Researchers in Italy are hoping to measure Earth's rotation using a laser-based gyroscope installed deep underground, with enough experimental precision to reveal measurable effects of Einstein's ...

As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in ...

A team of scientists has developed a novel way to measure variations in the Earth's rotation. In their paper published in the journal Nature Photonics, the team explains how their new approach works ...

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 ...

A room-sized ring laser interferometer in Germany can track changes in the length of Earth’s day with millisecond precision. Precise measurements of the length of an Earth day are essential for ...
