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

3. AGI technologies

4. AGI Tools – navigation perspective

AFRL and NASA models used
South Atlantic Anomaly
effects
Micrometeoroid impacts
Vehicle Temperature
NavTK and ODTK
IRI2001 Ionospheric model
as ‘truth’

6. New work Re-engineering Space Environment tool Moving to IRI2007 model
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

7. 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

11. 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
