Yes, it must have a recalibration mechanism when fresh "reliable" data becomes available. The key here is the nature, cost and wider availability of the sensors used.

This sounds like a very appropriate solution since GPS and WiFi are often only intermittently available indoors. Mapping programs are just starting to gather information about the insides of structures to make sense of tghe computed routes. It would be interesting to see the accumulated errors before a waypoint resolve after encountering the next one. I'm guessing the dead reckoning mapped route rescales to align with the known waypoints.
