摘要：The accuracy of precision point position (PPP) time transfer can achieve a value below 0.3 ns. Time transfer by precise point positioning has the defect of long latency resulting from IGS products, and cannot satisfied for the high real-tine user. A real-time precise point positioning time transfer algorithm using IGS products is proposed, which can improve the real-time, the feasibility of the algorithm is tested and verified in this paper. The time transfer results show that the accuracy of the new algorithm can be reach to 0.30 ns for RMS and 0.25 ns for STD. Moreover, the daily stability of the time transfer results is up to 2E-15. Experiments show that, the algorithm is real-time, and the time transfer results are coincident with IGS final clock products well.
