Researchers from the Time Keeping Laboratory, of the National Time Service Center of the Chinese Academy of Sciences analyzed the time transfer performance of the BDS-3 signals. The results indicate that the time transfer performance of the BDS-3 satellites is over 50% higher than that of the BDS-2 satellites. In terms of the common view time comparison, the standard deviations of the zero-baseline common clock time comparison of the new BDS-3 signals are comparable to that of GPS and Galileo.
To evaluate the time transfer performance of BDS-3, the pseudorange measurement noise, precision of conventional common view (CV) and all-in-view (AV) time comparison and the instability of the precise point positioning (PPP) time transfer were analyzed. The results were published in the journal Metrologia.
