CONCEPTS OF SPACE-TIME AND MEASUREMENT UNITS| Session Chairs: | Yasuhiro Koyama, Parameswar Banerjee |
Time scale is one of the fundamental frameworks for scientific and engineering measurements. The current time scale is defined and maintained from the ensemble of a numerous numbers of atomic clocks and the quality of the time scale is continuously evolving. The key elements of the time scale are the algorithm of ensemble calculation, developments of better comparison techniques, developments of primary frequency standards, and so on. Papers describing various activities related with these elements are solicited.
