Phones have had accelerometer/gyros for a while now. Problem with pinpointing one's location is how to get a starting fix and how to deal with drift and loss of signal.

The way devices have dealt with it is to periodically confirm and baseline with a satellite fix.

If this method does away with all that, it could remove the reliance on overhead signals and those trying to jam them in hostile zones.

Pretty cool. Lots of potential.
