Abstract:

Since the early years of this decade, the set of Polish metrology and science laboratories have been organized in a group for the local independent ensemble atomic timescale TA PL. From the beginning, Lithuania SPI has participated in the calculations. This year, the laboratory in Latvia LNMC also joined our group. The number of standards which form our timescale have changed from 7 to about 15. In 2004, the National Institute of Telecommunications started a project to develop a Database for TA PL and UTC PL. The goal was to reduce the time of waiting for results of comparisons of clocks which was necessary to control time and frequency. In the beginning, the time delay was about 1.5 months. This document presents elements of the automated system developed to process the results of clock comparisons and to compute the ensemble timescale. First, it shows the general work flow scheme. The next part presents the ensemble timescale based on implemented algorithms ALGOS, AT1 and useful functions built in to provide control over clocks. The last part contains a short description of functions planned for future development.
