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。 -
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。
