisons, in particular by the BIPM for UTC/TAI. Comparing clocks with this technique requires a calibration of the GNSS reception chain (between the antenna phase center and the reference clock). CNES has been working extensively on the absolute calibration of GNSS reception chains for many years. This paper presents the recent improvements and results obtained at CNES.
