ABSTRACT
The necessity of constant modernization of quantum frequency standards (QFS) - atomic clocks, which are used in satellite navigation and telecommunication systems to solve new problems in the transmission rate of large amounts of information, etc. It is noted that among all atomic clocks, cesium QFS occupy a special place. These standards are the primary frequency reference on which the international time scale is based. The main goal of all upgrades of the QFS is to improve the metrological characteristics. In the case of its application on mobile objects, its dimensions, weight and energy consumption also become important characteristics. The article presents one of the options for reducing the influence of negative factors on the stability of the QFS. The development of a device for stabilizing the magnitude of the magnetic field at a given level in the QFS atomic-beam tube is proposed. Her work is modeled. A prototype has been made. The results of studies of the operation of the QFS with a new stabilizer of the magnetic field in the atomic-beam tube are presented. It is found that the short-term stability of the frequency of the output signal of the frequency standard is improved by 10%, which makes it possible to improve the synchronization of the time scales.

ISPAN '09: Proceedings of the 2009 10th International Symposium on Pervasive Systems, Algorithms, and NetworksSince WSNs have restricted energy sources, the energy efficiency of a synchronization scheme is as important as the accuracy of a clock. To accomplish both the energy efficiency and the accuracy, we propose a new clock synchronization scheme called ...
