Continuous High-Precision Position-Detection System Utilizing Fiber-Optic Gyroscope for Microtunneling Machines

摘要

NTT has developed a new position-detection system incorporating a high-precision fiber-optic gyroscope, as a technology for use in detecting the position of trenchless microtunneling machines. This system has eliminated the limitations on applications seen in earlier position-detecting methods resulting from line configuration, and it also makes possible continuous real-time measurements, thus lowering the risks accompanying the management and control of microtunneling machines, while also making it possible to achieve more efficient and automated position detection. In sum, the integration of this continuous, high-precision position-detection technology with microtunneling directional control technology allows the realization of a high-performance microtunneling control system.
