Scientists at the US Naval Research Laboratory (NRL) have developed an “atomic compass” that could provide a more accurate and reliable navigation system.
The new device is called the Continuous 3D Cooled Atomic Beam Interferometer. It works on the basis of cooled atoms and does not depend on GPS.
Advantages of the “atomic compass”:
- High accuracy: can measure the position and orientation of an object with less error.
- Reliability: It works even where there is no GPS signal (for example, underwater or in space).
- Interference immunity: is not subject to signal jamming or alteration.
The “atomic compass” could become an indispensable tool for warships, submarines and spacecraft. NRL is currently continuing to work on developing this technology.
