Lithuanian National Time and Frequency Standard

Authors: Rimantas Miskinis; SEMICONDUCTOR PHYSICS INST VILNIUS (LITHUANIA)
Abstract:
The Lithuanian National Time and Frequency Standard Laboratory is responsible for maintenance and dissemination of the national time scale UTC (LT), time and frequency units. Since June 2001, we have been contributing to TAI. The Laboratory is equipped with two HP5071A cesium atomic clocks (one with a high-performance Cs tube) and two TTS-2 multichannel GPS receivers based on Motorola VP Oncore GPS processors. One of the GPS receivers is equipped with thermo-stabilized GPS antenna. For the dissemination of the Lithuanian Time Scale UTC (LT), the NTP server Datum 2001 is used. In this paper, the main metrological characteristics and technical possibilities of the National Time and Frequency Standards are presented.
