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.

检测敏感轴非正交方向 IMU 的技术

摘要

本文讨论了用于检测敏感轴非正交方向的惯性测量单元 (IMU) 所开发的技术及其应用结果。该方法是在国际空间站 (ISS) 六轴角速率传感器单元计划下联盟号系列航天器运输系统现代化期间，作为捷联惯性导航系统 (SINS) 的 IMU 开发的一部分而提出的。 ARS）和敏感轴非正交方向的加速度计。 2002 年至 2023 年在 86 号联盟号和进步号航天器上进行的地面和飞行测试的积极结果证实了所提出方法的有效性。
