  8. " the atis and volmet systems installed at the hong kong international airport ( hkia ) have been upgraded with datalink capability and dedicated digital communication links have been set up with the sita aircom service to enable airlines to access hong kong atis and volmet service via both very high frequency ( vhf ) and satellite datalink, " he said

    在香港國際機場裝置的自動航站情報和遠航氣象情報系統已加添數據鏈路應用功能，而專用的數據化通訊連接網路亦已透過國際航空電訊公司提供，讓航空公司能利用高頻通訊或衛星數據鏈路，獲取香港自動航站情報服務和遠航氣象情報服務。
  9. Frequency - hopping ( fh ) is a novel spread spectrum communication technique, which develops very fast in military field due to its lpi / lpd ( low probability of intercept / detection ) properties and immunity against interferences, the extensive application of hf / vhf ( high frequency / very high frequency ) frequency - hopping radios in military has greatly enhanced the ability of military equipments against jamming and interception and ensure the safety and validity of chain of military command

    跳頻技術是擴頻技術的一種，是80年代以來出現的一種新的通信方式。跳頻通信具有良好的抗干擾性，低截獲概率及組網能力，因此跳頻技術的一出現，便在軍事領域得到了極大的發展。採用跳頻技術的短波超短波電臺在軍事通信中得到了廣泛應用，極大地提高了軍事裝備的抗截獲和抗干擾能力，保證了軍事指揮系統的安全和有效性。
  10. In the communication system of cns / atm, vhf data communication is used in busy air space, and aeronautical mobile - satellite service ( amss ) is used in other air spaces, such as ocean and desert, but can improve the flight safety greatly in the navigation system of the cns / atm, global navigation satellite system ( gnss ) is the main elements

    在新航行的通信系統中，主要發展數據通信， vhf通信用在繁忙的空域， amss主要用在海洋、荒漠空域，但都能極大地提高飛行安全。
  11. During the last century, the vhf ( very high frequency ) communication has been applied in the ship ' s transportation, as well as radar and arpa also could identify ships in the marine. but they could n ' t adapt to the needs of the modern navigation because of their limits. the rapid development of the digital communications technology, computer technology and net ware technology supports the needed technology of ais ( automatic identification system )

    上個世紀， vhf通信技術被廣泛地應用於船舶通信；雷達、 arpa具有識別船舶的功能，但是由於自身的局限性而無法適應現代航運安全的需求；隨著數字通信技術、計算機技術以及網路信息技術的飛速發展， ais的技術基礎已經搭建好，在航運界對助航設備的要求越來越高的情況下，船舶自動識別系統應運而生。
