This week, NICT will be down from 11/12-11/13<br><br> for maintenance. The network connection to the Air Force Satellite <br><br> Control Network (AFSCN) was lost on September 1, 2010 with the<br><br> closing of the Onizuka Air Force Base. There are plans to add a network<br><br> through Vandenberg Air Force Base, but that has not been implemented.<br><br> Note, the NOAA SWPC operations is separate from the Goddard flight<br><br> operations, but this information is worth noting and therefore included<br><br> in this weekly report.<br><br> <br><br> ========================================================================<br> <br> Anomalies:<br><br> <br><br> DOY 306 11/02/2010 S-ACE-0553 G10-0069 ace_pass.proc did not finish<br><br> Nominal end of track notification not received. FOT manually exited <br><br> ace_pass procedure and performed necessary clean up activities prior to <br><br> configuring system for DOY 307 pass activities.<br><br> IMPACT: Manual intervention required. Pass Summary and Clock Calibration <br><br> Report manually generated. <br><br> <br><br> DOY 309 11/05/2010 S-ACE-0554 G10-0070 Telemetry delayed 60 minutes at BOT<br><br> Although MUS reported active binds and JPL stated there were no problems, <br><br> telemetry was not reaching the MOC. The FOT manually disconnected and <br><br> re-established an active realtime telemetry bind. MMOC began receiving telemetry. <br><br> IMPACT: Manual intervention required. All data recovered during subsequent support.<br><br> <br><br> NOTE, WIND anomaly reports will be included when problems with MMOC<br><br> software/equipment would have impacted ACE operations.<br><br> <br><br> DOY 309 11/05/2010 S-WIND-0477 TTC V10.1 SW DCD PIT test with D54 unsuccessful<br><br> Tracking, Telemetry, & Command (TTC) V10.1 SW Data Capture & Deliver (DCD) Project Interface Test (PIT) with D54 unsuccessful. MMOCOPS1P (primary) was configured for the RNS from 10/309/1450-1650 (Committed). MMOCOPS1B (backup) was configured for the DCD from 10/309/1450-1650 (Non-committed). Received telemetry on MMOCOPS1P. Able to bind on MMOCOPS1B but did not received telemetry from the test SLE telemetry server. Wind was up at the same time as ACE and they also did not receive telemetry for quite some time. Not sure if it's related.<br><br> <br><br> Note, both Wind and ACE had the same BOT on DOY 309.<br><br> <br><br> ==============================================================<br><br> Jacqueline Maldonado Snell<br><br> Advanced Composition Explorer Flight Operations Team Manager<br><br> Honeywell Technology Solutions Incorporated (HTSI)<br><br> Goddard Space Flight Center<br><br> Bldg. 14 Rm W10B, Mailstop 428.2<br><br> Greenbelt, MD 20771<br><br> Phone: (301) 286-7072 <br><br> Fax: (301) 286-1729 <br><br> E-mail: <a href="mailto:Jacqueline.M.Snell@nasa.gov"> Jacqueline.M.Snell@nasa.gov</a><br><br> <x-sigsep><p></x-sigsep> **************************************************************************<br> Andrew J.
