The Using Method of IMU Testing Data Before Launching Based on the Best Guidance Precise

研究提出了一种利用捷联惯性测量组合射前测试数据,进一步提高捷联惯导精度的方法。该方法通过落点偏差估计系数将惯性测量组合测试观测方程与落点偏差联系起来。通过对落点偏差估计值的圆概率误差最小化得到落点偏差最优估计系数。讨论了具体应用的方法,并通过仿真验证了方法的有效性。

A method discussed to further improve strapdown inertial guidance by making full use of IMU data before launching, The deviation of impact point related with equations of IMU through estimating coefficient, he optimal estimating coefficients obtained by minimizing the （CEP） of the estimating error of the deviation of impact point. The application method presented and the simulation result its effectiveness.
