EGSE & Online SoftwareEGSE & Online Software

• Real-time system– Embedded processors running the VxWorks RTOS

– Data acquisition and control by Trigger & Dataflow system

– Monitoring and control of Housekeeping items

– Data acquisition from test-stand COTS I/O modules

• Command and monitoring software (test executive)– Using Interface & Control System, Inc.’s (ICS) Spacecraft Control

Language (SCL)

• Data acquisition, quality verification, archive and distribution• Data visualization and analysis

– SCL provides some help with these last two items

– Third party COTS and Open Source software packages have been, or can be interfaced with SCL to provide the complete solution

SCLSCL

• Precedence– FUSE mission with similar complexity now in orbit for 2+ years

– ICS supplied flight payload software, I&T systems and simulators

• Heritage– 13 year history of mission critical software

• Mature– SCL is a proven, stable, open source product

• Agile– Allows rapid prototyping, deployment, and updates

• Intelligent– Automated analysis and decision-making capability

• Simplicity– Toolkit provides a centralized approach to encapsulating design and

logic
