Here are some links to satellite resources that were referenced during Andy's presentation.

JTrack 3d is a NASA web based java applet that creates a realtime representation that allows you to track, identify, and change your point of view to see satellites that are currently in orbit. Click on the dots and it identifies the satellite. Click and drag on the earth to change the point of view.
