## Reviews Relevant to GSSC

- Ground System Requirements Review (7/03)—Provided the driving requirements for the ground system and the operational design within which these requirements were derived.
- GSSC Peer Review (11/03)—Demonstrated that GSSC design is at PDR level.
**GSSC Detailed Design Peer Review (7/04)—Demonstrate that GSSC design is at CDR level.**
**Ground System Design Review (8/18-19/04)—Demonstrate that the requirements, interfaces and design are of sufficient maturity to begin ground system development.**
- Mission Operations Review (10/05)—Schedule and approach for achieving operational readiness.
- Operational Readiness Review (12/06)—Launch readiness of the Ground System.

## Major Items from Corcoran Notes, GSSC DDPR

- Tako needs augmentation to handle optimization of multiple targets in pointed (or dithered) observations — MOU deliverables and schedule agreed to with Omitron, Project.
- BAP downtime to be commensurate with GCN downtime (currently ~ 0.5%, level of “human error”) — Bldg 2 plans being discussed to improve on emergency power for GCN, BAP.
- GSSC resources need to be devoted to installing, maintaining, validating the LAT backup pipeline; data volume to be handled is not yet well defined — Discussions ongoing with LAT team;  Tom Stephens consulting on LAT pipeline implementation.
- Science and Operations Data Products ICDs are not complete — {MOC, LAT team, GBM team, GSSC} working on ICDs.
- Current sequence of timeline construction allows possibilities for “conflicts” — Ops splinter group formed (Jon Degumbia) ...
