In June 1989 CAPSY has been introduced for the first time at the ISARC89 in San Francisco. CAPSY (Computer Aided Positioning SYstem) is intended to be low-cost real-time location toll for construction. Operating in working area with dimensions like 300 by 500 feet it is capable of locating itself to an accuracy of +/- 1/8 of an inch in x- and y-direction. Since this introduction CAPSY positioning system has grown from lab-prototype to a commercially available product now. The initial specifications are met (low cost, accurate, portable) and in some cases even exceeded. Although CAPSY positioning system can be used as just a sophisticated measuring and locating tool there might be an even more important role to fulfill in the future. Because of the on board computer capabilities CAPSY can be link between the design stage of the building process (CAD- systems, highly computerised) and the actual building process at the job site (no computerisation at all). Transferring data from the design to CAPSY makes it possible to use CAPSY as one-man survey instrument. At the same time it can function as a real world digitizer on the job site to feed back the as build situation.
