RMS from the mean value of the reference signal of frequency 1 \u0420\u0420S of the slave server of the communication center (Kyiv) when transmitting reference signals for synchronizing time from the reference standard of the units of time and frequency of the Armed Forces of Ukraine (Kharkiv) in the observation interval of 30 days (with periodic daily switching on the servers located in the ICEC of the Armed Forces of Ukraine) did not exceed 100&nbsp;ns. With a continuous operating mode (2 days), the RMS was not more than 65&nbsp;ns.The research results make it possible to formulate basic requirements for the composition, technical characteristics, functional capabilities and operating modes of the equipment of the military consumer time synchronization system using the PTP and NTP protocols over packet data networks \u2013 Ethernet in order to ensure its reliability and accuracy.<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/31.202.14.121\/wp-content\/uploads\/2024\/12\/204255-Article-Text-458320-1-10-20200528.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"\u0412\u0441\u0442\u0430\u0432\u043a\u0430 204255-Article Text-458320-1-10-20200528\"><\/object><a id=\"wp-block-file--media-16fcfe64-9618-4e3a-b800-f89fd23d58a6\" href=\"https:\/\/31.202.14.121\/wp-content\/uploads\/2024\/12\/204255-Article-Text-458320-1-10-20200528.pdf\">204255-Article Text-458320-1-10-20200528<\/a><a href=\"https:\/\/31.202.14.121\/wp-content\/uploads\/2024\/12\/204255-Article-Text-458320-1-10-20200528.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-16fcfe64-9618-4e3a-b800-f89fd23d58a6\">\u0417\u0430\u0432\u0430\u043d\u0442\u0430\u0436\u0438\u0442\u0438<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Abstract As part of the operation of the military segment of the Service of Universal Time and Reference Frequencies, the results of the pilot operation of the subsystem for providing universal time for military consumers are presented, which is built on the basis of the national measurement standard of time and frequency, the output standard [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-121","post","type-post","status-publish","format-standard","hentry","category-1"],"_links":{"self":[{"href":"https:\/\/www.qrngua.website\/index.php?rest_route=\/wp\/v2\/posts\/121","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qrngua.website\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.qrngua.website\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.qrngua.website\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.qrngua.website\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=121"}],"version-history":[{"count":1,"href":"https:\/\/www.qrngua.website\/index.php?rest_route=\/wp\/v2\/posts\/121\/revisions"}],"predecessor-version":[{"id":123,"href":"https:\/\/www.qrngua.website\/index.php?rest_route=\/wp\/v2\/posts\/121\/revisions\/123"}],"wp:attachment":[{"href":"https:\/\/www.qrngua.website\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=121"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.qrngua.website\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=121"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.qrngua.website\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
