摘　　要：飞机着陆段的安全性至关重要,高精度导航系统是其安全着陆的保证。针对机场使用的局域差分GPS抗干扰性差、可靠性差等问题,提出了一种高精度组合导航方案,以局域差分DGPS和外部高度阻尼的SINS/RA为子系统,利用卡尔曼滤波进行信息融合。仿真结果显示,该方案高度通道测量误差达到0.2 m以下,满足飞机着陆对导航系统精确度要求,验证了该方案的正确性和有效性。The safety is vital in aircraft landing phase, and a high-precision navigation system is the guarantee for a safe landing. In order to avoid the poor anti-jamming and reliability of local differential GPS in airports, this paper proposes an integrated navigation scheme, which use local differential GPS in- tegrated with SINS and external highly damping and fuse information by Kalman filter. The simulation re- suits indicate that measuring error in height channel is lower 0.2 m, meets the precision requirement of aircraft landing for navigation system, and validates the correctness and validity of the scheme.
