Re: InfraRed = gps ?
Absolutely....If you have a little steroscopic tracker like they had, you can calculate a vector to the emitter and a distance. This right here is enough to be able to tell your postition, but the farther away you are, the less accurate your distance mesaurements are. If you add a third detecor on top of one of the other two and have it slaved to the other emitter, then you can get pretty accurate location data. If you use some trig, you can derive a set of coordinates, and a location on the field.
