A research team composed of Japanese experts has developed the highest precision atomic clock ever manufactured. This optical lattice clock is extremely sensitive and can detect changes in the gravity of the earth, allowing scientists to measure time with an astonishing 17-digit accuracy. In addition, it can also be used to greatly improve the GPS tracking system, detecting a minimum height difference of 10 cm. The Japanese research team stated that this is an important step towards the development of the most accurate measuring device in human history. Atomic clocks are used to set international atomic time or coordinated universal time. They are different from Greenwich Mean Time used by most of us, but they are more accurate. Over time, even atomic clocks lose accuracy and must be adjusted to correct minor errors. The reduction in accuracy is related to the so-called "Dick effect", which is the unnecessary noise generated by the laser of the atomic clock. The optical lattice clock developed by Japanese researchers avoids this problem and is more stable, requiring no frequent adjustments. This new atomic clock was developed by Professor Minto Katori of the University of Tokyo and his team with the help of Professor Victor Frambaum of the University of New South Wales in Australia. Frambaum said that the light lattice clock is like an egg cell on the turf with atoms in it. "Ionic clocks usually have only one atom, and you have to wait a long time to achieve the desired accuracy. The newly invented atomic clock can manipulate thousands of atoms and can get results faster." In addition to being more precise, this optical lattice clock can also be used to find underground minerals and hydrocarbons. GPS relies on incredibly accurate timing, and GPS with higher accuracy can naturally play a greater role. The GPS tracker maintains communication with the satellite, which is responsible for reporting location and time. The computer in the tracker compares its time with the time reported by the satellite and uses the difference to calculate their bearing. Light travels at a speed of 186,000 miles per second (about 300,000 kilometers per second). If the satellite time lags behind the GPS receiver by a thousandth of a second, the receiver can calculate the distance between it and the satellite as 186 miles (about 300 kilometers). Frambaum said: "Our accuracy in measuring the frequency of atomic clocks can reach 17 digits. Its accuracy is surprisingly high, and it can even detect differences in the earth's gravitational potential. In the gravitational field, time goes slower The speed of the clock depends on the strength of the gravitational force of the object. "He pointed out that the atomic clock developed by Japanese researchers can also be used for oil exploration. "Because oil is a low-density liquid, the gravity of oil is lower than that of nearby rocks. With this atomic clock, you can explore minerals and apply them to the global positioning system of all platforms, including cars, planes, and spaceships, for real-time relative Geodetic survey.
