style="font-size:12px;">由于歷史的原因,我國(guó)目前的電力行業(yè)的時(shí)間同步系統(tǒng)的時(shí)鐘源大都采用米國(guó)GPS系統(tǒng)做為主時(shí)鐘源。目前，GPS是米國(guó)軍方控制的軍民共用的系統(tǒng)，對(duì)全世界開放。我國(guó)目前使用的GPS屬于**接收的米國(guó)信號(hào)。盡管如此，但是米國(guó)人并不承諾保證你的使用。這樣就帶來一個(gè)安全問題, 如涉及**系統(tǒng)以米國(guó)的GPS作為主時(shí)鐘源，這便存在著重大的安全隱患，一旦發(fā)生ZhanZheng等緊急事態(tài)，米國(guó)關(guān)閉或調(diào)整GPS信號(hào)，將給我們的安全帶來很大影響。</span> </p> <p> （2）如何建立完善的時(shí)間同步機(jī)制,同時(shí)使各安全系統(tǒng)時(shí)間同步系統(tǒng)不受他國(guó)控制,是擺在國(guó)家面前的一大課題?北斗時(shí)鐘同步裝置就是在這種情況下應(yīng)運(yùn)而生的，為了保障我國(guó)各行業(yè)系統(tǒng)的生產(chǎn)、運(yùn)行安全，北斗雙模時(shí)鐘同步裝置同時(shí)接收GPS和北斗兩個(gè)不同衛(wèi)星系統(tǒng)的標(biāo)準(zhǔn)時(shí)間信息，當(dāng)其中一個(gè)系統(tǒng)接收故障或者信號(hào)異常時(shí)，可以自動(dòng)切換到另外一個(gè)另外一個(gè)授時(shí)系統(tǒng)，保證上游時(shí)間源的穩(wěn)定接收，由于北斗衛(wèi)星導(dǎo)航定位系統(tǒng)是由我國(guó)自主開發(fā)的，相對(duì)于GPS系統(tǒng)來說，在安全性上也更有保障。四川**品質(zhì)衛(wèi)星授時(shí)設(shè)備/裝置推薦貨源廠家時(shí)頻產(chǎn)品為***信息化的**產(chǎn)品，所有信息化武器裝備系統(tǒng)都必須有高精度的頻率源作支撐。</p><div
