摘要:

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。

Abstract:

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.
