Space Weather for Situational Awareness

• Ted Driver

2
Introduction

• Quick intro about what we do
• Review of space environment technologies our
  customers use
• New work for situational awareness (SA) users
• Current limitations

AGI Tools navigation perspective

• Components
• Dynamic Geometry Library
• Navigation Library
• Terrain Library
• Web enabled
• .Net C

• STK
• Space segment
• GNSS satellite and receiver design
• Communications analysis
• NavTK
• User segment
• High fidelity receiver modeling
• Navigation error analysis
• ODTK
• Control Segment
• GNSS Measurement processing
• Orbit/Position/Maneuver determination

Current AGI space weather modeling

• STK/Space Environment
• Radiation dosing over time
• AFRL and NASA models used
• South Atlantic Anomaly
• effects
• Micrometeoroid impacts
• Vehicle Temperature
• NavTK and ODTK
• IRI2001 Ionospheric model
• as truth

New work

• Re-engineering Space Environment tool
• Working with a new partner to seamlessly
  integrate pieces from AF-GEOSpace models into STK
• Moving to IRI2007 model
• HF comm outage developments
• Current model depends on propagation loss
  calculated from slant range TEC values not
  easy!
• Near real time ionospheric error analysis tool
• Shows unique capabilities of our components with
  readily available data

Iono error analyst
8
Current limitations

• Only viable at ground level

43 miles
9
Current limitations

• Only valid over CONUS
• World wide slant range TEC would be extremely
  beneficial

10
Current limitations

• Data only available in near real time
• 30-45 minute lag
• Predictive capability would make situational
  awareness more complete

Summary

• AGI tools help our customers understand their
  environment
• Current space weather tools address customer
  requested capabilities
• New work will address wider range of data and
  data availability
• New technologies will deliver precise, accurate
  information in new ways
