The GPS or the INS (OK, probably not a reality for most of us) is your heading source. Think of it as a master compass.
Remember this is an exercise in recording the compass deviation and making corrections as necessary. Don’t think of it in terms of flying a track from Point A to B, because you’re not. You’re simply flying a constant GPS heading. It’s surprisingly simple.
