摘要

针对现有三轴加速度计非正交误差角测试方法成本高、现场测试能力不足以及对加速度计测试位置精度要求高的问题

提出一种基于椭球假设的现场无依托测试方法。在只考虑三轴加速度计非正交误差角因素下

建立了三轴加速度计误差模型。实验结果表明:采用椭球假设现场测试方法可以不依赖外部辅助设备

通过绘制椭球的圆球程度可以直观观察到非正交误差角对加速度计的影响

同时可以对加速度计非正交误差角进行补偿。

Abstract

To overcome the problems of high cost

insufficient on-site test ability and high precision demand for accelerometer test location that existing triaxial accelerometer non-orthogonal error angle test method has

a new test method based on ellipsoid hypothesis is proposed for on-site use. Considering only non-orthogonal error angle factors

an error model for triaxial accelerometer is established. Experimental results show that using proposed onsite method based on ellipsoid hypothesis without auxiliary equipment can realize accelerometer non-orthogonal error compensation and the impact of non-orthogonal error angle on accelerometer can be observed visually by the degree of sphere of drawing ellipsoid.
