The systems team continued the process of reviewing and providing comments 
on Level 2 Requirements as part of wrapping up the SDO preliminary design 
process and preparing for the upcoming PDR.   As part of this process, the 
SDO Systems Engineering Management Plan was updated with SDO Project, Peer 
review team, Code 590 comments, and submitted to be baselined under the CM 
process.  Members of the systems team also traveled to the HMI/AIA ICD 
working meeting in CA to work a number of technical issues with the 
instrument teams, including updating the SDO pointing, jitter, and 
alignment budget allocations.  The systems and subsystem teams participated 
in a number of technical and developmental meetings this week to address 
SDO development issues, including SDN analog design trade study review and 
design decision making meetings, cPCI connector issues (joint meeting with 
the STEREO development team), parts database and purchasing updates for 
upcoming breadboard units, and ground system development.  Finally, the 
systems team held the Systems Engineering Risk Validation Board (SERVB) 
meeting in preparation for the upcoming SDO Risk Management Review Board 
Meeting , and participated in the SDO project Monthly meetings with the SDO 
subsystem PDLs.

The spacecraft team continued to progress this week towards Mission 
PDR.   A CCB is set for next week to put under configuration control the 
Ka-Band Subsystem & S-Band Subsystem Specifications.  The SDO Project 
monthly was held with all spacecraft subsystems and ground system 
leads.  Near term schedule and FY04 budget status was reviewed.  The 
Mechanical team moved the position of the AIA electronics box from lower -Z 
radiator panel to the upper -Z radiator panel for interference reasons.  A 
determination was made to cancel the Single Board Computer Mid Range RFO 
and re solicit this requirement as a new Mission Suitability RFP.  A 
Request for Information (RFI) has been issued which will allow possible SBC 
vendors to review/comment on the SBC Spec./SOW.  Spacecraft subsystem 
engineers supported HMI/AIA accommodation interface meetings at 
LMSAL.  Topics covered included mechanical accommodation, thermal 
accommodation, C&DH accommodation, spacecraft simulator, jitter and 
integration & test.  Procurement meetings were held on upcoming ACS and 
Propulsion subsystem components.

For the Instruments, e2v submitted their cost and technical proposal to 
Lockheed Martin for the CCD flight development phase.  The proposal is 
reasonable and contains no surprises.  The RAL proposal for the flight 
camera electronics will be submitted later this month.  The checkout and 
operational commissioning of the reformatted CCD test camera continued at 
e2v.  The checkout concentrated on verifying control signal quality of all 
the control signals required to operate and read out the 4k x 4k 
CCDs.  Full CCD testing of first batch samples is scheduled for late this 
month.  The HMI team participated in a productive joint interface working 
group in conjunction with the AIA team and the SDO project.  Significant 
progress was made in evolving the HMI Interface Control Document (ICD), and 
identifying commonalities between the AIA and HMI instruments for the 
initial draft of the AIA ICD.  The meeting brought resolution to numerous 
topics spanning the areas of flight software, thermal, mechanical, 
integration and test, the spacecraft simulator, jitter requirements, 1553 
I/F, and the post-delivery I&T flow at GSFC.  In addition, SAO presented 
details of the AIA telescope mechanical design, including preliminary 
alignment procedures and error budget, and the latest mounting 
configuration.  For AIA, LMSAL ordered 2 filter wheels for life test units 
and SAO started the procurement process for the flight mirror blanks and 
coatings.  EVE is working issues and comments coming out of the PDR in 
December.  The code 300 review team is completing their RFAs and 
comments.  Phase B/C/D/E contract effort continues with discussions on CDRL 
and EVE Specifications.  The target contact award date is January 
31st.  The EVE data rate change CCR cost impact is being estimated by the 
SDO systems group and more information is being sought on costs from the 
EVE team.  Upcoming meetings with the EVE team at LASP include a Risk 
Management discussion on January 29th and a final ICD review on February 4-5th.

The Ground System completed trades associated with the Mission Operations 
Center (MOC) which included the Trending System, Mission Planning function, 
& Alert Notification System.  The team is also busy working on level-4 
system requirements, test plans for these requirements, and preliminary 
designs for software and hardware components.  Peer reviews have been 
scheduled for: Network and Communications (1/28), Operations (2/5), MOC 
(2/11), Data Distribution Center (2/11), Ground Tracking Station (Antenna) 
(2/17).  In addition, the Detailed Mission Requirements document has been 
submitted for CCB review.

In the area of Mission Assurance, the System Safety Program Plan, 
Reliability Plan, and Risk Management Plan have been resubmitted for review.

The CM team continues inputting the MRD into DOORS and has started 
inputting the Structural Analysis and Test Requirements document.  In 
addition, the team has updated the action item database with almost all the 
peer reviews.  The team is also hard at work preparing for upcoming CCB 
meetings.
