Arc Second To Unveil Indoor GPS for Metrology

Arc Second Inc. announced that it is unveiling Constellation3Di at the Coordinate Measurement Systems Committee (CMSC) 2002 Conference which will be held at the Providence-Warwick Hotel in Warwick, RI from July 15 to July 19.

Constellation3Di, which was developed utilizing Arc Second's proprietary 3D-Intelligence technology, is the first proven indoor GPS system with the accuracy, reliability, and utility to support large scale metrology. Using signals from transmitters that emit infrared light, small receivers can calculate xyz coordinates independently. Therefore, like GPS, the number of receivers in a single workspace is unlimited. Uses include the measurement and inspection of large tooling, sub-assemblies and infrastructure in the aerospace, automotive, rail, and shipbuilding industries. Constellation3Di is providing facility owners, metrologists, toolmakers and other users of accurate coordinate data with unparalleled flexibility in collecting critical metrology data.

"The ability to monitor hundreds of points simultaneously and economically, while not compromising accuracy, will become critical if factory wide positioning systems are to become a reality," noted Edward Barrientos, President and CEO of Arc Second. "In the 1990s, GPS based measurement solutions radically changed the optical surveying instrument market. Today, Constellation3Di promises to equally disrupt the portable coordinate measurement market by offering users a powerful new value proposition for their metrology related outlays."

Arc Second will be demonstrating the Constellation3Di system during the entire CMSC 2002 Conference. Additionally, Thomas Hedges, Vice President of Engineering and Technology for Arc Second, is scheduled to present a paper titled "Constellation3Di : Indoor GPS for Metrology" which will introduce the technology, its error sources, and its applicability to indoor metrology problems.
