Inside?
Outside?
Cost?
If the answer is outside and cost is not an issue.
a Real Time Kinematic (RTK) GPS system could do the job.
You should be able to get 1Hz positions to better than 10cm with a
rover and fixed base setup.
Ask the question on sci.geo.satellite-nav

Something like UWB/802.15.3a, but that is already in production.
Basically you have an RF transmitter attached to the device you are
tracking which constantly sends out beacons. These beacons are
received by a number of other devices in known positions which are
able to use the differences in time of arrival to triangulate the
mobile devices coordinates. Tricky, because you need sub-nanosecond
timing to get accuracy < 1m, but this is what UWB allows you to do.

Yes.

Jon, what do you mean by this?

In other words, do you intend to send a new position every .5s, or receive a
report on the position of the device? Assuming the later, do you need
intermediate positions, or do you just need to know once the device has hit
its target?
I think that a good rifle would do the trick, shooting at a target with a
pressure transducer of some sort to report a hit.

Hi,
Does anyone know of an existing technology that allows for
high-resolution wireless positioning, with roughly the following
characteristics:
- Positioning accuracy of 10-50cm
- Position updated every 0.5s or less.
- Range 200m+
Cheers,
JonB
