摘　　要：为适应未来空中交通流量持续快速增长的需求,提高空管运行安全水平,提出一种将星基着陆系统GLS(global navigation satellite system landing system)和仪表着陆系统ILS(instrument landing system)两种进近程序融合使用的新方法,为着陆系统创造一个更经济和精密的进场体制。通过数学建模,将GLS进近数据和ILS进近数据等效在同一个直角坐标系中,仿真计算飞机进近航迹;并求出两种导航源分别与标准航迹的对比误差。仿真和实际验证试飞数据表明,基于GILS(GNSS landing system and instrument landing system)进近体制的组合进场策略可明显提高飞机进近过程导航精度和完好性水平,并提高进近速度,提高进近安全水平。现称该组合进场策略为GILS进场策略。In order to adapt to future demand for sustained and rapid growth of air traffic flow,to improve the level of safe operation of Air Traffic Control（ ATC）,the new model of combing global navigation satellite system landing system（ GLS） with instrument landing system（ ILS）,was introduced to create a more economic and precision approach strategy for landing system. Via mathematical modeling,the approach path was simulated,the errors of the two kinds of navigation source compared with standard track respectively were obtained,by setting the GLS and ILS approach data in the same rectangular coordinate system. Both the simulation and the actual flight test data show that the integrated approach strategy based on GILS（ global navigation satellite system landing system and instrument landing system） approach system can obviously improve the approach process navigation precision and integrity level,also can accelerate the approach speed and raise the level of approach security. This approach strategy is called GILS approach strategy.
