【摘要】：提出了北斗地基增强系统(Ground-based Augmentation Systems,GBAS)的着陆系统(GBAS Landing System,GLS)信号覆盖评估方法,从卫星对地覆盖及甚高频数据广播电台(VHF Data Broadcast,VDB)信号覆盖两方面进行评估.卫星对地覆盖评估中首先利用网格点分析法和视函数法评估卫星对地覆盖重数及4个覆盖性能指标:覆盖百分比、最大覆盖间隙、平均覆盖间隙及时间平均间隙,然后从用户角度分析卫星覆盖问题(卫星可见性).VDB信号覆盖评估中,对电磁波传播过程综合考虑了地球曲率及地形影响.另外,综合考虑目标机场的卫星可见性及VDB信号覆盖范围,结合美国联邦航空管理局规定的VDB信号最小覆盖空域,给出了本文评估方法在VDB选址中的应用.仿真结果表明该方法可以合理确定北斗GLS信号的覆盖情况及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.
