  If you like the Oscar locator take a look here,
http://www.tomdoyle.org/HomePage/HomePage.html
The fourth one down. Download,enter your grid locator, make sure your
computer clock is correct and select satellite and your good to go. Wont
point your antennas or run your rig but it like the Oscar locator your use
to, just the computer version. I use Satpc32 and if you have your location,
PC clock and the Kep's up to date you should be pretty close. Good Luck
