Highly-accurate real-time syntonization using a GPS single-frequency receiver with an intelligent atmosphere forecasting model
F.-R. Chang C.-L. Cheng · 2005
A low-cost, highly-accurate real-time GPS carrier phase frequency syntonization system based on a single-frequency receiver is presented. By using the atmosphere free model of the carrier phase with the neural-wavelet filter, and performing the time-difference operation, the low-cost oscillator can be automatically steered to obtain very high frequency accuracy and stability in the short term (1 sec.) as well as in the long term (1 day).
