环形激光陀螺仪装有三个激光陀螺仪,它们在空间彼此相差90°。这些陀螺和加速度计分别给出了飞机俯仰、旋转、偏轴的精确加速率,和沿三个陀螺轴线方向每一方向的线性加速度,电子计算机完成导航、高度、速度所需要的全部计算。环形激光陀螺仪已由霍尼威耳航空电子部研制成功.1981年各研制阶段的已全部模型完成,1982年开始系统的飞行试验, The ring laser gyroscope is equipped with three laser gyros, which are 90 ° apart from each other in space. These gyros and accelerometers give the exact rates of pitch, roll and off-axis acceleration of the aircraft and the linear accelerations in each direction along the three gyroscope axes. The computer calculates all the calculations required for navigation, altitude, and velocity. Ring laser gyro has been successfully developed by Honeywell Aeronautic Electronics Division in 1981 all stages of the development of all the models have been completed in 1982 began a systematic flight test,
