摘    要:为满足高超声速飞行器的高动态特性对捷联惯性导航系统的导航精度提出的更高要求,在分析高超声速飞行器高动态运动频谱特性的基础上,研究了高动态环境下的捷联惯导高阶姿态积分算法。通过高超声速飞行器运动特性仿真,对比分析了不同阶次姿态积分算法对捷联惯性导航系统精度的影响。仿真结果表明,在高动态环境下,采用高阶姿态积分算法能有效提高捷联惯导导航精度。

关 键 词:高动态  捷联惯导  姿态解算

Abstract:The high dynamic navigation accuracy of strapd characteristics of hypersonic vehicles put forward a higher requirement to the own inertial navigation system ( SINS). Attitude solution algorithm is the im- portant factor affecting the accuracy of SINS. On the basis of the study of hypersonic vehicles' spectral characteristics of high dynamic movement, this paper made study of the SINS high- order attitude integral algorithm at high dynamic environment. Compare and analyze the influences of the different orders'atti- tude integral algorithm on the accuracy of SINS through the simulation of hypersonic vehicles' motion characteristics. The simulation results show that the navigation accuracy of SINS is improved effectively when using the high- order attitude integral algorithm at high dynamic environment.
Keywords:high dynamic  strapdown inertial navigation system  attitude solution
