Potential Payoff
PROBLEM Loss of SATCOM link
RESPONSE Mitigation of Ionospheric Effects
CAUSE Enemy, Equipment, or Environment?
Jamming or attack
Change Frequency, Data Rate
Equip. failure Radiation effect
Use Alternative Links
Scintillation Effects
Wait for Disturbance to Pass
Knowledge of space environment permits optimal
