Session Notes for APSG (Asian Pacific Space Geodynamics) session: apsg29 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. 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: APSG29 Description APSG Scheduler: NASA Correlator: WASH Start: 2011-229-18:00:00 End: 2011-230-18:00:00 Current yyyyddd: 2011229 (2011.63) ( 15791 MJD, WED. 17AUG.)
