Global Positioning System aided autonomous construction plant control and guidance
The advent of Real Time Kinematic (RTK) Global Positioning System (GPS) positioning means that this technology can now be used for dynamic control and guidance applications. The paper outlines the recent advances in GPS technology, which have enabled RTK GPS to become a reality. Tests have been carried out in construction plant control and monitoring applications with a demonstrated precision of the order of a few millimeters. The results are compared with those achieved using a laser level and a digital automatic level.
