IMPROVEMENT OF THE ACCURACY OF THE ATOMIC TIME-SCALE AT COMMUNICATIONS-RESEARCH-LABORATORY

We show the results of computer simulations of the time scale generate d by the atomic time (TA) algorithm, using data obtained from an ensem ble of clocks at Communications Research Laboratory (CRL). Three accur acy evaluations were made using the laboratory type primary frequency standard (CRL Cs1) over the period between February, 1989 and January, 1992. Our results show that the accuracy of the TA(CRL) time scale ra te is increased by more than 5-6 times when using the clock data calib rated by the primary frequency standard.
