具有极高灵敏度的绝对转速传感需要多个大型陀螺仪的组合才能获得完整的旋转矢量。我们报告了一个四组件，四面体激光陀螺仪阵列的建设和运行，有一个五层楼大，位于近地面，地下实验室。结果表明，在六周以上的时间内，可以以亚弧秒分辨率实现完整的地球旋转矢量重建。
Absolute rotation rate sensing with extreme sensitivity requires a combination of several large scale gyroscopes in order to obtain the full vector of rotation. We report on the construction and operation of a four-component, tetrahedral laser gyroscope array as large as a five story building and situated in a near surface, underground laboratory. It is demonstrated that reconstruction of the full Earth rotation vector can be achieved with sub-arcsecond resolution over more than six weeks.
