GALEWATT was a development project for the European Space Agency, aiming to replace the conventional River Information System and local DGPS (Differential GPS) stations by collecting direct Egnos signal from the transponders installed on board vessels, making the implementation of the Trans-European RIS easier and cheaper. Demonstration of the availability of improved EGNOS, or Galileo, satellite navigation (generating strategic traffic images, improving RIS in relation to the EGNOS parameters, introducing an anticollision system and related alert mechanisms) was also included. INOV partners in this project were Via Donau, Telematica and Kongsberg Seatex.
