(1) Coordinated Universal Time (UTC) is the international reference time scale that forms the basis for the coordinated dissemination of standard frequencies and time signals.
(2) GNSS common view is the time
transfer method used most frequently for comparing time scales. In GNSS common view, two users with known positions simultaneously observe the same satellites and calculate their respective time offsets from the satellite clocks.
(3) Time scale systems have traditionally been reserved for scientific measurements performed by metrology labs. However, with the global threat of GNSS vulnerability on the rise, the role of a country’s national time scale is changing from being just a scientific measurement to becoming a vital part of a country’s critical infrastructure.
(4) The Precise Time Scale System (PTSS) has a highly robust and resilient architecture that provides UTC class time—UTC(k)—to serve as the primary time source for a country.
(5) Using values published by the BIPM [UTC – UTC(k)],
the time scale can be steered so that its locally generated time aligns with UTC.
(7) The Bureau International des Poids et Mesures (BIPM) is an international organization located in France that is responsible for establishing and distributing the UTC time scale and working with laboratories around the world that help contribute to UTC. The BIPM offers a monthly publication that provides the values of the differences [UTC – UTC(k)] for institutes across the globe.
(6) A local/physical realization of UTC is referred to as UTC(k) where the letter “k” represents the laboratory, such as a metrology institute or other authoritative agency.
