Driven by automation technology, some advanced dredging equipment is also equipped with navigation and positioning systems and remote monitoring systems, realizing semi-automatic or fully automated control of the operation process. These technologies have been widely used in dredging projects in large reservoirs, lakes and other waters, effectively improving dredging efficiency and construction quality.
