Ask HN: Tracking position without satellites

1 points by jlebrech 14y ago ↗ HN

Does anyone know of a commercial system from tracking someones position without the use of GPS.

Would it be possible to install beacons around a sport centre for example to track to location of the sportsmen more accurately than a gps ever would?

There does not seem to be a readily available product on the market although it exists for the military and it would be very useful for sports.

I have no personal experience, but the wikipedia pages on Local Positioning Systems[1] and Indoor Positioning Systems[2] list some commercial offerings.
