How do drones in drone shows manage to calibrate their positions so precisely?

Question

Surely they can’t be using GPS for positions just a few feet apart.

Also, how quickly can they respond to wind and such?

Answer 1

GPS positioning systems are actually pretty darn accurate. My drone can take off, fly around, and return to almost precisely where it took off from all on its own.

Those systems can also be supplemented with other things such as accelerometers and visual systems relying on cameras.
