Abstract EN
The time model of Beidou satellite clocks is analyzed.
The general relations of satellite clocks with the system time are studied.
The error sources of two-way radio time transfer between satellites and uplink stations are analyzed.
The uncertainty of type A is about 0.3 ns in Beidou system.
All the satellite clocks in orbit of Beidou satellite navigation system are evaluated by the clock offsets observed by the two-way radio time transfer.
The frequency stabilities at a sample time of 10000 s and 1 day for all the satellite clocks are better than 1.0×10-13.
It means that the performance of Beidou satellite clocks in orbit is consistent with the ground test, and the results in orbit are a little better than those in ground vacuum.
