The method of SINS alignment with distance-transfer-unit aiding is studied. The SINS/DTU system's observable matrices in different moving bases are obtained by using the method of analyzing the piece-wise constant system. The observabilities of SINS/DTU integration system are analyzed according to the singular-values of the observable matrices. SINS/DTU integration system and SINS/GPS integration system are compared. The simulation results are given. The results indicate that SINS autonomous alignment can be completed by SINS/DTU integration. But the obsevabilities of SINS/DTU integration are slightly less than that of SINS/GPS integration, and the former needs a longer time than the latter in moving base alignment.

研究利用里程计(DTU)辅助实现惯性导航系统(SINS)运动基座下初始对准.利用分段线性定常系统分析方法,提取了不同运动基座情况下SINS/DTU组合系统的可观测性矩阵;通过计算可观测性矩阵奇异值的大小,定量分析了SINS/DTU组合系统的可观测度;比较了SINS/DTU组合系统和SINS/GPS组合系统的对准机理;并进行了系统仿真.结果表明,这种基于SINS/DTU组合的方法能够实现SINS系统的自主式初始对准;但与SINS/GPS组合系统相比,系统的可观测度稍弱,所需对准时间稍长.

By establishing the system model of moving-base alignment velocity match, the factors that influenced the transfer alignment were analyzed, such as lever arm effect, flexible vibrations, etc. The off-line simulation was made using the navigation data sampled from the trial in sigmoid flying. It is concluded that alignment precision satisfies the performance requirements, that is level 1′, azimuth 6′, platform-drift 0.02 (°)/h, and alignment time 15 min. The simulation result...

By establishing the system model of moving-base alignment velocity match, the factors that influenced the transfer alignment were analyzed, such as lever arm effect, flexible vibrations, etc. The off-line simulation was made using the navigation data sampled from the trial in sigmoid flying. It is concluded that alignment precision satisfies the performance requirements, that is level 1′, azimuth 6′, platform-drift 0.02 (°)/h, and alignment time 15 min. The simulation result shows the scheme proposed satisfies the system performance and is practicable.

通过建立动基座对准速度匹配的系统模型,对影响传递对准的一些重要因素如杆臂效应、挠曲振动等进行了分析,按照既定的载机机动方案采集飞行数据进行离线仿真。仿真结果表明,自适应卡尔曼滤波可达到对准时间15min,水平对准误差小于1′,方位对准误差小于6′,水平轴陀螺测漂小于0.02(°)/h的指标要求,证明S形机动速度匹配自适应卡尔曼滤波方案设计正确。利用机载试验数据进行的离线仿真验证,在将自适应卡尔曼滤波理论应用于工程实际方面以及对空中动基座对准方案的试验验证方面具有创新性。
