SASO time scale and measurement capability

Abstract

SASO Time and Frequency Laboratory is a responsible for national time scale generation and dissemination on Saudi Arabia. Recently at SASO NMCC the Time and Frequency Laboratory was developed using primary 5 Cs atomic clocks, 2 GNSS receivers and high technology modern equipments, The national time scale was generated with an uncertainty better than 2×10-14 and disseminated through the internet for industrial applications using an NTP time dissemination system with an uncertainty less than 50 ms. The fully automatic time and frequency calibration system that was developed is traceable to the national time scale and has the capability for frequency generation and measurement in the DC - 50 GHz range including signal analysis and phase noise measurements. Currently SASO is a member of BIPM Atomic Time Club in order to contribute to the Universal Coordinated Time (UTC) time scale and the realization of the international traceability of the SASO time scale.
