This is not a bug. GPS track is based on the motion of the plane, not where the plane is pointed. Like a real GPS, it doesn’t take into account any plane heading, it just looks at the GPS and determines which direction the plane is going based on sampling the location. When the plane is basically s…

No, this is a bug. Try it in the sim. milliseconds/millimeters movement of the plane is causing the GPS GROUND TRACK simvar to flip 180 degrees. That is obviously not what any useful track simvar would do, and it’s nothing to do with any gauge. The MSFS GPS ground track simvar calculation was writt…

The track has always been the instantaneous vector derived from GPS position sampling and that code has not changed in the sim, and remains the same as in FSX and earlier. We’ve been working around that in instrument code since the release of the sim (again, as real instruments so), and it is not r…

I’d venture that you’re both correct to an extent. It’s true that GPS ground track is the direction of the vector connecting successive GPS positions and noisy positions will yeild even noisier headings, but real GPSs also don’t compute fixes at millisecond intervals. A 10 Hz GPS computes a fix ev…
