Still pretty generic. For example, I'm about to push code that tells
u-blox to send ECEF data. Your nav that complex?
Complex enough to want RTK data? New drone autopilots use that.
And, of course, it depends a lot on what GPS you have...
The overlap between what different GPS can ouput is surprising small.
