Differential Impedance Obstacle Detection Sensor (DIOD) - Phase 2

The objective of the Differential Impedance Obstacle Device (DIOD) project is to develop a tool that can be coupled with a pipeline drill rig to detect pipeline obstacles in the drill path. The final deliverable is a device that can be commercialized. GTI will conduct a series of in-ground tests to prove that the DIOD can detect obstacles of at least three different materials (plastic, ceramic and metal) in at least three different soil materials (loam, sandy soil, and third type of soil) and demonstrate that the sensor is robust enough to withstand HDD conditions.
