The Sirius Satellite Radio (www.sirius.com) says:

"our three state-of-the-art satellites that rotate in figure eight,
geo-synchronous orbits around the earth"

I know what a geo synchronous orbit is, but what's the "figure eight"
part all about?

These satellites orbit at the geosynchronous distance, but their orbits are
inclined slightly relative to the equator. Viewed from Earth's surface,
they appear to move in a figure-eight pattern as a result.
