The Three Gorges GPS vessel management programme, promoted by the Three Gorges Navigation Administration, has been adopted by an increasing number of shipping lines and their vessels, according to the administration.

Today, more than 95 per cent of all vessels passing the shiplocks use the system to apply for passing slots and obtain real-time navigational information. A total of 3,375 vessels are now regular users of the service. This has contributed to increased efficiency in the management of the shiplocks.
