GDS Function
• Control and Monitoring of Instruments during
– Telescope Development
– Integration & Test
– Operations
SECCHI Consortium Meeting, July
2001
Architecture - Components
• Computers (PC or Sun workstation) used to
interface with and/or emulate instruments or
flight electronics
• Software
• Instrument and mechanism drivers and interfaces
• Telemetry and command
• Data processing
• Ancillary lab equipment
– Stimuli, power, detectors, etc.
SECCHI Consortium Meeting, July
2001
Architecture - Components
• Telescopes
– Camera: 1355 (Spacewire) Interface
– Mechanisms: controlled via MEB
• SEB: SECCHI Electronics Box
– Where the Flight S/W lives, interface with S/C

Developed at GSFC
Flight Heritage: TRACE, Triana, Swift, Mars Pathfinder, …
Hosted on a UNIX or PC Workstation
TCP/IP, serial, and IEEE-488 external communication
Accepts CCSDS telemetry transfer frame data
Automated Test Procedures using System Test and Operating
Language (STOL) interpreter
• BP/COMET
– Developed for NRL Blossom Point satellite
– Being used by SEB developers

Architecture - Build Strategy
• Camera Level
– (~Dec. ‘01): IDL controller on Windows PC
• Mark Cooke, UBHAM
– (July ‘02): ITOS flight-like camera control

Camera C driver handles CCSDS packets (UBHAM)
ITOS Image Acquire and Save
ITOS Camera Commander
ITOS GPIB-488 Handler
IDL Image Processing to FITS

SECCHI Data Processing TBDs
• Calibration
– Determine before launch: geometric, vignetting,
flat field, stray light, photometry
– F-corona model/background?
• Stereo analysis resource requirements
– Beowulf? Fast PCs? Supercomputers?
• CME Search & Characterization
• Data Archive & Distribution
