Publication Year: 2016,Page(s):1 - 5
The precision of two-way satellite time and frequency transfer (TWSTFT) is currently limited due to unstable measurement of the signal arrival time. To improve the TWSTFT precision without interrupting the main system, we introduce the software-defined receiver (SDR) to measure the arrival time of the code signal. The SDRs have been successfully installed among TL, NICT and KRISS, and time-differe...Show More
