Date Time Component Description
05/23/200714:55:00 Termination of NOAA-14 mission
05/16/200714:40:00 Loads news ESA biases and scale factors. Begins safety macro Disables memory checksumming
10/05/200619:15:00 Return to Bus-B and re-enable bus switching Return to Nominal attitude mode Clear DFS overflow and Lvl9 error counts Re-enable IMU switching
08/10/200617:55:00 Plays back GAC recording, re-enables redundancy management actions, removes CDTBL changes.
08/10/200614:47:00 Pitch maneuver setup, reconfigures CDTBL, disables much redundancy management, begins maneuver macro
