STATUS/ACCOMPLISHMENTS
This week we continued our detailed schedule reviews with 6 more subsystems 
- detailing/integrating a 6 month rolling wave schedule with each 
subsystem.  The systems team has been working on prioritizing activities 
that need to be completed in the current preliminary design phase. 
Therefore, this week's systems meeting focused on the generation and 
definition of subsystem requirements (time line, format, & 
management/traceability of subsystem requirements).

This week the HMI and SHARPP teams are visiting the E2V (CCDs) and RAL 
(camera electronics) vendors in order to conduct kickoff meetings.

The Ground System team began drafting a Request for Information (RFI) to 
solicit information on encoders and digital receivers planned for use in 
the Data Distribution Center (DDC).  This information will help determine 
if industry should supply this equipment or if it needs to be a GSFC 
in-house design.  This RFI will complete the third major investigation 
needed to finalize the overall ground system architecture.  The previously 
completed RFIs focused on antenna and MOC/communications/mission ops. 
requirements.

In the area on Configuration Management (CM), the team updated the document 
tree & action items, formatted two documents for the Single Board Computer 
procurement, attended a DOORS (requirements traceability tool) 
demonstration, & worked issues related to how we will reference System, 
Subsystem, and Configured Items within our CM database and our photo 
database.  In addition, the CM team developed the comments matrix for the 
CCR to release the Mission Assurance Requirements document (SDO-CCR-010) in 
preparation for our first official SDO CCB (5/22).

I welcome Brent Robertson to the SDO team as our Observatory 
Manager.  Brent is in the process of being detailed from AETD and we look 
forward to him working with and leading the subsystems to PDR in the areas 
of schedules, implementation plans, documentation, & procurements.

Thanks,
Ken
