Performance Analysis of Real-Time PPP Based on BDS-3 PPP-B2b Service
Abstract Applying the principles of PPP and Beidou-3 PPP-B2b telegram correction model, we analyze the matching problems between two correction parameters that must be attended to in using telegram correction information for PPP. We further analyze positioning service performance in two modes, B1C+B2a and B1I+B3I, after the correction of the message information under static and imitation dynamic conditions. The results show that under static conditions, the positioning accuracy in the horizontal and elevation directions of the two positioning modes are better than 11 cm. Under dynamic conditions, the positioning accuracy in the horizontal and elevation directions are both better than 22 cm; the horizontal and elevation directions can be reached within 15 min, and do not exceed the accuracy requirements of 0.3 m and 0.6 m. The B1C+B2a combination is slightly better than the B1I+B3I combination in terms of positioning accuracy and convergence speed.
