| 摘 要： | 二自由度陀螺仪使用中存在框架误差不是一个新问题,以往推求框架误差表达式时过程繁,易出错,且没有与不同定义的欧拉角联系起来;原则上欧拉角组有12种,不同定义的欧拉角框架误差表达式不同。陀螺仪在运载体上有六种安装方式,文中介绍推导框架误差表达式的简易方法,它不因欧拉角定义不同而带来麻烦。

| Abstract: | It is not new that there exist gimbal errors of two-degree-of-freedom gyrocope in use.In past time the process of deducing equations for expressing of gimbal errors was too complicated,leading to mistakes and to the lack of connection with Euler Angles of different definition;In principle,there are twelve kinds of Euler Angle groups and as a result of this the mathematic expressions of Euler Angle gimbal errors for different definitions are various.There are six modes of installation of gyroscopes on the vehicle system.In this article is described a fairly simple method for deducing equations of gimbal error which is free of trouble in the case of different definitions of Euler Angles. |
