Sept. 2008EFW INST+SOC PDR EFW SOC Requirements The EFW SOC allows the EFW SOC and Science teams to: –Process and distribute EFW science data in a timely, accurate, and configuration-controlled fashion. –Efficiently command and control the EFW instrument, both during ground testing and on-orbit operations. Governing documents: –RBSP Mission Requirements Document (DOC-REF). –RBSP-EFW UCB Performance Assurance Matrix (GSE and SOC tabs). –RBSP EFW SOC Requirements Document (DOC-REF). –RBSP EFW SOC Software Development Plan (DOC-REF). Contributing Documents: –RBSP Science Data Management Plan (DOC-REF).

Hosted from UCB. UCB has played a similar role on previous missions: CRRES, Polar, FAST, THEMIS. EFW Instrument I&T occurs at UCB, and SOC development builds on the GSE required to support that effort: GSE→Test SOC→FLT SOC.

Sept. 2008EFW INST+SOC PDR EFW SOC Data Processing Organization SOC is divided into two parts: Command, Telemetry, and Ground Support (CTG). Science Data Center (SDC) CTG consists of a single CSCI, CTG. SDC consists of 9 CSCIs, 1 of which is directly relevant to INT efforts: NRT – Near-real Time data processing and display. METUTC -- MET↔UTC Time Conversion PDP – Processed Data Production. DVAL – Data Validation BSEL – Burst Data Selection MDP – MOC Data Products Processing. MAG – MOC and EMFISIS Data Products Processing. ODP – Other RBSP and Geophysical Data Products Processing. SDA – Science Data Analysis. CAL – EFW Calibration Parameter Production.

Sept. 2008EFW INST+SOC PDR EFW SOC Test Plan Detailed GSE-SOC test plan under development (due Q2 or Q3, 2009; supports SDP Phase II). CSCI elements will be tested in isolation to establish basic functionality (test cases; error cases and signaling). –Example: phased introduction of DCB functions and testing using GSE. Elements are brought together into full modules and fed instrument data from known sensor excitations to verify module-level functionality and requirements fulfillment. –Example: basic instrument functional tests during I&T. End-to-end testing at each stage of integration to weed out problems early. –Example: testing of complete PDP chain as early as possible during Phase D using data from SC I&T and environmental tests.
