The National Center for Physics and Mathematics (NCPM) in Sarov has announced that the development of nuclear clocks will significantly improve the accuracy of satellite navigation systems such as GPS and GLONASS. In addition, these clocks will allow for highly accurate measurements of fundamental physical constants, including the gravitational constant, opening up new opportunities to test the foundations of general relativity on a cosmological scale.
Nuclear clocks, due to their small size and high stability, will surpass atomic clocks in accuracy and open the possibility of registering the influence of the gravitational field on the frequency of transitions.
Such clocks will help solve problems of fundamental physics, detect mineral deposits, and create high-precision geoid navigation maps
According to the scientist, the development of nuclear clocks is a priority for leading research centers around the world. Despite the long-standing idea of using the isomeric transition of thorium-229 as the basis for clocks, it was only in 2024 that the first significant practical achievements were made in this area.
