Gyroscopic utility mapping is a technique used within the utility pipeline construction and survey sectors to provide 3D geographical information of underground utility pipes and ducts.
As an autonomous Orientation Measurement Unit (OMU) is passed through a pipe or duct, a range of inertial sensors capture its change in heading, inclination, and acceleration at high frequency.
The resulting 3D profile is linked to the start- and endpoint coordinates of the pipe segment and an as-built map is created which can be immediately uploaded into any GIS-platform.
