An atomic clock is based on a system of atoms which may be in one of two possible energy states. A group of atoms in one state is prepared, then subjected to microwave radiation. If the radiation is of the correct frequency, a number of atoms will transition to the other energy state. The closer the frequency is to the inherent oscillation frequency of the atoms, the more atom… WebApr 9, 2024 · GPS requires precise clocks to provide astounding positional accuracy. Atomic clocks in GPS satellites keep time to within three nanoseconds—three-billionths of a second. Position accuracy depends on the receiver. You only need the time from a single NMEA string.
