摘要

Easy system situation on a nautical or geographical letter: It is a system that allows the user to quickly and easily placed over one nautical chart or geographically. In nautical sports, current use of GPS positioning system gives us the latitude and longitude of the location. Transfer this information to a conventional nautical chart it is complicated and errors in the process, because of its size and the limited space available on board. The invention solves the problem by reducing the cards to a more appropriate size (about 60 cm. X 45 cm.) And assembling these cards on a particular board, which has two strips to be moved transversely and matching them with scales of latitude and longitude, expressed at the edges of the charts, it tells us, at the point where they intersect, the geographical situation in which we find ourselves.
