Abstract
Time transfer by precise point positioning has the defect of long latency resulting from IGR products. GPS common-view can be updated once every 16 min, but with a precision of about 3–5 ns. A real-time precise point positioning time transfer algorithm using IGS RTS (Real-time Service) products was proposed. It was proved to be practical through the time transfer experiments among 4 time laboratories in Western Europe. 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 stability of the time transfer results is up to 2E−15 at 1 day averaging.
