The European Geostationary Navigation Overlay Service (EGNOS) is a satellite-based augmentation system (SBAS) developed by the European Space Agency and EUROCONTROL on behalf of the European Commission. Currently, it supplements GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections.

The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.
GNSS augmentation is a method of improving a navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process, for example, the Wide Area Augmentation System, the European Geostationary Navigation Overlay Service, the Multi-functional Satellite ...

This meant barges had to be locked in two phases. This operation was dangerous and time-consuming. It backed up river traffic and increased expenses for the towing industry. The Corps initiated the Ohio River Navigation Modernization Program in the 1950s. The program's purpose was to replace the system of outdated wicket dams and small locks.
They are located at mile point 606.8, and control a 72.9 miles (117.3 km) long navigation pool. The locks and their associated canal were the first major engineering project on the Ohio River, completed in 1830 as the Louisville and Portland Canal, designed to allow shipping traffic to navigate through the Falls of the Ohio.
The Falls of the Ohio National Wildlife Conservation Area is a national, bi-state area on the Ohio River near Louisville, Kentucky, in the United States, administered by the U.S. Army Corps of Engineers in partnership with the Indiana Department of Natural Resources. Federal status was awarded in 1981.
