About
This naval atomic clock is designed for high-precision geodetic measurements, including determining the Earth's shape and size, monitoring surface changes, and measuring gravitational variations. It employs calcium ion trapping with stable RF/DC electronics and a high-finesse cavity for narrow-linewidth clock lasers. The system features laser frequency stabilization, sub-1 Hz laser operation at 729 nm, and Allan deviation measurements to ensure exceptional timing accuracy
