Pretty sure you can't avoid drift due to fundamental inaccuracies in our ability to take measurements. Even GPS satellites synchronize with ground stations to correct their own drift, making the ground stations the frame of reference. And then the ground stations are all drifting relative to each other because of continental drift.

So in the event that your synchronization signals are being jammed, dead reckoning (where you are your own frame of reference) seems like the best you can do.
