Space Res., 45(12), 1470-1480 DOI: 10.1016/j.asr.2009.09.019 Changes in data processing: #week 1568: goa-test.2010.03.25b Use Bulletin-A as a priori instead of Bulletin-B #week 1574: goa-test.2010.03.31e Same executable but with /DEV scripts (all official version) #week 1579: goa-test.2010.04.28a Same executable without any DEV scripts #week 1580: goa-test.2010.05.25h Major change affecting solar array orientation for SPOT5 after Jan 2008 see details in Gobinddass et al., Adv. Space Res., 2009 #week 1597: goa-test.2010.09.20c More recent version, close to future 6.0 official version for tests #week 1599: goa-test.2010.05.25h Back to previous test version #week 1606: goa-6.0 Latest JPL official version #week 1487: goa-test-2011.03.17b Including Jason-2 and Cryosat-2 data deleting stations in the South Atlantic Anomaly (SAA) for SPOT-5 reprocessing done for weeks: 736-738 + 955-995 + 1124-1131 + 1487-1619 #week 1632: goa-test-2011.05.11b Minor change (deleting unecessary files) #week 1649: correct bug in estimating CRYOSAT2 drag Estimating every hour in the multi-satellite mode (instead of previously once per day) also estimate CONST_L terms for TOPEX and JASON2 every 8 hours (instead of previously once per day) #week 1656: test.2011.09.27c Minor change: do not use DEV scripts anymore 4) Global Statistics ==================== GPS week number 1691 from 03-06-2012 to 09-06-2012 Total number of stations = 50 Total number of satellites = 4 Combinations
