摘要	The carrier phase (CP) technique based on the global positioning system is a widely applied spatial tool for precise time and frequency transfer. However, the traditional CP technique considers the receiver clock offset to be a white noise stochastic process, which introduces unknown errors into the model and thereby compromises time and frequency transfer performance. To improve the performance of the traditional CP technique, an atomic clock modelling CP time transfer (AMCP) method is proposed. A first-order, one variable grey model is employed to establish the receiver clock offset forecast model for the formation of prior information. The results show that the AMCP approach, which uses an atomic clock correlation between nearby epochs, outperformed the traditional CP technique. The noise level of the AMCP solution was improved by 7.7% for the NTSC-PT11 link, and the improvement for the other three time links were all similar to 2.0%. The average improvement of the absolute jumps in the day-boundary discontinuities was similar to 13.1%. Additionally, the frequency stability of the AMCP solution was improved, and the mean improvement was 10.2, 12.0, 10.7, and 8.3% for TLT4-PT11, USN9-PT11, WAB2-PT11, and NTSC-PT11, respectively.
