Hey David,
There's an amateur radio program for just that purpose. Several, in
fact. Here's one:

The one you want is the AMSAT program.
Probably too much for the Arduino, at least the 8 bit ones.
Here's a peecee utility that has most of what you need.
http://www.dxzone.com/catalog/Software/Satellite_tracking/
It started out as a Linux program but the author abandoned it in '94 and
this guy picked it up, improved it and ported it to windoze. He had
started a backport to Linux.
I liked the program enough that I finished the backport and sent the
results back to the maintainer. Until he incorporates those changes
into the main program, you can get the Linux version here:

You'll have to add the Kepler components but the AMSAT program should
have code that you can use for that purpose.
I know that sunwait will compile for the Arduino because I tried the
port with avrgcc 8 bit version. I didn't try to load or run it but the
binary is small enough.
