Abstract

The precise trajectories of long gas and oil pipelines surveying is a key part of pipeline integrity management (PIM) system. This paper presents a pipeline auto-mapping system based on inertial technology. The system includes an inertial measurement unit (IMU) as the core component, odometers and a set of cartographic landmarks as the auxiliary signals. A post-processing off-line computer system receives downloaded inertial measurement, odometer, and landmarks data and though the use of Kalman filters to estimate the system state. On simulation experiments, the accuracy of integrated navigation system is approximately 0.1m per Km.
