**COMMENTS/CHANGES:**

NOAA-11 No changes since previous report.

NOAA-12. In analyzing a larger than usual data set on N12, 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 two array moves to --45
degree offset. Therefore, Andy will oversee an additional move of the
N12 offset to --60 degree offset scheduled for Weds, 30 July.
Furthermore, 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 AVHRR scan motor current continued to improve during the
past week as it has for the past 8 weeks. Recently it

has begun to fluctuate in what could be considered nominal values.
Current images from N14 show good to poor image quality.

NOAA-15: Svalbard unencrypted command tests using STX-4 were performed
each day from 21 through 25 July. In general these

tests were very successful with Svalbard proving their ability to
command the POES spacecraft in clear mode using

NOOP commands from both antenna 1 and 2. Some difficulties in the timing
of commanding (between the Fairbanks CDA and Svalbard) were encountered
but overall the concept objective was achieved.

NOAA-16: EMOSS ADACS engineer Jim Sheperd chaired a "Gyro Summit"
between NOAA, NASA and Lockheed engineers on

24 July because of concerns about the performance of N16's gyro
characteristics. The primary topics discussed at this meeting were as
follows:

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.)

Primary action items originating from the meeting included the
following:

> 1\) Swap N16 gyro channel assignments. This was done Tuesday, 29 July
> at 14:30Z: The previous N16 gyro
>
> assignments were: Gyro-2: Z/Pitch on chan-B, Gyro-3: X/Yaw and Y/Roll
> on chan-B, Gyro-1: not used

The new gyro assignments are now: Gyro-1: Z/Pitch and Y/Roll on chan-A
Gyro 3, X/Yaw on chan-A,

Gyro-2 deselected. Jim Sheperd oversaw this operation.

2)  Study the effects of the DMSP Rgyro software test and determine the
    implications on a proposed N15

Rgyro software test. The analysis report on this DMSP operation is due
to EMOSS engineer Jim

Sheperd by 8 August. Nodal analysis review per POES will be undertaken.

3)  Generate a draft N16 Rgyro test plan for N15 by 18 August with a
    test implementation date sometime in

> the Fall of 2003 after the NOAA-N end to end test..

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

polar region will be triggered 28 July. The next triggering of this
macro is expected to be 1 August.

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.

NOAA-N Level 2 Data base validation (Phase One) was completed by the
EMOSS team and delivered to NASA as scheduled (25

July) for their review despite some difficulties experienced with
performing the process on the Dev Rail. 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
in the coming days. Phase Two data base validation will require CWS and
PACS upgrades to be complete before being implemented. On 24 July EMOSS
POC's Azi Dinat and Jeff Devine met with the NOAA software managers to
discuss methods by which to improve the efficiency of data base
generation and distribution using the Dev Rail a number of process
improvements originated from this meeting including improving
coordination among Dev Rail users with via a more robust "scheduling
mechanism" and adding another disk to the Dev Rail to serve as a "work
in progress" area from which finished products can be copied to the Base
area which will serve as the area that provides configuration controlled
copies of each product.

Misc: EMOSS engineer Jim Walters is supporting the MHS pre flight model
hand over review in Sunnyvale CA between 28

and 30 July. A trip report will be generated by Jim regarding the
highlights of this meeting and attached to a future weekly report.
