British scientists claim that they have found an alternative to the Global Positioning System (GPS) without resorting to any space technology. Studies have found that lasers can confine and cool atoms placed in vacuum, reducing the temperature to above absolute zero. One millionth of a degree. At this temperature, atoms are extremely sensitive to changes in the Earth's magnetic and gravity fields. Researchers can use these results to confine atoms on a small device, study their fluctuations, and locate them Movement, and accurately find out where they are. At this time, the tracking and positioning work will be completed by a device that is only 1 meter long. The key is how to make it a miniature device so that it can be installed on a smartphone. middle.
