First Look: Utilizing Inertial Navigation Technology for 3D Mapping, Locating, Management

Over the last two decades, significant advances have been made in the quality and application of inertial navigation technology targeted at mapping underground pipe and duct assets. This article provides information on pipeline technologies that are available to map a minimum internal diameter (ID) of 1.6-inch to larger sizes. The pipeline mapping system offers a range of solutions that can map any pipe, regardless of its material, depth or type of utility.
