一种车载筒弹惯导装置不开箱标定方法

随着时间的推移,惯测装置中惯性器件误差参数会发生变化,从而使惯性器件的精度降低,因此必须对惯导装置进行误差补偿。针对筒弹开箱标定工作量大,成本高等问题,本文在车载筒弹状态下,以车的一定机动作为激励方式,设计了一种不开箱标定方法。在分析惯性测量元件误差的基础上,建立了误差输出模型,将理想装置与待测装置的输出量进行比较,利用比较偏差对待测装置进行标定。仿真结果表明,该标定方法能够对误差进行补偿,进而提高惯导系统的导航精度。

Calibration without opening box for vehicle silo missile's inertia instrument

The error parameter of inertia instrument in inertia measure device may change with time and reduce and need to be compensated.Since the open tank calibration is of heavy work and high cost,this paper designs a calibration method for inertia instrument of onboard silo missile.The method doesn't need to open the box and take vehicle's movement as actuator.The error model is established based on the analysis error of inertia measure component,and the differences between the output of ideal device with the out...
