平台系统动基座标定方法

Calibration technique of inertial platform system on a moving base

惯性器件的一次通电稳定性相对较高,如果能够在载体上对平台系统进行误差参数的标定,排除多次通电的不重复性误差,可以显著提高误差参数的补偿精度,有效提高惯性系统的导航精度、最终定位与打击精度。讨论了一种平台惯性系统在载体安装条件下进行自主标定的新方法。这一方法使用平台本身的框架结构进行标定运动,利用载体主惯导系统的信息,在动态环境下进行平台误差参数的标定。

The calibration technique of inertial platform system is a key of the error compensation.The accuracy of the calibration makes a directly affection on the precision of navigation.A new scheme of calibration of the inertial platform system is introduced.By this way,the platform errors can be calibrated using the information of the master inertial navigation system on a moving base.
