(GSFC-6980)" Subject: GSC SINEX Submission (gscwd25) 2014-DOY005 to 2014-DOY090 SUMMARY OF GSC DORIS SUBMISSION for 1st Quarter wd25 SINEX files July 14, 2014. This delivery consists of SINEX files in Normal equation (NEQ) from the weeks of 2014-DOY005 to 2014-DOY090. ** Special Note (1). We have updated the DORIS offset for HY2A, compared to the previous wd25 submissions. We use the following OFFSETS and CoM information for HY2A. HY2A DORIS measurement offset: (0.850, -0,750, 1.306) m (Source DORISSatellitemodels.pdf, IDS website) HY2A SLR measurement offset: (0.31126, -0.21381, 0.9944) m HY2A SLR Measurement correction: 73.7 mm (SOURCE ILRS. http://ilrs.gsfc.nasa.gov) HY2A CGMASS Values: (1.33240, 0.007, 0.0088) m (SOURCE IDS -central bureau, file HY2A satellite mass and center of gravity history file. http://cddis.gsfc.nasa.gov) ** Special Note (2). The SAA-corrected data supplied by H. Capdeville (CLS) were used for SPOT-5. #---------------------------------------------------------- 1.
