廣電領域：時鐘系統(tǒng)主要是為全臺提供統(tǒng)一的時鐘信號源，保證播控室機房、演播室機房以及各子系統(tǒng)保持統(tǒng)一時間，同時也為現(xiàn)場工作人員提供準確時間信息，亦可遠程為轉播車內(nèi)系統(tǒng)提供校時時間。 </p> <p> 教育領域：時鐘系統(tǒng)主要功能是向在教學樓、實驗樓、后勤樓等的教職工、學生和工作人員提供準確的時間信息，同時也為自動化設備、智能化網(wǎng)絡與辦公系統(tǒng)提供安全、標準、統(tǒng)一的時間源。使各部門的工作井然有序、協(xié)調(diào)一致，各工作和教學環(huán)節(jié)密切配合，確保各業(yè)務高速有序精確運行。時鐘系統(tǒng)的安全性與準確性，為各事件的發(fā)生提供了時間追溯依據(jù)，是教學活動和考試組織等的基礎。 </p> <p> 金融領域：數(shù)據(jù)中心的大部分服務器都有自己的本地時鐘，獲取網(wǎng)絡時間源信號。由于網(wǎng)絡傳輸?shù)穆酚商匦裕W(wǎng)絡時間信號源的精度不高，不同服務器的時間會有細小差別。時鐘系統(tǒng)可以為所有服務器以及監(jiān)控等終端設備提供準確、統(tǒng)一的時間，保證各業(yè)務的有序進行，以及數(shù)據(jù)中心內(nèi)部安全性。 </p> <p> 機場領域：時鐘系統(tǒng)可以為進/出港旅客及機場工作人員提供準確的時間服務，同時為計算機系統(tǒng)及其他弱電子系統(tǒng)提供同一、準確的時間源。確保整個機場系統(tǒng)運行的準時、安全。 </p> </p> <p> <br />

隨著科學技術的進步，時頻已經(jīng)發(fā)展成為信息技術的重要支撐技術之一，在**科技領域、國民經(jīng)濟建設和社會生活中具有舉足輕重的作用。時頻產(chǎn)品主要分為兩大類：頻率產(chǎn)品、時間同步產(chǎn)品。兩者的區(qū)別在于：頻率系列產(chǎn)品產(chǎn)生具有穩(wěn)定頻率的信號，某種程度上也可以看作是頻率源，一般可以看作基準信號；而時間同步產(chǎn)品，則是時間同步算法以電路的形式實現(xiàn)，根據(jù)基準信號，去校準時間。 </p> <p> 頻率產(chǎn)品以原子鐘和晶體器件為** 產(chǎn)生穩(wěn)定的頻率信號，頻率組件及設備對頻率信號進行合成、變換、濾波及放大等處理，產(chǎn)生和輸出電子系統(tǒng)所需的各類頻率信號，擴展了頻率覆蓋范圍。時間同步產(chǎn)品采用原子鐘或高穩(wěn)晶振作為頻率源，產(chǎn)品類型包括板卡、模塊、設備及系統(tǒng)，時頻板卡及模塊可嵌入各用戶設備和系統(tǒng)中，并與時間同步設備共同組成時間同步系統(tǒng)。 </p><p style="text-indent:25px"> 精確的授時系統(tǒng)對一個國家而言具有非常重要的意義?，F(xiàn)有的授時系統(tǒng)一般采用衛(wèi)星授時系統(tǒng)（例如GPS/北斗）。目前美國、俄羅斯等國都在研究新的授時技術，以便擺脫對衛(wèi)星授時系統(tǒng)的依賴。2013年2月23日，我國GWY頒布的國發(fā)〔2013〕8號文件《國家重大科技基礎設施建設中長期規(guī)劃（2012-2030年）》，明確提出支持超精密時間頻率技術開發(fā)，適時啟動高精度地基授時系統(tǒng)的建設，明確將高精度地基授時系統(tǒng)的建設提到了與北斗衛(wèi)星授時系統(tǒng)同等重要的戰(zhàn)略高度。2016年2月19日，科技部發(fā)布的“國家質量基礎的共性技術研究與應用”重點專項中，明確將“時間頻率基準及其傳遞技術研究”列入了國家重點研發(fā)計劃（2016～2020年******），“研究長距離時間頻率光纖傳遞技術”是其中的一個重要的研究方向。公司也是全國電力系統(tǒng)WAMS及時間同步工作組標委會成員單位，參與國家及行業(yè)標準制定數(shù)十項。</p><div

style="text-indent:25px">時間同步的另一種方法是用無線電波傳播時間信息。即利用無線電波來傳遞時間標準．然后由授時型接收機恢復時號與本地鐘相應時號比對，扣除它在傳播路徑上的時延及各種誤差因素的影響，實現(xiàn)鐘的同步。隨著對時鐘同步精度要求的不斷提高，用無線電波授時的方法，開始用短波授時（ms級精度），由于短波傳播路徑受電離層變化的影響，天波有一次和多次天波，地波傳播距離近，使授時精度*能達到ms級。后來發(fā)展到用超長波即用奧米伽臺授時，其授時精度約10μs左右，后來又用長波即用羅蘭C臺鏈兼顧授時，其授時精度可達到μs，即使羅蘭C臺鏈組網(wǎng)也難于做到全球覆蓋。后來又發(fā)展到用衛(wèi)星鐘作搬鐘。用超短波傳播時號．通過用戶接收共視某顆衛(wèi)星，使其授時精度優(yōu)于搬鐘可達到10ns精度?？磥砝眯l(wèi)星授時是實現(xiàn)全球范圍時鐘精密同步的好辦法，只有利用衛(wèi)星，才可在全球范圍內(nèi)用超短波傳播時號；用超短波傳播時號不*傳遞精度高，而且可提高時鐘比對精度，通過共視方法，把衛(wèi)星鐘當作搬運鐘使用，且能使授時精度高于直接搬鐘，直接搬鐘難于使兩地時鐘去共視它。共視可以消除很多系統(tǒng)誤差以及隨時間慢變化的誤差，快變化的隨機誤差可通過積累平滑消除。公司生產(chǎn)的時鐘同步設備CT-TSS4200具備授時、監(jiān)測、管理功能，產(chǎn)品經(jīng)過國家電網(wǎng)檢測中心檢測通過。四川高精度高穩(wěn)定高可靠衛(wèi)星授時設備/裝置價格優(yōu)惠</p><p
