惯性组合误差射前等效补偿方法研究

Research on the equivalent compensation of IMU error before launching

为了解决原有的惯性组合工具误差射前修正的不能准确分离加速度计零次项与一次项的缺点 ,在分析弹道特性和工具误差补偿模型的基础上 ,提出了加速度计误差射前等效补偿方法 ,实现了在导弹临射前对纵向加速度计零次项和一次项误差的等效补偿。

In order to overcome the shortcoming of the old compensation method of IMU error just before launching which could not separate the zero coefficient and linear coefficient of the accelerometer accurately, a method of compensating the accelerometer error before launching is presented in this paper on the bases of analyses of the trajectory's characteristic and the instrument error compensation model. The equivalent compensation of the zero coefficient and linear coefficient of lengthways accelerometer before missile's launching is realized.
