| Abstract: | This paper introduces design of high-stability frequency source based on GPS.The pulses per second signals of GPS which has very good accuracy and long-stability with VCXO(Voltage Control Crystal Oscillator),DSP(Digital Signal Processor)and CPLD(Complex Programmable Logic Device) to form a control circuit.Through the design of intelligent control algorithms with primary,which is used for the statistical analysis and control of the output frequency of VCXO.The short-term jitter of GPS signal is sieved.The frequency source finally output high-stability frequency.The experiment result shows that the system meets the functions and the requirements of design and works reliably. |
