论文摘要
在地球上的单个位置测量其角度旋转速率相对于天体框架，具有敏感性以访问微小的透射效果是一项极具挑战性的任务。 Gingerino是一个大型框架激光陀螺仪，在意大利格兰·萨索（Gran Sasso）的地下实验室内无人看管。使用标准线性回归方法从gingerino数据中回收了主要的大地测量信号，即每年的和钱德勒的摇摆，每天的极性运动和一天的长度，表明敏感性大于1 prad/s，因此接近对基于地球的透镜测试的要求。
Measuring in a single location on Earth its angular rotation rate with respect to the celestial frame, with a sensitivity enabling access to the tiny Lense-Thirring effect is an extremely challenging task. GINGERINO is a large frame ring laser gyroscope, operating free running and unattended inside the underground laboratory of the Gran Sasso, Italy. The main geodetic signals, i.e., Annual and Chandler wobbles, daily polar motion and Length of the Day, are recovered from GINGERINO data using standard linear regression methods, demonstrating a sensitivity better than 1 prad/s, therefore close to the requirements for an Earth-based Lense-Thirring test.
