(I'm thinking traditional TDOA techniques may not work with gps
signals.)
There are commercial products available:

These devices claim less than 1 degree RMS heading accuracy.
Here the antennas are integrated and a fixed 0.5 meter apart. They do
(or did) make a board that could be used with separate antennas, but I
can not find it right now.
I think this is the one:

I have no idea of how the math works for computing heading.
