First, which version of Gpredict are you using?  Second, what's your OS?

If you're using Linux, look for a hidden directory in your account
with the format:


This may vary between distributions and may have a different name, but
directory won't appear on your desktop.  You'll find it using:

ls -al /home/xxxxx/Desktop

where xxxxx is your account name.

That directory will have some subdirectories.  The ones you'd be
interested in are satdata (which contains the TLE files) and tsrp
(which have the frequency data).

The TLE files are of the form NORAD-ID.sat and the frequency files are
NORAD-ID.tsrp.  Those are text files which can be edited and copied,
but they need to have the correct NORAD ID number as their name.

Once you've copied them, you'll have to log out and log in again in
order for Gpredict to find them.  After that, you can configure
Gpredict to display the new satellites.

Just a word of caution:  you may have to do this a few times before it
works, or at least I had to do it on my machine.  I suggest you copy
some existing files onto your desktop, edit them for the new birds,
and then copy them into the correct directories.
