The Research Of Compensation Processing Technology Based On Precision Time-frequency System

Aging atomic clock drift will make its output becomes unstable, it is not includingtemperature drift, affecting the accuracy of atomic clocks the output and stability of oneof the important reasons. This article from study on the short-term aging of highaccuracy constant temperature crystal oscillator drift starting with careful observation ofwork temperature under constant temperature crystal oscillator drift phenomena ofageing, based on observation data analysis of the short-term aging of constanttemperature crystal oscillator drift pattern, the establishment of a mathematical model ofthe short-term aging drift. According to the mathematical model for artificial aging onconstant temperature crystal oscillator drift compensation, has been made more obviouseffect. Will high precision thermostat Crystal vibration aging drift for artificialcompensation of thought application to rubidium atomic clock Shang, establishedrubidium atomic clock short-term aging drift mathematics model; under theory analysisand the has some rubidium atomic clock medium-term, and long-term of drift rate data,established has rubidium atomic clock forecast and the compensation programme, andfor simulation validation, combination experimental results and frequency benchmark,implementation on rubidium atomic clock aging drift of compensation and improved.
