There is only one Spy Sat mod available that is compatible with GWX Gold.
That is Jimbuna's version. I have a couple of links available but I know there was a file revision after initial release, so it maybe be best if Jim points you in the direction of the correct one.
Having not used this mod for awhile now, I can't recall exactly the details, however the mod extensively overwrites the campaign files and in the case of older Spy Mods scripts vessels that are no longer in GWX (or re-designated).
