摘要
According to TWSTFT, two way optical fiber time and frequency transfer(TWOTFT) was designed.TWOTFT in real time based on the instant exchange of time transfer data via optical fiber was implemented. One kind of time and frequency standard disciplined by UTC(NIM) (National Metrology Primary Standard of China), called NIMDO, was constructed using TWOTFT for accurate and precise time synchronization, whose time difference from UTC(NIM) could be less than 1 ns, which is much better than NIMDO via GNSS (Global Navigation Satellite System) time transfer method (based on GPS (Global Positioning System) time transfer).
