Automatic dependent surveillance ( ads ) system trial for route r214 航路r214的自動(dòng)從屬監(jiān)察測(cè)試
Adopting the automatic dependent surveillance ( ads ) method , we have ensured the flight safety , enhanced the capacity of flight , met the need of increase of civil aviation 采用自動(dòng)相關(guān)監(jiān)視,保證了飛行安全,提高了飛行容量,滿足了未來(lái)航空增長(zhǎng)的需要。
Now with the emergence of improved air - ground data communication technologies such as aircraft communication addressing and reporting system acars , automatic dependent surveillance and secondary surveillance radar mode s , the opportunity is there for aircraft reporting by fully automatic means 由于空中對(duì)地面的通訊技術(shù)的革新,例如飛機(jī)通訊通話及報(bào)告系統(tǒng)acars自動(dòng)從屬監(jiān)視系統(tǒng)ads及二次監(jiān)察雷達(dá)ssr s模式的出現(xiàn),均能促進(jìn)飛機(jī)自動(dòng)化提供天氣報(bào)告。
Vdl mode 4 is consulted the data link layer of osi reference model , and it provides upper layers with reliable point - to - point connection . because of the particularity of the civil aviation ' s applications , vdl - 4 protocol will support some special application program directly , such as automatic dependent surveillance - broadcast ( ads - b ) 在對(duì)協(xié)議進(jìn)行研究的基礎(chǔ)上,本文實(shí)現(xiàn)了與廣播式自動(dòng)相關(guān)監(jiān)視( ads - b )應(yīng)用相關(guān)的vdl - 4協(xié)議棧的vss子層和lme子層,其中主要包括預(yù)約機(jī)制、網(wǎng)絡(luò)接入和同步數(shù)據(jù)幀的廣播等。
Now with the emergence of improved air - ground data communication technologies such as aircraft communication addressing and reporting system ( acars ) , automatic dependent surveillance ( ads ) and secondary surveillance radar ( ssr ) mode s , the opportunity is there for aircraft reporting by fully automatic means 由于空中對(duì)地面的通訊技術(shù)的革新,例如飛機(jī)通訊通話及報(bào)告系統(tǒng)( acars ) 、自動(dòng)從屬監(jiān)視系統(tǒng)( ads )及二次監(jiān)察雷達(dá)( ssr ) s模式的出現(xiàn),均能促進(jìn)飛機(jī)自動(dòng)化提供天氣報(bào)告。
