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 ...

Knowing the subtle variations won't help us check off more items from our to-do list, but it may help scientists build more accurate climate models. When you purchase through links on our site, we may ...

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 ...

SpaceWERX, the innovation arm of the U.S. Space Force, has awarded ANELLO Photonics a Small Business Innovation Research (SBIR) Phase I contract to develop a resonator laser gyroscope. The new ...

Back in the old days, finding out your location on Earth was a pretty involved endeavor. You had to look at stars, use fancy gimballed equipment to track your motion, or simply be able to track your ...

Renowned physicist Frederick Aronowitz, world expert on laser gyro technology, died on December 17, 2022, in Belmont, MA. He was 87 years old. Anyone who has flown in a commercial jetliner, starting ...

Scientists have figured out a way to measure the slow and tiny wobble of the Earth's axis of rotation. Their method should keep GPS systems from requiring an entire series of radio telescopes pointed ...

High-precision space-based gyroscopes are important in space science research and space engineering applications. In fundamental physics research, they can be used to test the general relativity ...
