Abstract

The paper presents a method for correcting the results of factory calibration of inertial measurement units for measurement systems. It was developed to study the spin of free-flying aircraft models in a vertical wind tunnel. Calibration is performed immediately before the test cycle. The method is based on the use of a special manual rotary calibration test rig which provides correction of errors in the output signals of triads of inertial MEMS sensors and a magnetometer triad.

使用手动校准测试台校准 IMU MEMS 传感器

摘要

本文提出了一种校正测量系统惯性测量单元工厂校准结果的方法。它的开发是为了研究垂直风洞中自由飞行的飞机模型的旋转。校准在测试周期之前立即进行。该方法基于使用特殊的手动旋转校准测试装置，该测试装置可对惯性 MEMS 传感器三元组和磁力计三元组的输出信号中的误差进行校正。
