| الوصف: | At present, the space-borne atomic clocks carried by major global satellite navigation systems mainly include rubidium atomic clocks, hydrogen atomic clocks and cesium atomic clocks. Compared with BDS-2, one of the important changes of BDS-3 is the application of new domestic space-borne rubidium atomic clocks and hydrogen atomic clocks. Since BDS-3 was officially put into operation, large amounts of data have been accumulated. In this paper, two years of precise clock offset data is used to verify the on-orbit performance of the new domestic atomic clock. And the performances are compared with the mainstream space-borne atomic clocks of GNSS. The long term variation characteristic of BDS-3 atomic clocks are analyzed. It's showed the BDS-3 hydrogen atomic clocks have a smaller drift rate and better stability which close to the performance of Galileo clock, and the performance of onboard rubidium atomic clocks of BDS-3 is improving continually which is up to the world advance level. |
