AGI Technology for Space Exploration: 

AGI Technology for Space Exploration Bob Hall - AGI Product Manager National Space Symposium 2007

Vision for Space Exploration: 

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

Mission Design & Planning: 

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

Mission Design & Planning: 

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

Mission Design & Planning: 

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

Mission Operations: 

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

Post-Mission Analysis: 

Post-Mission Analysis Evaluate mission ‘as-flown’ Reconstruct actual ephemeris, pointing, payload ops, data collection, engine performance, etc

Summary: 

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

Summary: 

Summary One tool for LEO, trans-lunar, lunar, interplanetary, Martian…and beyond
