One possible problem you may be experiencing if the noise is *too* bad is
the quadrant in which your tracker sits in accordance with your emitter.
Having played around with these tracking systems in the past, we noticed
problems when passing between quadrants. -A quadrant being a 3D cubical field
where the emitter is the origin, and each quadrant exists such that positive
X,Y,Z would be one quadrant; -X,Y,Z would be another, etc. Ensuring that your
tracker stays within a quadrant will help.
Something else you might check is if there is any metal near your tracker/
emitter setup. Something as simple as girders in the floor can sometimes
throw your tracker. -Of course, other magnetic fields nearby can mess up
your tracking too. (i.e., many computers). Although the latter shouldn't
mess you up too bad unless you have some gargantuan setup.
As far as experiencing a drop as you get further from your emitter; yes, that
will happen.
If none of that helps, and you need more precision in your readings I would
recommend Ascension's Extended Range Tracker.
Hope that helps!

Sorry if this is a bit off subject - but has anyone
out there played with an Ascension Flock-of-Birds?
I'm seeing *really* poor angular noise levels - when the detector
and emitter are around two feet apart I see around 5 degrees of noise!
Is this typical of the device - or is there something I'm not setting
up properly?
When the emitter and detector are a couple of inches apart, the
noise drops down to almost zero - so I'm fairly sure I'm reading
it correctly.
