< P > Modern GPS systems and electronic devices use approximately & nbsp; < strng > 400 atomic clocks , located throughout the planet, which ensure high coordinate determination. The main components of the atomic clock are & nbsp; < strong > Osculator & nbsp; & ndash; periodic oscillation generator & ndash; and & nbsp; < strng > trigger mechanism , which these oscillations summarize. The basis of the work of such watches is & nbsp; < strong > radiation of atoms , which change their energy states with a certain frequency.

~ ~ < P > Traditional atomic watches use microwave radiation to induction of atomic oscillations, however, & nbsp; < strong > Optical watches & nb. a second for shorter gaps time.

& laquo; today's nuclear clock enables GPS systems to ensure a few meters positioning accuracy. With the optical nuclear clock, you can reach a few centimeters & raquo ;, & ndash; Ni Minko notes from the University of Purdy. < P > To make an optical atomic clock compact, researchers from the US and Sweden & nbsp; developed & nbsp; < strong > Microbinky technology , which generate the spectrum that generate the spectrum of spectrum. frequencies. One of these frequencies can be synchronized with a laser, which is attributed to the Rsquo; This eliminates the need in & nbsp; < strong > large laser systems , making the device much smaller.

< p > Since the frequency of atomic oscillation reaches & nbsp; < strng > hundreds of teraegraces , it must be reduced for electronic circuits. New & nbsp; < strong > chips with microbagins & nbsp; nbsp; became a key solution, converting optical signals into suitable for fit processing & nbsp; < strng > radio frequencies .

& laquo; we managed to achieve simultaneous self -reference and accurate alignment of frequencies, which is critical for the stability of the entire system & raquo ;, & ndash; It is said in the researchers' report. < P > Due to this development, it became possible & < strong > Mass production of optical nuclear watches , which opens prospects for improving navigation, autonomous transport and monitoring.
