C.5 Space Weather Impacts on Systems<br />
Tutorials on space weather <strong>and</strong> impacts are available from 55 Space Weather Squadron<br />
(SIPRNET http://204.20.247.68/index_tutor.htm).<br />
C.5.1 Space-Based Systems.<br />
• Satellite Operation. As satellites are used more <strong>and</strong> more to support warfighters, space<br />
weather effects on satellites become more important. Geomagnetic storms <strong>and</strong> highenergy<br />
particles from solar flares can cause satellites to behave abnormally <strong>and</strong> become<br />
useless for extended periods. In the most extreme cases, these events can cause<br />
permanent failure of a satellite.<br />
• SATCOM. Many theater warfighters are becoming increasingly reliant upon satellite<br />
communications (SATCOM), which is susceptible to scintillation. Scintillation<br />
produces a rapid fluctuation in signal strength similar to the shimmering effect<br />
sometimes visible over a road on a hot summer day. This “shimmering” causes a<br />
SATCOM signal to fade or be lost completely for short periods of time, hindering or<br />
preventing communications. Scintillation is most severe at high latitudes <strong>and</strong> within<br />
about 25 degrees of the equator. In addition to scintillation, radio bursts from solar<br />
flares produce interference (usually for less than an hour) for ground receivers that are<br />
pointed towards the sun.<br />
