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

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

All these responses focusing on just GPS are missing one obvious way to do this: if the drones know how far they are away from other drones to a reliable degree, then you can you can use the rough GPS position of the entire formation.

You can do that with some combination of radar, laser, or ultrasonic range finding.
