BIH Report

Abstract

Before describing the BIH activities on the atomic time scales, I will present the new administrative organization which will be effective from 1988 January 1. This re-organization has its roots in an unsatisfactory decision taken at the end of World War I : a short history of the BIH since its conception in 1919 until the splitting in two different services in 1988 will help in the understanding of a necessary evolution. The 13th current activity of producing the International Atomic Time TAI and the Universal Coordinated Time UTC has been regularly pursued and considerably improved by the availability of the time comparisons using the GPS. In addition, with an improved statute and an increased staff, we were able to undertake experimental tasks in order to reduce the biases of the time comparisons and we plan to intensify this effort. We will give an overall view of the present performances of TAI and also, by comparison with some national time scales, show some achievements and problems in the realization of time scales.
