Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...

Italian scientists dip deep for laser experiments to measure Earth’s rotational effects at greatest ever sensitivity. GINGERino ring laser gyroscope at the underground labs of INFN in Gran Sasso, ...

Laser gyroscopes represent a pivotal technology in measuring Earth’s rotation with unmatched precision, utilising the Sagnac effect to detect minuscule angular variations. These instruments, often ...

Accurately sensing rotation is important to a variety of technologies, from today's smartphones to navigational instruments that help keep submarines, planes, and satellites on course. In a paper ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...
