Crustal Movement Observation Network Of China (CMONOC) is a fundamental facility which has wide-range applications in diverse areas with high precision and high spatial resolution. CMONOC network consists of GNSS, VLBI, SLR and gravity observing stations. The observation data contributes to the GNSS meteorology, plate tectonics and earthquake monitoring etc. Shanghai Astronomical Observatory (SHAO) is one of the data centers of the CMONOC network. We developed the CMONOC GNSS data processing platform and provide precise products supporting CMONOC applications. In this paper, we present the latest results from the routine data analysis. Besides the conventional results of GNSS orbits, clocks, ERPs and station coordinates etc., we present for the first time the following results: (1) regional velocity field for the 247 continuous stations, which is derived based on integrated data analysis of the CMONOC and IGS network; (2) earthquake monitoring by ionosphere disturbance analysis, which is realized by analyzing the ionosphere TEC changes time series using the quartile method; (3) earthquake monitoring by instantaneous station motion analysis, which is determined by differential 1 Hz phase observation in real-time.
