SIM time scales



Michael A. Lombardi, J. Mauricio Lopez-Romero, Nelida Diaz-Munoz


This paper presents an analysis of the performance of some of the time scales generated in the Sistema Interamericano de Metrologia (SIM) region. We emphasize the generation of the first international time scale in near real time, the SIM Time scale (SIMT). The SIMT can be used as a reference to evaluate the performance of the time scales of the region taking advantage on the fact that values of the SIMT are disseminated through the web site of the SIM Time and Frequecy Metrology Working Group in real time.
