5 Equipment in TF lab Cesium atomic clock 5071A Pulse distribution unit /TIMETECH/ Frequency distribution and Amplifier /TIMETECH/ Universal time interval counter /Agilent / GNSS receiver GTR51 /DiCOM / Lantime Meinberg M600 for NTPserver Rubidium frequency standards FS725 GPS controlled Rb frequency standard R-12 Single channel GPS -JRC-NCR12 * isntalled under the Czech Rep project. In in 2014 became contributing to UTC TAI

6 GNSS antenna GTR51 Data logger, Linux System 10 MHz 1 PPS No reference delay No 1 PPS calble delay Frequency Distribution Amplitude Pulse Distribution Unit LANTIME NTP INTERNET

7 Data example CGGTTS ( UTC-MASM) INT Delay and REF Delays are not measured

8 UTC(MASM) in latest Circular T

9 Outline of TF lab 1 st floor of MASM Frequency Distribution Amplitude Pulse Distribution Unit GTR51 NTP Office room NEW INVERTER WAS PURCHASED FOR POWER BACK UP in early 2017 Base floor

10 We were informed about BIPM calibration campaign via Dr Liang Kun from BIPM BUT Travelling calibrator weight 102 kg so transportation fee would high accordantly, around 1400 US$ Tentative schedule route was as Calibration plan of GNSS receiver NIM MASM HKO SCL NIM Our suggestion for schedule - route NIM SCL HKO MASM NIM Expected in 2018 if this schedule is approved

11 Time dissemination Network Time Service MASM operates public NTP server referenced to UTC(MASM) in free access. Host name: ntp.mn Dissemination signal inaccuracy is less than 0.03 ms Cs atomic clock master.icttime.mn Meinberg Lantime M600 /master/ slave. ntp.mn ntp.mn Meinberg Lantime M300 MASM NATIONAL DATA CENTRE

12 DEMANDS from customers Calibration of GNSS/ GPS receivers in real time kinematic (RTK) from geodetic and mining companies / 1st order height networking is planned where more than 250 such receivers used, reliable results needed / Calibration of high accuracy frequency oscilloscopes, time interval counters used in telecommunication broadcasting companies Taximeter simulator, radar equipment for measurement of speed of vehicles /Legal metrology purpose/

13 Future plan: Maintenance of continuous data submission to UTC TAI upgrade UPS, Make use of data PPP processing for geodetic purposes Implement of alternative ways of time dissemination Calibration of GRT 51- receiver calibration via APMP G2 link as to improve uncertainty of UTC(MASM) Participate in future ILC, preparation of CMC Attend the future training as to fulfil the customer s demands, specially in calibration of frequency counter, GPS receivers, time interval counters.

14 PROPOSAL TO MEDEA 2.0: On site expert visit to get more practical knowledge and know-how, consult on solving problems faced in real situation Formal training among APMP TTCF members on calibration of frequency generating/measuring instruments and oscilloscopes and its uncertainty evaluation Support participation of contributing labs in future ILC
