APSG 2015 International Symposium of Asia-Pacific Space Geodynamics (APSG) Program, was successfully held in Moscow, capital of the Russian Federation, 24-28 August, 2015.

Shanghai Astronomical Observatory, Chinese Academy of Sciences is one of the organizers as well as the APSG Program initiator. Other sponsors are: APSG Program Central Bureau, Institute of Astronomy of RAS, Geophysical Service of RAS, Institute of Geodesy & Geophysics of CAS, Institute of Applied Astronomy of RAS. As many as 80 participants of experts, researchers and students from several countries and regions including Russia, China, America, Australia Uzbekistan, Taiwan and Hongkong attended the symposium, communicating latest progress on Asia-Pacific Space Geodynamics.

The conference on Geodetic Datum and Regional and Terrestrial Reference Frame Realization, with altogether 48 oral and 8 poster presentations, covers such sessions as space geodesy techniques and progresses, terrestrial reference frame realization, Earth gravitational field and height datum, regional crustal structure movement, coseismic and postseismic crustal deformation, tsunami and volcanic activities.

Our group of 10, including Professor Huang Cheng and Professor Huang Chengli attended the conference and made 7 oral and 1 poster presentations like“Progress on Asia-Pacific Space Geodynamics (APSG) Project”and“Constraint on the Earth Density Near Core-mantle Boundary by Free Core Nutation.” In addition, Huang Cheng and Huang Chengli worked as conveners as well.

Plans for APSG’s future are also discussed and six resolutions are made in the symposium, such as APSG Resolution on the Global Geodetic Observing System and Resolution on applying real time and augumentation system of GNSS to the Tsunami and large mega-thrust earthquakes early warning system, which will surely make contributions to leading APSG Project to a sounder and maturer future. Meanwhile, it can not only deepen our understanding of space geodesy, astro-geodynamics theories and techniques, and latest progress on monitoring the earth movement, but also expand our vision of the moon and planets exploration, which will enormously speed the development of astro-geodynamics research.
