On 15-18th, Oct, Chang Hua and Li Chenghong attend the annual meeting of Chinese Geoscience Union (CGU) held in Beijing International Convention Center. They attend Session 49: "Modern GNSS Data and Technology And Its Application In Geoscience". Chang gives a talk on "Combine GNSS with accelerometer data and recent study of Multi-GNSS PPP". Li gives a talk on "Integration of GNSS and Strong-motion records and its application to earthquake monitoring in the near-field".

These two talks arouse the interest of the audience, especially whose work or research field are concerned with "Earthquakes". The development of GNSS real-time PPP as well as the integration of GNSS and accelerometer data has made GNSS applicable to earthquake monitoring in the near-field.
