Even with the stationary requirement, this is pretty neat.

One could imagine cheap turn-key devices that self locate and provide an accurate beacon for real time triangulation.

Cheap positioning for construction projects.

Ok, so does this really mean the smartwatch should not move for four hours?

stavros

Yes.

How can this support the panopticon of public safety?

Just one more piece of the behavior recognition and total sensor fusion puzzle. This can also be used to train passive RF based sensing techniques to be more accurate.
