GNS-P Gyro Navigation System for Pipe Jacking


Spanish E-mail How to print Versión PDF Web Map	Gyro Navigation System for Pipe Jacking GNS-P the guidance system for pipe jacking curves. GNS-P is designed for curved drives of any radius. The system can be used in tunnels with a diameter of at least 800mm. No components are installed in the pipe and line-of-sight is not necessary between the components. The north-seeking gyro compass, Northstar24, is permanently mounted inside the TBM. Upon request, it calculates the direction due north as a reference to the machine axis. The current position of the TBM is calculated via coupled navigation. The HWL system supplies elevation data permanently. For an easy replacement all U.N.S. systems are using the same fixing system. In this picture you can see a north-seeking gyro compass mounted on the same braket as the ELS target.
