Recently, a research team from the National Time Service Center (NTSC), Chinese Academy of Sciences, proposed a novel real-time Precise Point Positioning (PPP) time transfer method augmented with predicted tropospheric products derived from the Global Forecast System (GFS). The proposed approach significantly improves the convergence speed, time link precision, and short-term stability of real-time PPP time transfer, providing a new solution for high-precision time synchronization applications.

Recently, a collaborative research team from the National Time Service Center, Chinese Academy Of Sciences (NTSC) and the Nanjing Normal University proposed a real-time PPP time transfer model with tropospheric delay constraints based on Galileo HAS for improved time transfer accuracy. The proposed model can significantly improve the accuracy and stability of the time transfer results, demonstrating its potential for high-precision time transfer applications.

A research team from the National Time Service Center (NTSC), Chinese Academy of Sciences (CAS), proposed a Wavelet–LSTM model for Low Earth Orbit (LEO) satellite clock prediction, improving the prediction accuracy of LEO satellite clocks over different prediction terms.
