| 摘 要： | 基于伪卫星的进近着陆系统具有机动灵活、成本低、抗干扰性能好等优点,可满足小型机场或临时机场对着陆系统的迫切需求,具有良好的应用前景。本文从GDOP的角度对机场伪卫星星座布局进行了研究,提出了3颗和4颗伪卫星情况下的最佳布局。仿真结果表明这两种布局均达到了机场伪卫星进近着陆系统对HDOP的要求,对机场伪卫星着陆系统的实施具有重要的参考价值。

| Abstract: | The pseudolite-based approach and landing system has such advantages as flexibility,low cost and better capacity of anti-jamming,thus it has bright outlook for meeting the urgent need of landing system in temporary or small airport.The paper analyzes the GDOP of the airport pseudolites＇ layout,introducing the two best layouts on condition of 3 and 4 APLs.The results show that both of the layout meet the requirements of the approach and landing system,which has important significance for the implementation of pseudolite-based approach and landing system. |
