AvNav Navigation

Navigate your sail boat using Electronic Raster Charts on your SD cart.

Use the internal GPS device or connect to a GPS via TCP, bluetooth or serial device via USB-serial adapter.

Features a complete NMEA0183 multiplexer to receive and send NMEA data from and to connected devices.

Includes AIS display if provided by the external device.

Easy waypoint and route creation and modification. Store tracks in gpx format on your SD card. Import and export tracks and routes in standard gpx format.

Master-Slave mode - display on other devices in the same network.

Background mode: Use the multiplexer to provide NMEA data for other apps.

This app is an android port of the Raspberry Pi solution - see http://www.wellenvogel.net/software/avnav/index.php (German).

For an online demo see http://www.wellenvogel.net/software/avnav/viewer/avnav_viewer.html?navurl=avnav_navi.php.

The app runs starting from KitKat (4.4).

If you are looking for a solution to integrate with the Bus systems on your boat refer to my project at https://github.com/wellenvogel/esp32-nmea2000.
