ACE Weekly 10/08/04 - 10/14/04

All ACE spacecraft subsystems are performing nominally.  An attitude 
maneuver was successfully  executed on 10/08/04.  The next attitude 
maneuver is scheduled for 10/21/04.

============================================================================
Orbit Events:

The next SEZ crossing will occur in the Nov-Dec time frame.

=====================================================================
OCRs Executed:

None

=====================================================================
Ongoing Activities:

TAPS:

- TAPS Release 4.3 was installed on the Prime System on 10/13/04.
   -- FOT regression testing is in progress.

----------------------------------------------------------------------------
Automation (ROBOTT):

- ROBOTTv0.9 delivered to String 1 on 09/27/03 (OCR GND_145).
   --  Performing operations in "Auto" mode on String 1.
   -- 13 DR fixes in this release.
         --- 12 DRs have been verified by the FOT to date.
           ---  The last DR to be verified will require ROBOTT to be 
observed over a period
                 of time to ensure no reoccurrence of the problem.
   --  8 DRs have been written against this release.

Anomalies:

DOY 04282 (10/08/04) ACE Anomaly G04-0117 - MAD 26m (DSS-66) Late AOS
At BOT (13:00) DSS-66 did not have telemetry online to the MOC.  At 13:02 
DSS-66 informed FOT that they would be 10 minutes late in bringing the 
antenna up.  At 13:09:20 DSS-66 put telemetry online to the 
FOT.  IMPACT:  BOT was delayed by 9 min 20 sec.  Delayed pass 
activities.  DR# M102784

DOY 04283 (10/09/04) ACE Anomaly G04-0118 - GDS 26m (DSS-16) Command Problems
First command sent to the S/C didn't reach it due to command mod index 
problem at station.  Station executed workaround noted in CAD-MON-MCP-416 
and command capability was restored.  IMPACT:  No command capability for 
3min 35sec.  DR# G104864

DOY 04284 (10/10/04) ACE Anomaly G04-0119 - Data Spikes in TAPS Report
Data spikes were seen in the Daily Activity report.   The TAPS 
decommutation process is skipping a packet that is partially located at the 
end of the chunk which is read from the data file.  There is a problem with 
parsing data in that partial packet for mnemonics that have a byte offset 
between 642 and 645.  IMPACT:  Reports utilizing that particular data will 
be suspect.  DR CDSID 00021044
