| 摘 要： | 介绍了高阶组合导航系统惯性导航系统 (INS) /全球导航卫星系统 (GNSS) /合成孔径雷达 (SAR)及其降阶模型. 降阶系统的卡尔曼滤波时间大大缩短了, 但其精度并未有大的降低. 仿真结果证明, INS/GNSS/SAR的降阶模型仍可为飞机提供满意的导航精度.

| Abstract: | This paper introduces a full_order inertial navigation system(INS)/global navigation satellite system(GNSS)/synthetic aperture radar(SAR) integrated navigation system and its reduced_order model. The computation time of Kalman filter for reduced_order model is decreased with little loss in accuracy. The simulation results prove that the reduced_order model can also provide satisfactory accuracy for aircraft navigation. |
