If any of you people other than Ed have a computer capable
of running DOS and you have a GPS with a NEMA 0183 RS232 interface
on it you will love this cool program I wrote ten years ago.
It displays the positions of all 24 GPS satellites as they
come up over the horizon and travel across the sky and sink
down on the other side of the world.

There is also a playback mode that works if you don't have
a GPS. It displays what the SATs look like in So Cal.
