| Summary: | Global Navigation Satellite System (GNSS) Precise point positioning (GNSS PPP) is widely applied in high precision international time transfer. With the development of GNSS precision orbit and clock products, GNSS time transfer technology has also attracted the attention of researchers. Traditional PPP has a long convergence time. In this paper, the improved algorithm based on the RTS method is used to calculate the time transfer results of different navigation systems to evaluate the improvement of this method on the time transfer results of different systems. The results show that the time transfer link based on Global Positioning System (GPS) and BeiDou Navigation Satellite System (BDS) can both achieve sub-nanosecond precision. The frequency stability of the time transfer results can reach 2E-14 with the average time of 1E6 seconds. The improved method can effectively reduce the influence of the convergence of the forward filter on the time transfer results. |
