Elevation vs time for several satellites, 24 hours

Polar plot of the same satellites.

(see if I get this right)
The satellites go around twice per day.  Relative to the peak of the first 
orbit, the Earth (and receiver) has rotated 180 degrees so the second peak is 
over the pole.

Elevation vs time for a single satellite
That shows how far the satellite orbit drifts over 4 days.

Polar plot of all 31 active satellites, 24 hours
SVN 04 wasn't active.

These are my opinions.  I hate spam.
