Frequency Standard provides VCXO output frequency stabilization to the high stability atomic transition line in\u00a0<sup>87<\/sup>Rb alkali metal isotope vapours.<\/p>\n<p>The Instrument is based on the unique electrovacuum technology connected with physical and chemical processes of gaseous medium and alkali metal isotope interaction with an electromagnetic field.<\/p>\n<p>The Standard metrological characteristics are superior to the best Crystal Oscillator characteristics.<\/p>\n<p><strong>APPLICATIONS<\/strong><\/p>\n<p>The Standard high metrological characteristics define its wide<strong>\u00a0<\/strong>application range:<\/p>\n<ul>\n<li>Radionavigation systems;<\/li>\n<li>Ground and satellite communication systems;<\/li>\n<li>Chronometry systems.<\/li>\n<\/ul>\n<p>Environmental resistance, small size, weight and low power consumption allow this Standard to be used in different mobile systems and complexes.<\/p>\n<p>The Standard
