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.

The research team from the National Time Service Center (NTSC), Chinese Academy of Sciences (CAS), investigated the rapid convergence of BDS/GNSS real-time satellite clock estimation. To address the long convergence time of conventional methods, the team proposed a Time-Differenced Carrier Phase (TDCP)-assisted undifferenced real-time satellite clock estimation approach, significantly improving the convergence performance of BDS/GNSS real-time satellite clock products.
