Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg28 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 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: APSG28 Description APSG Scheduler: NASA Correlator: WASH Start: 2011-201-18:00:00 End: 2011-202-18:00:00 Current yyyyddd: 2011201 (2011.55) ( 15763 MJD, WED. 20JUL.)
