摘　　要：为分析基于北斗的陆基增强系统(Ground-Based Augmentation System,GBAS)在进近着陆阶段提供的导航性能,从地面、机载、空间三个层面仿真GBAS运行。在MATLAB环境下对广播星历数据进行处理,仿真北斗空间段星座和轨道运行情况。参考RTCA发布的GBAS最低运行性能标准,建立地面端和机载端数据模型,仿真增强算法。分析北斗系统的定位误差及导航性能。建立Simulink运动学和控制模型实现对姿态控制。研究Flight Gear输入/输出接口,实现与MATLAB联合仿真,并通过联合仿真方式,搭建应用北斗卫星导航系统的飞机进近着陆系统可视化仿真平台。In order to analyze the navigation performance of Ground-Based Augmentation System （GBAS） based on Beidou satellite navigation system （BDS） in approach and landing phase, segments of ground, airborne and space were simulated as GBAS. The broadcast ephemeris data was processed by MATLAB to simulate the BDS constellation and the orbit operation. Based on the minimum operational standards for GBAS released by RTCA, the data model of ground segment and airborne segment were established, and the enhancement algorithm was simulated to analyze the positioning error and navigation performance of BDS. Simulink kinematic and control models were developed to simulate the attitude of aircraft. FlightGear I/O interface was studied to realize the joint simulation with MATLAB, and visual simulation platform of aircraft approach and landing system for BDS was built by the joint simulation.
