Abstract:
To provide high-precision timing services of the BeiDou Navigation Satellite System (BDS), this work performs a detailed investigation of integrated BDS-3 and BDS-2 real-time precise point positioning (PPP) time transfer with the ultrarapid products. Compared with the final precise clock products, the average standard deviation (STD) of estimated BDS-3 MEO/IGSO satellites is 0.1 ns, while the corresponding value of BDS-2 is 0.2 ns. The precision of real-time BDS-3/2 PPP time transfer can achieve better than 0.5 ns. The phenomenon of reconvergence and abnormal jumps in receiver clock series can be effectively reduced because of the evenly distributed MEO satellites.
