## ICESat Ground System Schedule Drivers

## IGS Documentation Flow

## Supporting Documentation Available to Date

- ICESat Mission Systems Requirements Document (MSRD) -Final.
- ICESat Mission Operations Requirements Document (MORD) -Draft.
- RF ICD -Near Final.
- Data ICD - Very rough Draft!
- Various Ball Spacecraft documents (T&C Hnbk, Spacecraft Requirements document, etc.).
- GLAS Instrument Requirements Document - Final.
- Various Science Computing Facility Documents - Draft & Final.
- GLAS Instrument Description Document - Draft

## Schedule Development Needs the Following Elements

- Facilities Readiness
- Personnel (when available & training)
- Procurement Items (any items needed)
- Documentation (ICDs, Manuals, Operational Agreements, Support Plans, User’s Guides, MOU/MOA, etc.)
- Hardware & Software Procurements
- Equipment Installation & Check-out
- Software Coding, Installation, and Check-out
- Element Testing
- Ground System Test Readiness
- Simulation & Rehearsal Support
- Reviews & Status Reports
- DEPENDENCIES  (predecessors) for element schedules.

## IGS Master Schedule - Line Item Elements to be Developed

- Major Reviews & Documents
- EPGS & WFF
- Ebnet & NISN
- EDOS
- SCF & ISIPS
- DAAC
- MOC & FOT
- FDS
- ISF & IOT
- IGS Testing, Simulations, Rehearsals
- L&EO Support
- Calibration & Validation Support
- Normal Operations

## IGS Overview (as it stands today - the “Baseline”)

## IGS Major Interfaces I2 Chart

## Organizational & Funding Considerations

## Top-Level IGS Trades in Process

- Trade A:  Flight Dynamics System
- GSFC FD (GSFC develops and provides L&EO support, then turns over to MOC/FOT for routine operations).
- Ball FD - Ball does it all.
- Trade B:  S-band RT, PB, and CMD Data Processing
- EPGS (via PTP/SAFS) processes RT & PB S-band simultaneously
- ** EPGS processes CMDs from MOC.
- ** EPGS processes just RT telemetry and forwards to MOC.
- ** EDOS processes PB only and forwards to MOC.
- Trade C:  X-band Level Zero Data Processing
- ** EDOS does all X-band processing and strips out GPS raw data.
- EPGS does all X-band processing.
- SIPS Extention - all X-band processing.

- **  = Most likely decision.

## Top-Level Trades Overview
