摘要

为简化惯性测量组合(IMU)高低温标定过程,基于输入输出物理量模相等的原理,提出了一种高低温环境IMU简易标定方法,并给出了最佳标定编排。高低温环境下对一套激光陀螺捷联惯导系统进行标定试验,结果表明:与传统标定法相比,简易标定法精度满足导航级惯性导航系统的应用要求。试验证实了简易标定法的有效性。

Abstract

In order to make calibration of inertial measurement units (IMU) at different environmental temperatures more easily, this paper proposes a reduced calibration method based on the fact that the norm of outputs is equal to the magnitude of inputs for an IMU. We also derived the best calibration scheme for IMUs whose gyroscope triad and accelerometer triad are both almost or-thogonal. Calibration tests at different environmental temperatures for a laser gyroscope strapdown inertial navigation system were performed. Compared with the calibration results using a high precision turntable, parameters got from the reduced calibration method are precise enough to be used in a navigation grade inertial navigation system. The tests show that the proposed method is effective.

Key words： inertial measurement unit; calibration; different environmental temperatures
