惯导托架校准是飞机装配过程中非常重要的一部分工作,但是传统的校准方法存在精度低、耗时、费力等问题。为解决这些问题,设计了一种高精度、高效率的惯导托架自动校准算法。该方法通过建立静力学数学模型,结合传统惯导校准和位置误差最高点不动调平法的思想,对平台循环进行倾斜信息测试、判断和最高点不动调平。该方法的校准精度较高,极大缩短了校准时间,提高了校准效率。
INS calibration is a very important part of aircraft assembly process, but the traditional calibration methods have the problems of low precision, time-consuming and laborious. In order to solve these problems, a high precision and high efficiency automatic calibration algorithm of inertial navigation system was designed. By establishing the mathematical model of static mechanics and combining the idea of traditional inertial calibration and the highest point of position error, the method of slope information test and judgment and the highest point leveling are adopted. The calibration accuracy of the method is high, which greatly shortens the calibration time and improves the calibration efficiency.
