基于飞控仿真系统的SINS/BDII 组合导航仿真

为验证SINS/BDII 组合导航系统的性能，采用一种基于飞控仿真系统生成轨迹的方法。通过Visual C++ 编程语言以及飞控原理设计出模拟飞行仿真软件，运用双子样旋转矢量算法对转动的不可交换性误差进行有效补偿， 利用间接法滤波设计SINS/BDII 组合导航系统卡尔曼滤波器。验证结果表明模拟飞行状态下SINS 及组合导航系统算 法是正确的。该轨迹生成方法具有工程应用价值。

SINS/BDII Integrated Navigation Simulation Based onFlight Control Simulation System

In order to verify the performance of SINS/BDII integrated navigation system, a method based on the flight control simulation system to generate the trajectory is adopted. The flight control simulation software is designed by Visual C++ programming language and flight control principle. The non-commutative error of rotation is effectively compensated by the double sub-sample rotation vector algorithm. The SINS/BDII integrated navigation system Kalman filter is designed by indirect filtering method. The verification results show that the SINS and integrated navigation system algorithms is correct under simulated flight conditions. The trajectory generation method has engineering application value.
