**COMMENTS/CHANGES:**

NOAA-12 No change from last week. N12 supports continued to be minimal
(only two passes between the previous weeks report

and this one) although they have been increased to an average of one per
day in the coming week. Now that eclipse season has ended, EMOSS power
engineer Carl Gliniak will be making a recommendation on whether or not
turning on failed payloads for use as resisters will enhance the N12
power balance situation.

The VHF-RF conflict between N12 and N15 ended on 30 Aug although there
was no changes to N12 as a result of this event.

NOAA-14: No changes since previous report. AVHRR imagery and health
remains nominal (illustrations 1&2) as does power

balance (illustration 3). VTX-2 (APT) remains off until TBD because of
an RF conflict with N17.

NOAA-15: The N15 spacecraft is currently in a thermal downtrend. The N15
AMSU's were nominal during the past week (illustration 4) while the
AVHRR actually improved as it got cooler (illustration 5) and the HIRS
remained the same, completely nominal (illustration 6).

EMOSS engineers continue monitoring the gyro-1 current on N15 a little
more closely as some small instabilities increased the gyro-1 current
value to higher than preferred values (although still below yellow high,
illustration 7). Jim Sheperd is POC.

EMOSS engineer Carl Gliniak will over see an operation that will dwell
(normal dwell, not high speed) on the solar array deploy value (NSADPLY)
for 2 orbits on 30 Aug starting at 14:30z. This operation is being
conducted at the request of NASA engineers who are investigating the N18
pitch oscillation TOAR and the data will be compared to that generated
by the other spacecraft (N18, 17 and 16) which also experienced this
same operational test.

The N15 APT data stream was turned back on today, 30 Aug at
approximately 07:00z out of stored commands when VTX-1 was turned back
on after being off since the end of July because of an RF conflict with
N12. The transmitter turnon executed without incident and is currently
performing nominally (illustration 8). There could be some changes to
the thermal profiles of some N15 components as a result of this turnon
although nothing that should be cause for concern. Will Chadwick was
EMOSS POC for this operation.

NOAA-16: The N16 AVHRR scan motor improved and stabilized (albeit at
higher than desired values) during the past week

(illustration 9). The most notable area of improvement was with synch
delta which has started to show a decreased tendency to "max out"
immediately following its rephase each orbit over the South Pole
(illustration 10). Furthermore as of 30 Aug, for the first time in at
least two months, the MIRP rephase enable operation over the South Pole
each orbit is NOT resulting in an actual MIRP rephase (with its
resultant loss of data; illustration 11). In addition, imagery, which
had been exhibiting bar codes early in the week, has cleared up since 25
Aug with no bar codes appearing since that day. Conversely, the scan
motor current does remain elevated and wave patterns continue to persist
in HRPT images (illustration 11b.) The AVHRR TCE (24) remains off.

The N16 HIRS is also showing slightly less stability as its high vs. low
range has increased and remained at or near its widest value ever, as it
has since mid-summer. However, the HIRS filter motor current, filter
motor temperature, filter wheel synch and filter wheel period monitor
all remain within nominal values at the current time (illustration 12).

On 30 Aug at 00:30z, the N16 STX assignments were changed in conjunction
with changes made to the N18 STX assignments as that spacecraft became
operational and N16 is now designated a "secondary PM spacecraft". The
change in the STX assignments was that STX-1, which had been the HRPT
transmitter was switched to a playback transmitter while STX-2, which
had been used for playbacks was re-assigned as the new HRPT transmitter.
This switch occurred out of stored commands and both transmitters appear
to be performing nominally (illustration 13). In addition to changes in
STX assignments, N16 switched its Beacon transmitter assignment with #1,
which had been active being turned off and #2 which had been inactive
being turned on. This reconfiguration was also conducted as part of the
N18 activation to primary PM spacecraft (and N16's downgrade to
secondary). The operation completed nominally and the BTX-2 is
performing the same way. Will Chadwick is EMOSS POC.

N16 ADACS was generally nominal during the past week although some earth
sensor "instabilities" have recently been introduced as a result of
sun-moon incursions (illustration 14) that will continue for at least
several days. This situation is common with N16 and is not a reason for
concern at this time.

NOAA-17: There were no changes from last week. The remaining N17 AMSU's,
the AVHRR and HIRS were all nominal and

stable during the past week (illustration 15 through 17). In addition,
the gyros on N17, which had recently shown some tendencies toward
instability stabilized during the past week (illustration 18).
Regardless, both the gyros on N17 are operating at, or near all time
highs and increased vigilance over them will be maintained by EMOSS into
the foreseeable future. Jim Sheperd is EMOSS POC for this subsystem.

NOAA-18: N18 is officially operational as of 30Aug at 00:30. As the
first reconfiguration for this newly operational spacecraft,

the HRPT and Beacon assignments were changed on 30 Aug at 07:30z out of
stored commands. The STX assignments

(along with those on N16) were changed for N18 in the following manner:
STX-3 (previously HRPT) was made a playback transmitter while STX-1
(previously playback) was made the HRPT transmitter. All other N18 STX
assignments will remain as they now are. The reconfigurations completed
nominally and both transmitters are performing nominally since the
change occurred (illustration 19). In addition to STX changes, the
Beacon transmitter which had been in operation BTX-2 was operationally
replaced by BTX-1. This operational also completed nominally
(illustration 20).

The N18 payload suite performed in a nominal and stable manner during
the past week (illustrations 21-24) as did the rest of the subsystems on
N18 (illustrations 25-27). In addition, EMOSS engineers have received
reports that some (not all) of the less than nominal HIRS channels which
resulted in a TOAR been generated have been improving recently. However,
since the HIRS remains less than 100% nominal and yellow in status.

The investigation into the pitch oscillation TOAR continues. To support
this investigation, a test is currently being discussed among NOAA and
NASA engineers that will result in the N18 solar array being slewed
completely around (360 degrees) while in the dark/eclipse portion of its
orbit. If implemented, this slew will be performed twice, once in each
direction. EMOSS engineer Jon Woodward is supporting the planning stage
of this operation by identifying and preparing spacecraft macros and CPU
telemetry changes that will be necessary to support the operations.
There is no date currently identified for this operation nor has
approval yet been forthcoming from any authoritative quarter. However,
if implemented the date for such this test would probably not be any
early than two week from this week.

Discussions regarding the possible swap of N18's VTX (APT) assignment
are also underway among the engineering and scheduling divisions.
Apparently, the VTX currently in operation (#2 at 137.9125 MHZ) on N18
is often interfered with by cellular devises while orbiting over the
European continent. To alleviate this condition a swap to VTX#1 (137.1
MHZ) is under consideration. No date has yet been determined for this
reconfiguration, if it should occur.
