1 Time and Frequency Laboratory Measurement Units, Standards and Services Department (National Metrology Institute) MUSSD-Sri Lanka
2 Introduction Measurement Units, Standards and Services Department (MUSSD ) was established by Measurement Units, Standards and Services Act, No 35 of 1995 Regulation (related to T&F) 2011-Sri Lanka Standard time. MUSSD is empowered by Act in; Scientific Metrology Industrial Metrology Legal Metrology Research and consultancy of metrology related matters
3 International relations Associate member of CGPM Member of APMP Member of OIML Signatory of CIPM MRA, The CIPM MRA was signed on: 14 November 2007

7 Traceability of T&F Traceability with One-Way GPS Time and Frequency Measurements Using the Global Positioning System Michael A. Lombardi, Lisa M. Nelson, Andrew N. Novick, Victor S. Zhang National Institute of Standards and Technology Time and Frequency Division tycho.usno.navy.mil/gps_datafiles.html
8 Uncertainty 24h uncertainty is less than 5.0E-12 (In automatic logging and calculation in built to the instrument and Above agrees with manufacturer specifications, Adequate for current calibration services. (Stop watches, industrial process timers, Oscilloscopes, signal generators, tachometers other time related test instruments) (10 instruments per month)
9 T&F Staff Alanka Kuruppu Perera Wasantha
10 Activities for (Completed/ Planed) Purchasing equipment for establishment of national time scale (Cesium atomic clock, Multi channel dual frequency GNSS receiver, Pulse and Frequency distribution amplifiers and necessary accessories), This is necessary to go for accreditation ) Already call for bids, and received Offers for above equipments, Expect to establish a basic system consist of Cesium atomic clock, Multi channel dual frequency GNSS receiver, Pulse and Frequency distribution amplifiers in 2014 march. (Symmetricom 5071A, Septentrio Polar RX4TR PRO)
11 Demand for T&F in Sri Lanka Colombo stock exchange Media companies (TV, Radio) Transport sector (Train, Bus, Taxi) Communication companies Aviation industry
12 Activities for (Completed/ Planed) Proposed System for SL Standard Time (SLST) to be initiated in 2015 (Following other National laboratories setup)
13 Activities for year (Completed/ Planed) 2013-APMP Midyear meetings were hosted by MUSSD, Sri Lanka : Construction of new laboratory building with Instruments for development of existing technical capabilities and equipments for new fields with more staff.( Now the space is not enough for expanding laboratory services for necessary parameters to cover the needs of other institute requiring calibration services, legal metrology and industry )
14 Construction of New MUSSD Building Complex
15 Construction of New MUSSD Building Complex with Instrumentation and Personnel Location : near the city Homagama, about 20 km away from the Colombo City Total Estimated cost for the building: 2000 Million Rupees (Approx: 19 Million USD) Total estimated cost for instruments: 500 Million Rupees ( Approx: 4 Million USD) Planned to complete the laboratory area before 2014 November. Whole project planed to complete in next3 years ( end of 2016).
