Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg31 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 ten sites on the three plates. Katherine is on the Australian Plate, Seshan, Urumqi, Tsukuba, Chich10, Aira, Kashima-11m, Koganei, and Sintotu3 are on the Eurasian Plate, and 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: APSG31 Description APSG Scheduler: NASA Correlator: WASH Start: 2012-283-16:30:00 End: 2012-284-16:30:00 Current yyyyddd: 2012283 (2012.78) ( 16210 MJD, TUES 9OCT.)
