**COMMENTS/CHANGES:**

NOAA-11 No changes since previous report.

NOAA-12. For the first time in almost 2 years, a data set of greater
than 24 continuous hours was obtained for N12 thereby

allowing more in-depth analysis of that spacecraft. In analyzing this
data, EMOSS power engineer Andy Miller has noticed a significant number
of small surges in bus voltage that is indicative of continued shunt
stress which motivated the recent previous 2 array moves to --45 degree
offset. Therefore, Andy is proposing that an additional adjustment to
--60 degree offset be considered sometime in the near future and is
awaiting a approval by NOAA management before implementing this next
move. Whether approved or not, at the beginning of October the sun angle
(relative to the array position) will begin to shade the sun sensor and
the array will have to moved again to a position of --30 degree offset
for the duration of that month.

NOAA-14: N14's power situation remained nominal throughout the past
reporting period and the spacecraft continues to have a

good power balance since the solar array adjustments last month.

N14 AVHRR scan motor current continued to improve during the past week
as it has for the past 7 weeks and is approaching what could be
considered nominal values where imagery should be of sustained high
quality. (Illustration 1). No AVHRR images were available at the time
this report was generated and so none are included in this report.

NOAA-15: Preparation for Svalbard unencrypted command tests using STX-4
were initiated from 18-20 July by powering up

STX-4 (illustration 2) and switching the N15 spacecraft into unencrypted
mode (out of stored commands) for one orbit per day using stored
commands. On 21 July, during 2 overlapping Fairbanks/Svalbard
visibilities starting at 20:00Z the actual tests with Svalbard began. On
the first pass, Fairbanks ran CP DECRYPTF per SCR 116 to configure
spacecraft and PACS for clear mode then turned over command authority
over to Svalbard. Svalbard successfully achieved command carrier lock
with acceptable AGC levels but the Last Command Time was reached before
any NOOOPS were transmitted by them and the spacecraft faded in clear
mode. On the second pass at 21:35Z, the spacecraft rose in clear mode
and, for the first time, Svalbard successfully unlinked a NOOOP command
in the clear mode. After Svalbard commanding was complete, command
authority was given back to Fairbanks who to successfully commanded the
spacecraft back to encrypted mode. This operation will be repeated each
day at approximately the same time until 25 July in order to support
METOP operational preparations. Angelique Riley is EMOSS POC for these
operations.

The N15 AMSU-B motor current, AVHRR scan motor current and HIRS filter
motor current were all nominal during

the past week with no new surges. (illustration 3).

NOAA-16: The macro developed by EMOSS engineer Jon Woodward to switch
the AVHRR to Channel 3A over the northern

polar region was successfully trigger twice in the past week; first on
19 July from 17:52 to 18:04Z and again on 21 July from 22:30 to 22:46Z
(illustration 4). Additional triggerings of this macro (always via
realtime command at dates and times specified by Dr Xianggian Wu. The
next triggering is expected to be on or about 30 July.

Yaw update values were generally nominal during the past week
(illustration 5). However, the trend of the gyros and

IMU towards less than perfectly nominal performance remains a cause for
concern. Therefore, a "summit meeting" has been called for 24 July at
13:00 eastern time in the LCR Team Room at Suitland to discuss the
following issues:

1\. NOAA-16 IMU performance, and related issues, plans for configuration
changes

2\. Plans for RGYRO testing and requirements/preparations for conducting
the test

3\. Other related concerns with this series IMU (NOAA-15, DMSP, etc.).

This meeting will be chaired by EMOSS engineer Jim Sheperd and is open
(via teleconference) to any interested party. who can dial in by calling
301-817-4220 (or just 2000 if located at Suitland), wait for a dial
tone, followed by 2 short beeps then Enter 1016\* and then enter 1234#
If connected, 2 beeps indicates you are on the meet-me net

NOAA-17: RF testing continues at Svaalbard. These tests dump GAC data
over the Svaalbard site once or twice a day using a

variable combination of S-band transmitters and frequencies (often
STX-4). These tests are being conducted to validate the Svaalbard ground
station capabilities ability to support METOP and will continue out of
the schedule until August 23rd. STX-4 appears to be performing in a
nominal manner (illustration 6).

NOAA-N Level 2 Data base validation (Phase One) has been completed by
the EMOSS team and delivery to NASA for their

review is expected to be on time (25 July). A schedule for TTS time
during the month of August when NASA and EMOSS engineers can review the
data base to a Level 3 (Phase One) is being generated and will be
distributed within the next week. Phase Two data base validation will
require CWS and PACS upgrades to be complete before being implemented.
Azi Dianat has been the EMOSS POC for all data base development efforts.

EMOSS engineers and management attended a CWS implementation meeting
with NOAA management to determine the best method for ensuring that
NOAA-N launches using the CWS (vs 3100) system. A plan for functional
testing, parallel operations, operational training and CWS primary
operations was worked out by this group but all such processes are
predicated on the timely receipt of a baseline CWS by the EMOSS team.

EMOSS is planning on sending an engineer to support the MHS pre flight
model hand over review in Sunnyvale CA between 28 and 30 July. An EMOSSS
POC has yet to be designated but will be either Tina Baucom or Jim
Walters. .
