Data Capture:&nbsp; 100%&nbsp; DOY 306-312 2010<br><br>
&nbsp;<br><br>
NOAA Space Weather Prediction Center does not have a backup
antenna.<br><br>
NOAA SWPC currently has antenna time with NICT (Japan), DLR
(Germany),<br><br>
and Wallops (Virginia).&nbsp; This week, NICT will be down from
11/12-11/13<br><br>
for maintenance.&nbsp; 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.&nbsp; 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>

Anomalies:<br><br>
&nbsp;<br><br>
DOY 306&nbsp; 11/02/2010&nbsp; S-ACE-0553&nbsp; G10-0069&nbsp;
ace_pass.proc did not finish<br><br>
Nominal end of track notification not received.&nbsp; 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:&nbsp; Manual intervention required.&nbsp; Pass Summary and Clock
Calibration <br><br>
Report manually generated.&nbsp; <br><br>
&nbsp;<br><br>
DOY 309&nbsp; 11/05/2010&nbsp; S-ACE-0554&nbsp; G10-0070&nbsp; 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.&nbsp; The FOT manually disconnected
and <br><br>
re-established an active realtime telemetry bind.&nbsp; MMOC began
receiving telemetry. <br><br>
IMPACT:&nbsp; Manual intervention required.&nbsp; All data recovered
during subsequent support.<br><br>
&nbsp;<br><br>
NOTE, WIND anomaly reports will be included when problems with
MMOC<br><br>
software/equipment would have impacted ACE operations.<br><br>
&nbsp;<br><br>
DOY 309&nbsp; 11/05/2010&nbsp; S-WIND-0477&nbsp;&nbsp; TTC V10.1 SW DCD
PIT test with D54 unsuccessful<br><br>
Tracking, Telemetry, &amp; Command (TTC) V10.1 SW Data Capture &amp;
Deliver (DCD) Project Interface Test (PIT) with D54 unsuccessful.&nbsp;
MMOCOPS1P (primary) was configured for the RNS from 10/309/1450-1650
(Committed).&nbsp; 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.&nbsp; 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>
&nbsp;<br><br>
Note, both Wind and ACE had the same BOT on DOY 309.<br><br>
