        <p>The necessity of modernization of quantum frequency standards (QFS), atomic clocks, which are used in satellite navigation and telecommunication systems, is substantiated. The main goal of all QSC upgrades is to improve the metrological characteristics. In the case of its use on moving objects, its dimensions, weight and power consumption also become important characteristics. The new developed optic system has been applied to low mass ion
clock prototype. With its help it has become possible to significantly take up short term stability and temperature coefficients. The prospects for using this design in various moving objects are considered.</p>
