（1）由于歷史的原因,我國目前的電力行業(yè)的時間同步系統(tǒng)的時鐘源大都采用米國GPS系統(tǒng)做為主時鐘源。目前，GPS是米國軍方控制的軍民共用的系統(tǒng)，對全世界開放。我國目前使用的GPS屬于**接收的米國信號。盡管如此，但是米國人并不承諾保證你的使用。這樣就帶來一個安全問題, 如涉及**系統(tǒng)以米國的GPS作為主時鐘源，這便存在著重大的安全隱患，一旦發(fā)生ZhanZheng等緊急事態(tài)，米國關(guān)閉或調(diào)整GPS信號，將給我們的安全帶來很大影響。（2）如何建立完善的時間同步機制,同時使各安全系統(tǒng)時間同步系統(tǒng)不受他國控制,是擺在國家面前的一大課題?北斗時鐘同步裝置就是在這種情況下應(yīng)運而生的，四川***高性價比時間同步設(shè)備裝置/系統(tǒng)服務(wù)保障，為了保障我國各行業(yè)系統(tǒng)的生產(chǎn)、運行安全，四川***高性價比時間同步設(shè)備裝置/系統(tǒng)服務(wù)保障，北斗雙模時鐘同步裝置同時接收GPS和北斗兩個不同衛(wèi)星系統(tǒng)的標準時間信息，當其中一個系統(tǒng)接收故障或者信號異常時，可以自動切換到另外一個另外一個授時系統(tǒng)，保證上游時間源的穩(wěn)定接收，由于北斗衛(wèi)星導航定位系統(tǒng)是由我國自主開發(fā)的，相對于GPS系統(tǒng)來說，在安全性上也更有保障，四川***高性價比時間同步設(shè)備裝置/系統(tǒng)服務(wù)保障。實現(xiàn)北斗二代/GPS 雙模高精度授時系統(tǒng)，支持對多時間源實時監(jiān)測及無擾動切換，提供多類標準接口授時模式。四川***高性價比時間同步設(shè)備裝置/系統(tǒng)服務(wù)保障</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
