An international team of researchers have developed a new type of gyroscope that is the first to measure the “wobble” in the rotational axis of the Earth from a ground-based laboratory. Astronomers ...

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 ...

The modern smartphone is only possible because of sensors. Their svelte form factor conceals accelerometers, magnetometers, temperature sensors, a GPS unit, and gyroscopes. They all consume volume and ...

No modern car (nor any smartphone) is considered complete without some sort of navigation product. Indeed, even my wife’s bottom-of-the-line, not-so-smartphone has a cell-tower-based navigation system ...

(PhysOrg.com) -- When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why. The ...

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 ...

We propose and analyze a superluminal ring laser gyroscope (RLG) using multilayer optical coatings with huge group delay (GD). This GD assisted superluminal RLG can measure the absolute rotation with ...

The rotating-mass gyroscope, which lies at the heart of inertial measurement units (IMUs), has served very successfully from the 1930s to the 1970s, guiding astronauts, spacecraft, missiles, and more.

We have created a simple model to analyze the restrictions on superluminal ring laser gyroscopes arising from the absorption of coating materials. For a ring laser gyroscope with a cavity length of 15 ...

If you want to view the distant Universe with the highest sensitivities and the smallest amounts of contamination possible, your best bet is to go to space. The Hubble Space Telescope, launched in ...

In the 1850s British railway companies started introducing a single standard time to make their timetables consistent. Before that, every city would set its own clock based on the observation of the ...
