The EZNav position sensor offered by Intelligent Solutions Inc. should 
work in your application.  EZNav is a precision optical position sensor 
that can be used on automated guided vehicles, robots, etc.  EZNav uses 
an eye safe scanning laser with a 360 degree field of view to measure the 
azimuth angle to wall mounted reference reflectors.  This angle data can 
be used to triangulate the position and heading relative to known target 
locations.  

Usually the sensor is mounted on the moving vehicle and the on board 
computer uses the info to figure out position and issue motor commands.
An interesting alternative is to use two EZNav sensors in fixed locations 
and track the moving target.  

More information is available in the comp.robotics FAQ (part 3) or email 
your postal address and I'll send out an information package.
