ACT Simulations Splinter Session Outline
2
Simulations Framework Provide end-to-end test of
simulated instruments scientific performance

• Goals
• Provide quantitative comparisons between
  instrument concepts
• Solidify science requirements early in the
  mission development

3
Simulations Framework Significance

• Early identification of instrument design reduces
  mission technical risk
• Early identification and verification of
  scientific objectives enhances mission
  credibility
• Enhanced communication between development teams
  increases the likelihood of productive
  collaborations
