In 2020, users in and around China had access to a new real‐time precise point positioning (RTPPP) service with the BeiDou global navigation satellite system (BDS‐3) B2b (PPP‐B2b) signal. In this study, the quality of PPP‐B2b products is first assessed and compared with the CNAV1 broadcast ephemeris. Then a mode of BDS‐3 PPP time transfer with PPP‐B2b (
