Disciplined oscillator system by UTC(NIM) for remote time and frequency traceability

Using GNSS time and frequency transfer receiver NIMTFGNSS-1, RTRC by GNSS code based time and frequency transfer has been realized. As the extension of RTRC, NIM can provide one low-cost Rubidium oscillator disciplined by UTC(NIM) in near real-time, NIMDO. Its performances have been verified and demonstrated at the two campuses of NIM. Referenced to UTC(NIM), we can acquired that the time and frequency accuracy of NIMDO could separately be better than 5 ns and 1e-13 averaging one day, and the time and frequency stability averaging one day could respectively be better than 5 ns and 6e-14.
