“北斗区域导航系统”非精密进近导航性能分析
Performance Analysis for BeiDou Regional Navigation Satellite System of NPA
摘要
Abstract
A prospective research for using the BeiDou Regional Navigation Satellite System to civil aviation application w as made based on the characteristics of “5GEO+5IGSO+4M EO”constellation and requirements of non‐precise approach (NPA ) in civil aviation . For three indexes the visibility of space vehicle , dilution of precision (DOP ) values and horizontal protection level (HPL ) value , the statistical characteristics in Asia‐Pacific area and the comparison of three indexes for 4 designated user locations were presented by simulation and analysis . The results show that the BeiDou Regional Navigation Satellite System has the ability to provide the ideal number of satellite in sight , better values of DOP and HPL , and can meet the current needs of the above three indexes in NPA flight phase .关键词
