Table 3 Mean and STD of the difference between the time transfer solutions calculated from BDS-3 and BDS-3/GPS PPP in Scheme 1 and Scheme 2 (ns) and the PPP time transfer with IGS final products. Note that (%) indicates the improvement of Scheme 2 compared to Scheme 1 for the STD values

From: A new receiver clock model to enhance BDS-3 real-time PPP time transfer with the PPP-B2b service
