Abstract:A time transfer experiment based on the BDS precise point positioning (BDS PPP) technique is carried out using WHU (Wuhan University) 5 min precise satellite clock products. Experimental data come from the observations of four stations that belong to Gansu continuously operation reference station system. In order to verify the accuracy of time transfer based on BDS carrier phase (BDS CP), this paper compares the difference between BDS CP results and GPS CP results. The experimental results demonstrate that the RMS of the difference between BDS CP and GPS CP is about ±0055 ns. Since the accuracy of time transfer based on GPS CP is up to 0.1~0.2 ns, it can be inferred that the accuracy of time transfer based on BDS CP is roughly equal to GPS CP.
