SSA Environmental Effects Fusion System
(SEEFS)
• SEEFS merges environmental data with space system parameters to
specify effects on ground & space assets
42
AFRL’s Opinion
SupraThermal Electron, Ion, Neutral Experiment
STEIN (AFRL-0903)
PI (or PM): Chin S. Lin, AFRL/RVBXI
Technical Problem: Current
charged particle detectors are
too large and heavy for nanosatellites
•Leverages new miniature
solid state detector
•Built and tested sensors,
prototype, & components
Military Relevance:
Hardware Status:
• Allow warfighters to distinguish
environmental effects from hostile
threats
– Accurate anomaly root cause analysis
•

• Program Extension - moving launch dates out,
contractual processes
• F19 Sensor deliveries and integration
• Resolution of oscillation reach back
• F19 OLS + SSMIS Fixes
• SSAEM program startup
• DWSS and organizational transition
• Tiger teams at work
• ADM in coordination
• DWSS and SSAEM space allocation
• Wing/Group/Squadron Transition

•
It’s ‘Not Just the Weather’
It’s a lot tougher than it looks
Architecture in its infancy
DoD understands importance…….
BUT the priority is relatively low
Sensors are good……..
BUT the infrastructure must be sound
Many possible paths for the future
Is there money in it???
