    • A device for measuring a frequency offset of an atomic clock and a control method thereof are provided to implement a stable synchronization system by using the method to add the weight to the measured current frequency offset value. A device for measuring a frequency offset of an atomic clock(100) includes a phase comparator(10), a defective data deleting unit, an average calculator(30), a filter(40), a phase change value setting unit, a frequency offset calculation unit(60), a weight value calculation and application unit, a control signal output unit(80), and a frequency controller(90). The phase comparator compares the phase difference of the second pulse outputted from the frequency controller and the reference second pulse. The defective data deleting unit deletes the defective data among the data outputted from the phase comparator. The average calculator takes an average of the data outputted from the defective data deleting unit. The filter performs filtering of the averaged data by the line fitting method. The phase change value setting unit determines whether the phase of the signal outputted from the filter is changed or not. The frequency offset calculator calculates the frequency offset based on the data outputted from the phase change value setting unit. The weight value calculation and application unit determines whether the weighted value is applied to the frequency offset data. The output unit outputs the data with the calculated weight. The frequency controller outputs the second pulse based on a control signal outputted from the control signal output unit.
