2019年12月11日 · Atomic gyroscopes can enable accurate navigation for submarines, aircraft, missiles, ships and satellites by giving them a way to stay on course when no visual or electronic guidance system is available. Eventually, when the associated lasers and electronics are miniaturized, the sensor can be put to numerous uses.

2012年3月7日 · Recent progress on atomic gyroscopes has demonstrated that AIG is an ultra-high precision gyroscope for strategic grade inertial navigation in the future, and ASG is a high performance gyroscope which features both high precision and compact size.

Atomic gyroscopes are highly sensitive quantum devices that use the nuclear spins in an atomic gas for rotation measurement. Miniature Atomic Gyroscopes (MAG) employ noble-gas nuclear spins as high-coherence rotation sensors. Advanced prototypes exist but the application remains confined to laboratory environments.

There are two types of atomic gyroscope. The Atomic Interferometer Gyroscope (AIG), which utilizes the atomic interferometer to sense rotation, is an ultra-high precision gyroscope; and the Atomic Spin Gyroscope (ASG), which utilizes atomic spin to sense rotation, features high precision, compact size and the possibility to make a chip-scale one.

2007年11月9日 · For the likes of satellites, orbiting telescopes, and probes navigating through deep space, the systems of choice to point the way are based on gyroscopes aligned with a distant reference star. To study predictions of general relativity such as frame dragging, the effects of which would be seen as tugs on the rotation axis of the gyros, high ...

2012年12月1日 · The atomic spin gyroscope (ASG), based on spin-exchange relaxation-free co-magnetometers, is poised to become the next generation of high-precision inertial sensors.

Atomic gyroscopes can be used to measure carrier's rotation information by atomic spin or Sagnac interference effect, which have the characteristics of high precision, small volume, and so on. In the first part, atomic gyroscopes are discussed with …

Atomic gyroscopes are a new, recently envisioned, type of atomic MEMS. Nuclear-spin based gyroscopes were identified in a comparative analysis of compact gyroscopes as a class of promising rotation sensors that can rival state-of-the-art gyroscopes.

2019年7月11日 · Researchers at the National Institute of Standards and Technology (NIST) have upgraded their compact atomic gyroscope to enable multitasking measurement capabilities and measure its performance, important steps toward practical applications.

Atomic Gyroscope The NIST team has demonstrated a compact atomic gyroscope design that could, with further development, be portable, low power, and accurate enough to be used for navigation. Gyroscopes, traditionally based on mechanical components that spin or vibrate, are common in navigation applications and
