Optimum control of machine position for curved pipe Jacking: The north seeking gyrocompass is an absolute directional sensor that detects direction from the North Pole. This sensor has been used with extremely satisfactory results in curved pipe jacking systems. Real time machine coordination and position can be determined by absolute direction and distance data. This systems allows drastic reduction in survey work. The position of the machine can be derived from calculation of excavation distance and calculation of attitude angle(azimuth and pitch). Suppose you excavate a short distance, △L from a known point, I1, in direction θ1, I2 can be obtained by calculation. Similary, I3, I4, ......In can be obtained.

• Absolute direction:Gyrocompass detects absolute direction. Servo type acceleration meter measures pitch and roll.
