Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg18 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 five sites on the three plates. Hobart and Parkes are on the Australian Plate, Urumqi and Tsukuba 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, especially Urumqi. =========================================================== Parameter values for experiment APSG19 Experiment description: APSG Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2006-283-17:30:00 Nominal end: 2006-284-17:30:00 Current yyyyddd: 2006283 (2006.78) ( 14019 MJD, TUES 10OCT.)
