Avtec Systems, Inc. v. Peiffer
21 F.3d 568 (4th Cir. 1994) - full text opinion
Avtec Systems is still around, and it is actually one of the world's largest providers of satellite tracking, communication and engineering services. The same cannot be said of Kisak-Kisak, Inc., which seems to have disappeared.
If you don't know much about satellites, here is a good introduction. Make sure to learn about the various types of satellite orbits. As for simulations, try this real-time 3-D representation of the orbits of over 500 satellites. Alternatively, you can enter a location on the ground, and receive a list of times and coordinates for various satellites to pass over-head.
