SOT Shift Report 2002-07-16 M1090 Shift M1090 Duration: 16 Jul 2002 17:05 EDT - 16 Jul 2002 21:30 EDT 16 Jul 2002 21:05 GMT - 17 Jul 2002 01:30 GMT SOT Lead: Tom Aldcroft Spacecraft/Aspect: FOT/Science Liason: HRC: ACIS: ======================================== Plan ---- Uplink software patch to install new IRU calibration coefficients and perform initial checkout. Events ------ 21:29 Uplink patch file OBCA_157_PR146.CLD 23:00 Complete first post-patch manuever (135 degrees), acquire all stars Notes/Issues/Problems --------------------- - ACE radiation rates are moderate but leveling off - First 3 maneuvers show that the new IRU calibration coefficients have the desired effect of reducing one-shot attitude update errors. In each case the observed attitude update was well within 30 arcsec of the predicted update. In particular, the third manuever would have had a very large offset (> 100 arcsec) using the old coefficients. - A total of 5 more maneuvers will be performed over the next several hours to complete the verification.
