Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg30 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 eleven sites on the three plates. Hobart-12m is on the Australian Plate; Seshan, Urumqi, Tsukuba, Chich10, Aira, Kashima-11m, Koganei, Kunming, 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: APSG30 Description APSG Scheduler: NASA Correlator: WASH Start: 2012-221-18:00:00 End: 2012-222-18:00:00 Current yyyyddd: 2012221 (2012.61) ( 16148 MJD, WED. 8AUG.)
