The systems team spent a significant part of the week supporting the HMI 
instrument team visit and participating in clarification discussions on a 
variety of Technical implementation and interface areas.  In addition, the 
systems team assembled and released preliminary PDR guidelines to the SDO 
team to facilitate preparation for upcoming Subsystem PDRs.  The team is 
also developing additional guidance to subsystems on PDR content and the 
peer review process that should be available for release shortly.  The SDO 
document tree is being reviewed in light of the approach subsystem and 
mission PDRs with an eye of identifying and prioritizing key mission and 
subsystem documentation needed at these upcoming PDRs.  In the area of SDO 
preliminary design work and hardware development, the SDN team delivered 
the SDN prototype to the SDO software lab this week to allow the S/W to 
begin SDN software development efforts - GREAT JOB SDN team!  The Radiation 
team is in the process of assessing the results of the ATMEL 1355 part 
radiation testing in order to provide a use assessment to the SDO 
project.  Members of the Power System Team and Mechanical System Team 
completed a detailed solar array cell packing factor analysis, which 
results in a revised estimate of 86% panel coverage with solar cells 
(versus 83% assumption baseline).  The calculated SDO solar array power 
output capability will improve by almost 10% as a result of the analysis 
(from 135 solar array strings to 148 solar array strings) - this alleviates 
any potential solar array power output issues.  Finally, the systems team 
met with the SDO AETD champion as a follow up to last week's AETD SDO/GPM 
architecture meeting in order to address issues raised during that 
time.  The C&DH team held a number of board level pre-fabrication 
breadboard peer reviews this week.

The business team has developed an earned value tracking approach and 
started to review with SDO PIs to obtain agreement.  The HMI team visited 
GSFC this week to review ICD Rev. 2, current actions and program 
items.  Mechanical, thermal, C&DH, GN&C, Operations and other items were 
discussed in detail.  Both teams were well prepared and significant 
progress was made in readying the ICDs for baselining and configuration 
control in preparation for PDR.  HMI has planned a series of instrument 
subsystem peer reviews over the next two months leading up to their 
Instrument PDR in November. The SDO team will participate in these 
reviews.  Potential common parts buy items were discussed and a weekly 
working group meeting will be initiated next week.  Candidate item lists 
are being generated by both the HMI team and SDO.  A plan was formulated 
for contract continuity with the PIs consisting of extensions to the 
current contract and a new target date of January 15, 2004 for the phase 
B/C/D/E contract start.  In the area of CCDs, e2v is in the midst of the 
thin-gate wafer run of the preferred demonstration CCD devices and things 
are proceeding normally.  e2v will shortly start the production run of the 
backup thick gate demonstration devices.  Initial probing of the first 
wafers is scheduled for end of October and these results should be ready 
for HMI/SHARPP PDRs.  Radiometric characterization of these initial devices 
does not begin until the end of the year.  The probe test is an inline 
process that electrically confirms the quality of masking and is a good 
indicator of basic device operability.  The CCD working group discussions 
have concentrated on the CCD packaging, the RAL camera design progress, and 
the generation and review of development schedules from both teams.  EVE 
efforts during the past week revolved around developing initial draft 
outlines for the upcoming PDR and the continued evolution of hardware and 
software designs.  Fabrication of prototype parts for the CCD Mount and the 
Filter Mechanism has been completed, pre-fit checks are done, and the parts 
are being readied for shipment to a surface coating house.

The Ground System team completed their package/preparations for their 
Systems Requirements Review (SRR) on 9/30/03.  Operational Concept, 
Detailed Mission Requirement (DMR) and Project Management Plan (PMP) 
documents are in final draft form and will also be presented to SRR board 
members with the SRR package.  In addition, the team presented the first 
draft of a commanding concept to the HMI team during their GSFC visit this 
week.  Copies of this commanding concept have been forwarded to both SHARPP 
and EVE science teams as well.  Finally, TSI Corporation is planning a 
product demonstration of their ground system Front End (data) Processor 
(FEP) the week of 22-26 September.  This is the second demonstration of a 
Ka-band, commercially available FEP product.

The CM team spent a good portion of the week working through intranet 
database issues.  Today CM will announce to the SDO team that the system is 
available to access documents.

Thanks,
Ken
