GPS is great and has helped nearly everyone at one stage or another to find their way.
The problem is that it doesn’t work indoors and all the mapping companies are working hard on finding a solution so you can find your way around the shopping mall or the supermarket.
Now there is a new kid on the block called IndoorAtlas.
Developed by a team at Finland’s University of Oulu, their method relies on identifying the unique geomagnetic field of every location on Earth to get positioning through a mobile device.
It is very accurate, to less than 6.6 feet, and it can work without triangulations of wireless signals and at any location. IndoorAtlas has already conducted tests in a mine 4,593 feet deep.
Geomagnetic location-finding is already available through an Android API, so hopefully there will be plenty of apps coming our way soon.
