We propose a new data analysis process that is referred to as the upsampled common-view (UCV) method, which evolved via the interpolation techniques of portable clock trips and digital signal processing. By interpolating the locally measured global positioning system (GPS) P3 code time offsets to obtain global visible common-view (CV)-like results, we increase the number of data points at each epoch; these points are not restricted to the epoch in which the observations occur. The time transfer results between two laboratories are obtained from a weighted average among all the visible GPS satellites. Daily files of GPS observation data were used in the study. We demonstrate the results of three long-baseline links among the Telecommunication Laboratories (TL) in Asia, the Physikalisch-Technische Bundesanstalt (PTB) in Europe and the United States Naval Observatory (USNO) in North America. The rapid UCV results provide time stability at the level of 100 ps at averaging times around 1 d, which is comparable to the P3 all-in-view (AV) results. Comparing the UCV results with precise point positioning (PPP), the root mean square (RMS) of the double differences for the TL-PTB, TL-USNO and USNO-PTB links are 0.29 ns, 0.38 ns and 0.34 ns, respectively, during a period of 40 d. The low RMS values show that the smooth UCV results are close to the PPP results.

我们提出了一种新的数据分析过程，称为上采样共视（UCV）方法，该过程是通过便携式时钟行程和数字信号处理的插值技术发展而来的。通过对本地测量的全球定位系统（GPS）P3代码时间偏移进行插值以获得类似全局可见公共视图（CV）的结果，我们增加了每个时期的数据点数量；这些点不限于观察发生的时代。两个实验室之间的时间传输结果是从所有可见GPS​​卫星之间的加权平均值获得的。该研究使用了GPS观测数据的每日文件。我们展示了亚洲电信实验室（TL）之间三个长基线链接的结果，欧洲的Physikalisch-Technische Bundesanstalt（PTB）和北美的美国海军天文台（USNO）。快速UCV结果提供的时间稳定性为100 ps，平均时间约为1 d，这与P3全视角（AV）结果相当。将UCV结果与精确点定位（PPP）进行比较，在TL-PTB，TL-USNO和USNO-PTB链接的双差的均方根（RMS）分别为0.29 ns，0.38 ns和0.34 ns。 40天的期限。较低的RMS值表明，平滑的UCV结果接近PPP结果。TL-PTB，TL-USNO和USNO-PTB链接的双重差的均方根（RMS）在40 d期间分别为0.29 ns，0.38 ns和0.34 ns。较低的RMS值表明，平滑的UCV结果接近PPP结果。TL-PTB，TL-USNO和USNO-PTB链接的双重差的均方根（RMS）在40 d期间分别为0.29 ns，0.38 ns和0.34 ns。较低的RMS值表明，平滑的UCV结果接近PPP结果。
