Hey David, There's an amateur radio program for just that purpose. Several, in fact. Here's one: http://www.dxzone.com/catalog/Software/Satellite_tracking/ 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: https://dl.dropboxusercontent.com/u/81715047/sunwait_linux.tar.gz 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.
