Abstract Aimed at the vast network data of IGS, MGEX and iGMAS, a rapid data processing method of multi-GNSS zero-difference precise orbit determination is proposed. Then, the accuracy and time consumption of the ultra rapid orbit products are analyzed. The results show that the efficiency of data processing using multi-GNSS ultra rapid orbit products is obviously improved. It provides enough time for data generation and downloading, because less solving time is needed. Thus, the 24 h observation data can wholly participate in orbit determination, and the orbit determination accuracy of each satellite system is also improved to some degree
