NIMT time and frequency keeping NIMT operates three caesium atomic clocks with high performance tube, 5071A with Option 001 UTC(NIMT) is generated from the high performance caesium clock and HROG-5 Dual frequency multi-channel GPS receiver (Topcon) Single frequency multi-channel GPS receiver (Oncore)

Time and Frequency dissemination ● Calibration services In laboratory calibration (Rb, Qrtz, Freq. Counter) Remote calibration (Timetrace GPSCV) for GPSDO ● Time synchronization through Internet(3 NTP servers) ● speaking clock operated by Navy ● Time synchronization through public telephone ● Time distribution through FM/RDS transmitter (40 provinces)

Display clocks developed in Thailand RDS RDS and NTP

Telephone standard time transmitter Telephone clock
