The weekly systems team meeting included a presentation on the updated 
bi-propellant system concept, including a detailed operations concept of 
the system configuration and operation through the various SDO operational 
phases.  The Systems Team continues to work with the subsystems in 
preparing for the upcoming subsystem PDRs, including refining architecture 
concepts and reviewing subsystem level 3 requirements.  As part of the 
concept development process, the C&DH and GN&C subsystems held peer reviews 
on various breadboard design implementation concepts, presenting emerging 
design details for review by the SDO subsystem and systems team.  Finally, 
the systems team continues to work with the subsystem teams in supporting 
the ongoing LMSAL AIA accommodation effort.  The subsystems have started to 
incorporating designs to accommodate AIA; all subsystem peer reviews 
planned in the next three months will reflect a design that accommodates 
the AIA.  Mechanical Systems have determined that the optical bench design 
does not need to be changed for AIA.  An assessment of the single event 
effects testing of the Atmel 1355 ASIC was completed by the Radiation 
group. Calculations of expected error rates based on the data indicate an 
upset rate of approximately 1 upset per 3 years per chip during solar 
minimum and 1 upset per 25 years per chip during solar maximum.  Based on 
this assessment, the SDO Project is continuing to use the Atmel 1355 ASIC 
in non-critical to SDO survival applications.

For the instruments, we worked the accelerated contract efforts for the 
Lockheed's AIA including generation of SOW and revision of JOFOC 
(Justification for Other than Full and Open Competition).  In addition, we 
completed the technical evaluation of the Phase A extension proposal from 
HMI and continue to work on the final contract documentation for the Phase 
CDE contracts for EVE and HMI.

This week the Ground System team successfully conducted their System 
Requirements Review.  Approximately 32 RFAs were generated and accepted by 
the Project.  Science Operational Working Group (SOWG) meetings are now 
being conducted weekly, a change from monthly.  The MOC Design Engineer met 
with PAO to incorporate their input into the MOC design layout.  The intent 
is to see if there is a design that would benefit VIP tours now that the 
HST MOC has been moved to Baltimore.  The TSI vendor gave their front end 
(data) processor (FEP) demonstration on 10/02.  Finally, the Ground System 
Manager successfully had the White Sands-GSFC MOU signed off by Codes 450, 
460, 400, and Center Management.

In the area of CM, the team: released 8 mechanical pull test drawings; 
worked action items & the CCR module of the database/intranet; & attended a 
Requirements Definition training course in order to better support the 
Project and to assist the Systems Engineering Team with requirements 
management and the writing of requirements.
