摘要
由于飞行器动态模型航迹生成算法与惯性导航系统算法原理存在差异,无法直接仿真分析惯性传感器不同误差特性对惯性导航系统动态性能的影响。基于飞行器动态模型航迹数据,提出一种捷联惯性导航系统高精度动态仿真实现方法,设计了惯导参数动态计算误差并行补偿方案,实现了对导航系统动态仿真过程中导航参数计算误差的有效分离。在搭建的仿真平台上,有效验证了所提出仿真方法的性能,为实际惯性传感器选型和指标选择提供支撑。
There are differences between the generation algorithm of vehicle dynamic model with the algo- rithm of inertial navigation system in scheduling principle. So the different error characteristics of inertial sensors can＇t analysis directly the affect of the dynamic performance of the inertial navigation system. Based aircraft dynamic models track data, we proposed a high- precision dynamic simulation method of SINS, which is the inertial navigation system dynamic parameter errors of the parallel compensation scheme to achieve effective separation of the dynamic simulation of the process of the inertial navigation system navigation parameters calculation error. Finally, we build the simulation platform of the ystem, which validate the performance of the method well. So it may be choosed to provide support for the actual selection of inertial sensors and indicators.
