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, go to
