OpenCPN is free software distributed under the GPLv2 license. A program has been created for the organization of maritime navigation of ships of various types and sizes. The program was created by a group of seafarers who immediately tested it in real conditions, improving and eliminating the shortcomings found. In addition to navigation, it is possible to pre-plan routes.
The program makes it possible to track the current position of the vessel, its speed and direction of movement, taking into account the data of navigation charts and forecasts of tides and currents. An interesting feature is the reception of information from other vessels about their location and course on the radio line. The GPS global positioning system is used for the navigation itself, and in case of its absence the program is used as a planning tool. Cards for OpenCPN are free and available for download on the official website.
While the vessel is in motion, you can select a new map and display it with the required resolution and detail. To use an external autopilot, you must enter the route and waypoints. The documentation included in the program includes a lot of useful information.
