Abstract :
A low-cost, highly-accurate and real-time GPS carrier phase disciplined oscillator system based on a single-frequency receiver is presented. By using the atmosphere-free model of the carrier phase with time-series-noise-free, and performing the time-difference, the low-cost oscillator could be automatically steered to obtain the very high frequency accuracy and stability in the short term (1 sec.) as well as in the long term (1 day)
