Date Time Component Description
10/08/201314:46:46 Deactivate 3 macros that are not longer needed once thruster firing has been disabled
01/16/201316:59:10 This activates the power toggle, Macro 10, and will leave the SBUV powered, which is the upper temp macro was previously enabled for protection
01/16/201316:58:50 This deactivates Macro 13
01/16/201316:57:56 Disable Macro 4B
01/16/201316:56:34 This will load MACRO 4C to the control and non control CPU
01/16/201316:54:45 This will load MACRO 4B to the control and non control CPU
01/03/201314:13:27 Determine which macro is currently active in the toggle by reviewing the current temperature of NSBUCMTR and the macro page to see what macro is active. If macro 15 is active perform this and the following command
01/03/201314:13:00 Load the new macro 13 to both the control and no control CPU
01/03/201314:11:10 Delete the current macro 13 from the non control CPU
01/03/201314:11:02 Delete the current macro 13 from the control CPU
10/18/201116:07:53 Loads safety macros for ESTX MIMU2 test (0043 - 0046)
09/19/201114:42:58 Load safety macros for ESTX MIMU1 Test (40, 41, 42, 47)
04/17/201115:42:50 Deactivate safety macros for BYAWERR
04/16/201122:27:23 Load and activate safety macros for BYAWERR
07/15/200815:34:00 Activate CPU Macro 11 - SBUV Motor Power Toggling Under Temperature Control
07/15/200815:32:05 Load CPU Macro 14 - SBUV Motor Turn Off at 40 C, activate CPU Macro 13.
07/15/200815:30:28 Load CPU Macro 13 - SBUV Motor Toggle On at 24 C, activate CPU Macro 14.
07/15/200815:28:32 Load CPU Macro 12 - SBUV Motor Turn Off at 40 C, activate CPU Macro 11.
07/15/200815:26:39 Load CPU Macro 11 - SBUV Motor Toggle On at 21 C, activate CPU Macro 12.
12/31/200523:30:00CPU 2Substract 1.5 second (1500 msecs) from spacecraft command clock CONTROL side to compensate for leap second on 1 Jan 06 and general drift throughout the year.
12/31/200522:30:00CPU 1Substract 1.5 second (1500 msecs) from spacecraft command clock NON-CONTROL side to compensate for leap second on 1 Jan 06 and general drift throughout the year.
07/20/200519:45:00 Removes previous CPU telemetry table change on SCP 1. (Error angles were replaced with MIMU raw telemetry)
07/19/200513:30:00 Replaces Euler attitude angle errors in SCP1 cpu telemetry table 1 with MIMU raw gyro data.
06/09/200512:00:00 Operational responsibility for N18 passes to NOAA from NASA
