Abstract: Navigation satellite real time orbit determination and clock determination are research highlights in navigation areas. The processing strategies and processes for Beidou Navigation Satellite System (BDS) real time orbit determination and clock determination were provided，especially for the clock processing with zero-differenced absolute clock and epoch-differenced relative clock. Using the data from the Multi-GNSS Experiment (MGEX) and international GNSS monitoring & Assessment Service (iGMAS) tracking networks，the average orbit accuracy for real time BDS in radial direction is better than 20cm，and 10cm for GEO，IGSO and MEO，respectively. And the clock accuracy for real time BDS can reach 0.5~4.5 ns，and 0.2~2.0 ns for GEO，IGSO and MEO，respectively. Based on the this result，the real time precise pointing position (PPP) performance following BDS can achieve decimeter level.
