摘　　要：介绍了一种卫星用高可靠性惯性敏感器,它的六个陀螺的输入轴按正十二面体安装,任意三个陀螺工作均能给出卫星的三轴姿态信息,这样在单个陀螺平均寿命一定的条件下,惯性敏感器的可靠性大大提高。文中还介绍了该方案的其它优点和结构设计巧妙之处,目前已应用该方案设计、加工、调试出实用的惯性敏感器,并通过了各项地面试验,适用于高精度、长寿命的三轴稳定卫星。This paper introduces a high-reliable inertial reference unit (IRU) for satellite, whose six gyroscopes are assembled as right twelve planes?body. The satellites attitude information can be supplied even if there are only three gyros in running. So the reliability of this type of IRU is much better than that of a single gyro. The paper also presents the scheme抯 advantages and mechanical design抯 ingenious idea. Now a real IRU has been designed, manufactured, adjusted and passed a series of tests on ground. It is adaptable for three-axes steady satellites with high accuracy and long life.
