    時頻技術服務現代戰爭      

    在時間以小數秒計量和計劃的信息時代,準確時間和時間統一對于贏得現代戰爭勝利的重要性是是不言而喻的。無論是全軍聯合作戰指揮、全軍通信保障、武器平臺作戰、武器試驗、網絡信息化、海空軍敵我識別,以及軍用通信網/偵察網/預警雷達網、多兵種武器協同作戰、時間頻率計量測試等等,都離不開北斗系統授時支持。北斗系統已成為建設信息化軍隊、打贏信息化戰爭的重要基礎和保證,已成為軍事戰斗力的有機組成部分和作戰效能倍增器。


    時頻技術保障通訊組網安全      

            

    我國的頻率同步網采用的是多基準混合同步方式,即全網部署多個1級基準時鐘設備,并且需配置高性能的衛星授時接收機,以保證全網的定時性能,在每個時間同步設備上均需配置高性能的衛星授時接收機,以保證全網的時間精度。

    就移動通信網絡而言,無線通訊基站等均需要高精度的時間同步,目前是在每個基站上配置GPS授時模塊。如果基站與基站之間的時間同步不能達到一定要求,將可能導致在選擇器中發生指令不匹配,從而導致通話連接不能正常建立,影響無線業務的接續質量。

    在通信網絡中使用自主的北斗衛星授時接收機/模塊,將根本解決因大量使用GPS授時而導致的全網同步運行及業務網絡組網的安全性問題。

    從通信領域中北斗授時應用需求及前景來看,北斗二代授時產品在應用場景和抗干擾能力方面也優于北斗一號,北斗二代產品完全可以與GPS產品相抗爭。尤其對于一些重要的通信領域,北斗授時的應用將全面提升網絡的安全性,相對于采用其他國家衛星導航系統,這種優勢不可替代。

    從各方面來看,北斗系統完全可以滿足國內通信網對時頻基準信號高性能高可靠性的要求,加快推動北斗授時在通信領域的應用已經勢在必行。
