中文摘要: 用三轴转台标定捷联惯组时,需要对三轴转台引北,用于精准测量捷联惯组相对地球北向的角度。为了减少引北带来的繁重工作量,在研究传统六位置标定方法的基础上,设计了十二位置标定方法。给出了十二位置翻转编排,建立了捷联惯组器件误差参数模型,详细推导了求解误差参数的方程式,并在高精度三轴转台上进行了试验验证。结果表明,在对三轴转台无引北的情况下,十二位置标定方法仍能标定出捷联惯组的24个器件误差参数,且精度与六位置标定方法相当,达到了预期目的。

Abstract:When calibrating the Strapdown Inertial Unit with the three-axis turntable, it is necessary to lead the three-axis turntable to the north, which is used to accurately measure the angle of the Strapdown Inertial Unit with respect to the north direction of the earth. In order to reduce the heavy workload caused by looking for north reference, based on the study of traditional six position calibration method, a twelve position calibration method is designed. the twelve position flip arrangement is given, the error parameter model of Strapdown Inertial Unit device is established, and the equation for solving the error parameters is derived in detail, and the twelve position calibration method is verified through the experiments on a high precision three axis turntable. The results show that the twelve position calibration method can still calibrate the twenty four error parameters of Strapdown Inertial Unit device, and its accuracy is equivalent to that of the six position calibration method, as a result, the predict purpose has been achieved.
