Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg35 Prepared by C. Thomas, NVI, Inc./GSFC =========================================================== The primary purpose of this Asian Pacific Space Geodynamics (APSG) session is to continue monitoring the relative motions of the plates in the Asia-Pacific region. This session involves fourteen (14) sites on five (5) plates. Aira, Kunming, Seshan, and Urumqi are on the Eurasian plate. Chich10 is on the Philippine Sea plate. Hobart-12m, Katherine, Warkworth, and Yarragadee are on the Australian plate. Kashima-34m, Kashima-11m, Koganei, and Tsukuba are on the North America plate. Kokee is on the Pacific plate. Thus, this session will produce critical data for the investigation of the current crustal motions in the Asia-Pacific region combined with the data from the APSG SLR and GPS campaigns. Also, this experiment will improve the accuracy of the geocentric coordinates of the participating stations. =========================================================== ----- Parameter listing -------------------------------------- Experiment: APSG35 Description APSG Scheduler: NASA Correlator: WASH Start: 2014-342-16:30:00 End: 2014-343-16:30:00 Current yyyyddd: 2014342 (2014.94) ( 17000 MJD, MON. 8DEC.)
