摘要
以捷联惯导等效旋转矢量算法为基础,针对捷联惯导多子样算法在不同动态环境下的误差精度可能不同的问题,设计了几种动态运动轨迹,通过对轨迹分别进行二子样、三子样、四子样等效旋转矢量算法惯性导航仿真验证。结果表明,并非采样子样数越高,算法精度越高,对于角运动并不剧烈的运载体采用低子样算法效果反而更好。
Based on the strapdown inertial navigation equivalent rotation vector algorithm,several dynamic motion trajectories are designed for the problem that the error precision of the strapdown inertial navigation multi-subsample algorithm in different dynamic environments may be different. The inertial navigation simulation of the equivalent rotation vector algorithm of two sub-samples, three sub-samples and four sub-samples is verified by the trajectory. The results show that it is not that the higher the number of sampled sub-samples, the higher the accuracy of the algorithm, but the effect of using a low sub-sample algorithm for carriers that are not vigorous in angular motion is better.
