Modelling and Assessment of Single-Frequency PPP Time Transfer with BDS-3 B1I and B1C Observations
Remote Sensing, 2022 BDS-3 is now providing global positioning, navigation and timing (PNT) services. BDS-3 has new B1C, B2a and B2b signals compared to BDS-2. This work presents two single-frequency (SF) PPP time transfer models using BDS-3, B1C and B1I observations, and ...

Improving the day-boundary discontinuities in BDS-3 carrier-phase time and frequency transfer
Geo-spatial Information ScienceThe BeiDou global satellite navigation system (BDS) is an important tool for precise remote time and frequency transfer. The current day-boundary discontinuity in the data process of the BDS-3 carrier phase (CP) time transfer limits the exploitation of ...
