Abstract

The paper discusses the techniques developed for inspecting inertial measurement units (IMU) with nonorthogonal orientation of their sensitive axes and the results of their application. The methodology was proposed as part of the development of IMUs for a strapdown inertial navigation system (SINS) during the modernization of the Soyuz-family spacecraft transport system under the International Space Station (ISS) program for six-axis units of angular rate sensors (ARS) and accelerometers with nonorthogonal orientation of their sensitive axes. Positive results of the ground-based and flight tests carried out aboard 86 Soyuz and Progress spacecraft from 2002 to 2023 have confirmed the effectiveness of the proposed methodology.

检查敏感轴方向非正交的 IMU 的技术

摘要本文讨论了为检测敏感轴方向非正交的惯性测量单元（IMU）而开发的技术及其应用结果。该方法是在国际空间站（ISS）计划下联盟家族航天器运输系统现代化过程中，在开发用于捆绑式惯性导航系统（SINS）的惯性测量单元过程中，针对敏感轴方向非正交的角速率传感器（ARS）和加速度计六轴单元提出的。2002 年至 2023 年期间在 86 艘联盟号和进步号航天器上进行的地面和飞行测试取得了积极成果，证实了拟议方法的有效性。
