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.Includes AIS display if provided by the external (TCP) device.Easy waypoint and route creation and modification. Store tracks in gpx format on your SD card.This app is an android port of the Raspberry Pi solution - see http://www.wellenvogel.net/software/avnav/index.php (German).Charts must be converted into the GEMF format before they can be used (for necessary software follow the above link).The app runs without any issues starting from KitKat (4.4). For older Versions (min 4.0) you either need to install the Chrome browser and operate in browser mode or install the runtime of https://crosswalk-project.org/ (see my app store) - an embedded Chromium browser. If your device is below KiKat the App will ask you to install this runtime app (AvNavXwalk). This inconvenience is caused by a lot of issues in older android browsers.
