*1)challenges* : Atomic clocks have sophisticated technology. They could stop working because of different reasons. It's not only Indian navigation satellites, but atomic clocks in satellites of Galileo (European Union's navigation satellite system) had also failed earlier. NAVIC was approved by the government nearly 12 years ago at a cost of Rs 1,420 crore to establish an indigenous satellite based navigation system to provide position, navigation and timing services over the Indian landmass and surrounding region extending up to 1,500 km. Though the indigenous navigation system is very much operational, it is not as popular as the American GPS in the country because the receiver and mobile chipset needed to access the desi system have not been commercialised. *2)Accuracy* : The accuracy of an atomic clock depends on two factors , The first factor is the temperature of the sample atoms , The colder atoms move much more slowly , allowing longer probe times , The second factor is the frequency and intrinsic width of the electronic transition , Higher frequencies and narrow lines increase the precision . *3 accurate atomic clock: Physicists in Germany have built the most accurate timepiece on Earth, achieving unprecedented levels of accuracy with a new atomic clock that keeps time according to the movements of ytterbium ions. *4 atomic clock other than rubidium : quantum logic clock based on individual ions of beryllium and aluminium. quantum logic clock based on individual ions of beryllium and aluminium. optical lattice clocks based on strontium-87 and ytterbium-171.
logic to smjhate sir .... ratta jaisa lgra hai !
