Two Companies to Collaborate on Automatic Calibration Options for Constellation 3Di

DULLES, Va.--(BUSINESS WIRE)--Aug. 7, 2002--Arc Second, Inc., the leading provider of 3D-Intelligence products, and Automated Precision Inc, the inventor of the laser tracker and the 5D/6D interferometer, announced today their intention to jointly develop automated calibration techniques for Constellation 3Di, the world"s first proven indoor GPS system with the accuracy, reliability and utility to support large scale metrology.

According to Arc Second"s president and CEO, Edward Barrientos, "Many of Constellation 3Di"s customers need the ability to trace their measurement systems to primary standards. By combining Constellation 3Di"s automatic measurement capabilities with API"s world class interferometers, we are able to provide users with the ability to self-calibrate their indoor GPS system continuously."

"API has always been at the leading edge of new technology trends and we are excited to be working with Arc Second on making indoor GPS a reality," commented Dr. Kam Lau, President and CEO of Automated Precision, Inc. "Automatic self-calibration will provide Constellation 3Di with in-use accuracy advantages by neutralizing a variety of environmental factors that typically degrade accuracy in the factory environment."

About Constellation 3Di

Constellation 3Di was developed utilizing Arc Second"s proprietary 3D-Intelligence technology and 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 their position coordinates independently.

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.

Constellation 3Di is providing facility owners, metrologists, toolmakers and other users of accurate coordinate data with unparalleled flexibility in collecting critical metrology data. For more information about Constellation 3Di, log on to www.constellation3di.com.
