【摘要】：提出了北斗地基增強(qiáng)系統(tǒng)(Ground-based Augmentation Systems,GBAS)的著陸系統(tǒng)(GBAS Landing System,GLS)信號(hào)覆蓋評(píng)估方法,從衛(wèi)星對(duì)地覆蓋及甚高頻數(shù)據(jù)廣播電臺(tái)(VHF Data Broadcast,VDB)信號(hào)覆蓋兩方面進(jìn)行評(píng)估.衛(wèi)星對(duì)地覆蓋評(píng)估中首先利用網(wǎng)格點(diǎn)分析法和視函數(shù)法評(píng)估衛(wèi)星對(duì)地覆蓋重?cái)?shù)及4個(gè)覆蓋性能指標(biāo):覆蓋百分比、最大覆蓋間隙、平均覆蓋間隙及時(shí)間平均間隙,然后從用戶角度分析衛(wèi)星覆蓋問(wèn)題(衛(wèi)星可見(jiàn)性).VDB信號(hào)覆蓋評(píng)估中,對(duì)電磁波傳播過(guò)程綜合考慮了地球曲率及地形影響.另外,綜合考慮目標(biāo)機(jī)場(chǎng)的衛(wèi)星可見(jiàn)性及VDB信號(hào)覆蓋范圍,結(jié)合美國(guó)聯(lián)邦航空管理局規(guī)定的VDB信號(hào)最小覆蓋空域,給出了本文評(píng)估方法在VDB選址中的應(yīng)用.仿真結(jié)果表明該方法可以合理確定北斗GLS信號(hào)的覆蓋情況及VDB位置.
[Abstract]:The compass ground-based augmentation system (Ground-based Augmentation Systems, GBAS) of the landing system (GBAS Landing System, GLS) signal coverage evaluation method, from the satellite coverage and VHF data radio (VHF Data, Broadcast, VDB) signal covering two aspects of evaluation. A satellite coverage assessment using grid point analysis method and visual function evaluation of satellite coverage multiplicity and 4 coverage performance: coverage percentage, maximum coverage gap, the average coverage gap and average time gap, and then analyze the satellite from the user point covering problem (satellite visibility).VDB signal coverage evaluation, considering the curvature of the earth and the influence of terrain on electromagnetic wave the process of communication. In addition, considering the target airport satellite visibility and VDB signal coverage, with minimum VDB signal coverage airspace FAA regulations, The application of this method in the VDB site selection is given. The simulation results show that the method can reasonably determine the coverage of the Beidou GLS signal and the location of the VDB.
