The TWS group has been pioneering the sector of marine navigation and electronic charting since 1985. In facts, C-Map was part of  the TWS Group of companies till 2007, when it was acquired by Jeppesen, a subsidiary of Boeing.

In 1985 TWS produces Geonav, the very first marine charting system for the non-professional market designed by Mr. Bianchetti and Mr. Petrocchi.
