IF you just so happen to have a more clever setup, this indeed becomes possible. Basically, a GPS receiver happens to not compute his own location but the one of his antenna. So if you happen to have a receiver with enough correlators and stuff to properly connect two (or more) antennas and calculate positions for both, it could actually deduce true north. Bearings get better the more space you have between the antennas and the more averaging you can apply. Time for averaging doesn't seem much of an issue in a truly stationary setup, so just try to maximize separation of your antennas.
