Overview• Ground System Schedule• Personnel Plan• Ground Systems Costs• IT Security• Risk Management• Document Status• PDR Peer Review RFA Status


Ground Systems Schedule

Ground Systems Schedule• THEMIS MOC and SOC Configuration During Phase C / D• Development of Detailed Operations Plans and Procedures• Flight Dynamics Software Configuration and Verification with

GNCD Support• FOT Training in Classroom and During Mission I&T• End-to-end Data Flow Testing with BGS, NASA/GN and TDRSS• Launch and Mission Simulations• Dress Rehearsals• Peak Activities In Phase D, Taper Down During Phase E


Ground Systems Schedule


Operations Org Chart

All Aspects of THEMIS Operations Are Performed at UCB / SSLGSFC / GNCD Provides Support in Form of Consulting and Certification

Additional Consulting Support by AI Solutions


O&GS Team Members

THEMIS Operations & Ground Systems Team– Mission Operations Manager (M. Bester)

MOC Staffing

MOC Staffing During Launch & Early Orbit Operations• UCB Flight Operations Team• 24 Hour Staffing with Prime and Secondary Shifts• Critical Commanding During Prime Shift Only• Swales and UCB Engineering Team on Console During Prime

Shift• Instrument Scientists on Console During Instrument

Commissioning• Additional Support Teams Monitor Probe Status Remotely

MOC Staffing During Normal Operations• THEMIS Follows FAST / RHESSI / CHIPS Model• Normal Operations Eventually Run with 8 x 5 Staffing• Transition to Autonomous Operations After First Tail Season• Orbit and Attitude Maneuvers Always Treated as Special

Operations


Ground Systems Costs

Ground Systems Costs• Cost Effective Approach Based on Successful FAST / RHESSI /

CHIPS Model• Mission Operations, Science Operations, Flight Dynamics and

Ground Station Operations Integrated Into One Coherent Facility• Phase-in THEMIS Operations Team Gradually• Hire New Personnel to Enlarge Existing Operations Team• Ground Systems Costs Remain Within CSR Budget• Ground System Development Fully Funded• Required Trade Study Performed in Phase B


Ground Systems Support

Supporting Analyses• RF Link Analysis• Data Volume Analysis• Ground Station and TDRSS Coverage Analysis• Maneuver Analysis• Tracking Accuracy Analysis

Interface Control Documents• Probe to Ground Stations• Ground Stations to MOC• MOC to SOC, FDC to MOC, FDC to SOC• MOC to GSFC/FDF

Support Agreements with Various Organizations• NASA/GSFC GNCD (Code 570)• NASA/GSFC MSP (Code 451)• Ground Stations (WGS, MILA, AGO, HBK) and Space Network


NASA GSFC/GNCD Support• FDAB Support Via SOW for FY05

– MSASS Upgrade Including Nutation Estimation Utility and Small Level of Usage Support (R. Harman)

– Attitude Error Analysis Support for Swales Aerospace (R. Harman)– Validation of FreeFlyer (R. DeFazio, K. Richon)

– Generate Benchmark Runs with GMAN– Compare FreeFlyer Runs Against GMAN– Assess Ability of FreeFlyer to Meet THEMIS Mission Requirements– UCB Will Contract AI Solutions to Generate FreeFlyer Benchmark Runs

– GTDS Software Upgrade and Small Level of Usage Support (M. Beckman)

• FDF Support Via PSLA– Assignment of BGS Transmit and Receiver Tracker IDs– Verification and Certification of BGS Two-way Doppler Tracking– Pre-launch Data Flow and Simulations Support for OD– Orbit Determination Support Following Launch

GSFC/GNCD Support


AI Solutions Support

AI Solutions Support• FreeFlyer Software

– UCB Already Has “Engineer” Version– Upgrade to FreeFlyer Mission Once THEMIS Compatibility Verified
