Outline

• Purpose

• Architecture

• Build Strategy

• Organization and Responsibilities

• Data Processing


GDS Function

• Control and Monitoring of Instruments during– Telescope Development– Integration & Test– Operations


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.


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


Operations Software Overview

• Instrument Test and Operations Software (ITOS)– 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


Architecture - Build Strategy• Telescope Level (Jan. ‘03) (?)

– ITOS control with flight (development?) mechanisms

• SECCHI Level I&T (Nov. ‘03) – ITOS Tlm & Ctl, interface through SEB and MOC

Emulator

• STEREO Level I&T (Sep. ‘04)

• Mission Operations (Aug. ‘05)


SECCHI GDS Organization


GDS Interfacing Groups• Camera Electronics (UBHAM/RAL)

• Mechanisms EGSE (LMSAL)

• Telescope teams/lab setups (COR1, COR2, EUVI, HI, GT)

• SECCHI Electronics Box (Naval Center for Space Technology=NRL Code 8000)

• Flight Software (NRL)

• STEREO MOC (APL)


GDS Documentation Schedule

SECCHI Data Processing

Stereo Data Flow Overview


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
