  1. BSJ National Time Realization

  2. Background • The Bureau of Standards, Jamaica embarked on a Time and Frequency Program • Its aim was to establish a national Time Scale i.e. (our own local time) with traceability to UTC • Contribute to BIPM hence the calculation of UTC • The Bureau began procuring equipments to realize this project. • Bureau also embarked on Town Clock project

  3. Objectives • To make time a legal metrology quantity and thereby be able to create and disseminate local time to users of Time and Frequency, this will include; • Drafting of regulations to make time a legal metrology quantity. • An amendment to the Weights and Measurements Act to create legal time. • To establish a calibration lab capable of disseminating time and frequency measurement traceable to the SI. This will entails; • Establishing the local time scale and traceability to the SI through BIPM • As a SIM member, BSJ Jamaica was invited to participate in SIM Time and Frequency working group. …cont

  4. Objectives …cont • To establish time and frequency services from which revenue can be earned. • Establishment of a Network Time Service • Establishment of a voice time Service • Calibration Service (Time and Frequency based devices e.g. Stopwatches, timers, counters, tachometers, Signal Generators)

  5. Objectives …cont • Provide a platform from which other areas (Especially AC/DC and Dimensional Metrology, Energy Metrology) can provide future services.

  6. Objectives • To implement a state-of-the-art timekeeping and time dissemination Lab that has the capability to support user needs and also remain ahead of their future needs. • Maintaining traceability to other timing labs and to International Atomic Time. • To be recognized as a productive member of the world timekeeping community.

  7. Equipments • Cesium 4065 Symmetricum • CsIII Standard • Three (3) counters • Two (2) Fluke PM6690 (Acquired in 2008) • One (1) Fluke PM6681 • TTS-2 System • SIM • Frequency Distribution Amplifier.

  8. Future Plans • Training of Personnel • Acquire Equipments to expand the capability of the lab, monitor standards and distribute time. • Phase Comparator system/Software • Network Time Server • Additional Clock • Distribution amplifiers • Function Signal Generator

  9. Proposed system BSJTime and Frequency Lab
