AGI Technology for Space Exploration

• Bob Hall - AGI Product Manager
• National Space Symposium 2007

2
Vision for Space Exploration

• Missions present several challenges
• Multiple launches
• Rendezvous
• Docking
• LEO departure
• On to the moon
• Entire mission life cycle benefits from AGI
  technology
• Mission design planning
• Mission operations
• Post-mission analysis

3
Mission Design Planning

• Mission design starts with trajectory design
• Launch
• Low Earth orbit
• Rendezvous (e.g., CEV with stage or ISS)
• Proximity operations / docking
• Lunar/interplanetary transfer
• B-plane targeting
• Capture maneuver (e.g., LOI)
• Descent landing
• Formation flying or libration point

4
Mission Design Planning

• Precision trajectory design and maneuver modeling
  with STK
• Numerical integration w/full force models
• Mission sequencing
• Includes sequential, automated, forwards or
  backwards, event-driven
• Maneuver targeting
• Differential corrector adjust controls to
  achieve constraints
• Includes custom engine/thrust models
• Low or high thrust
• Mission fuel requirements trade studies
• Customizable
• Engine models
• Thruster sets
• Force models
• Propagators
• Closed-loop control modeling

5
Mission Design Planning

• Additional design work integrated with trajectory
• Spacecraft attitude modeling
• Payload, Sensor/access
• Coverage
• Custom geometry analysis
• Communications link analysis
• Radar - for approach rendezvous
• Constraints
• Terrain, lighting conditions, communications, etc
• Power
• Solar array sizing / orientation / obscuration
• Conjunction assessment
• OD
• Tracking system design and schedule validation
• Covariance analysis
• Trade studies

6
Mission Operations

• Mission progress monitored live
• Real-time situational awareness
• Same tools used for design now available for
  re-plan or anomaly analysis

7
Post-Mission Analysis

• Evaluate mission as-flown
• Reconstruct actual ephemeris, pointing, payload
  ops, data collection, engine performance, etc

8
Summary

• Tools for complete life-cycle
• Proposals, system design, pre-launch analysis,
  ops, payload support, contingency ops,
  post-mission analysis
• One tool integrates
• Trajectory design
• Sensor analysis
• Communications analysis
• Coverage analysis
• Integrated 2D 3D visualization
• Customizable geometrical analysis
• Constraint analysis

9
Summary

• One tool for LEO, trans-lunar, lunar,
• interplanetary, Martianand beyond
