The receiver clock model enhances BDS-3 real-time PPP one-way timing
Aiming at the problem of re-convergence caused by short data anomalies in real-time precise point positioning(PPP)one-way timing,the receiver clock offset in PPP according to the high stability characteristics of the station clock was proposed.Four stations connected to a high-precision atomic clock for 15 consecutive days were chosen and real-time precise products from BDS-3 PPP-B2b service were selected to analyze the influence of the clock model on real-time BDS-3 PPP one-way timing.The experimental results show that the clock model can effectively avoid the problem of re-convergence in the case of short-time anomalies,and can increase the real-time BDS-3 PPP timing uncertainty by up to 22%and the frequency stability by up to 75%.
