摘要	The experimental satellite of the third generation BeiDou navigation satellite system (BDS-3e) is a significant step towards expanding the current regional BDS-2 into a global satellite navigation system. These satellites are equipped with new atomic clocks and the application of time and frequency transfer is therefore important. In this study, carrier phase observations from BDS-3e and BDS-2 satellites were employed in time and frequency transfer. Experiments with two schemes were designed to assess the time and frequency transfer performance. BDS-3e increased the number of available satellites, and the corresponding time dilution of precision (TDOP) was improved. Therefore, the accuracy of receiver clock offset is improved, and the noise level of time links with BDS-3e is also improved compared to using only the BDS-2 constellation. The range was 4.2% for the CEDU-KAT1 time link. However, because fewer satellites are available and the corresponding accuracy of satellite tracking geometry is low for the HOB2-KAT1 time link, the above-mentioned improvement was not apparent. In terms of the frequency stability, the CEDU-KAT1 time link using the BDS-3 solution showed an improvement of approximately 12.3% compared to using only the BDS-2 solution when the averaging time intervals were within 1000 s.
