Ask HN: Tracking position without satellites
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.
