Different Set Ups

  1. "classic" set up - raspberry installed on your boat, one ore more tablets for display and interaction. On the tablets there is only a browser required - so you can use android, windows, IOS. You could additionally use other devices like laptops or smart phones for display.
    The raspberry will set up a WLAN where the devices can attach.
    You can attach multiple devices - you can have different displays on each of them - like the chart on one device and a dashboard on another one.
    The charts have to be available in a raster format (gemf) - a converter is available.
    I mainly used:

    • one tablet down below at the chart table
    • one tablet below the dodger

      AvNav klassisches Setup
      minimal "classic" set up- raspi, gps mouse, USB-RS232 gateway, power supply and 2 tablets
  2. AvNav as NMEA multiplexer and WLAN gateway
    In this sert up AvNav receives data from NMEA-0183 (and a seriel-USB adapter),bluetooth, NMEA2000 or from IP and provides them at different outputs. You can mix this set up with the "classic" one - the NMEA multiplexer is always available.
    Available data outputs:

    1. NMEA-0183 (via USB-serial adapter)
    2. IP (TCP and UDP) - local or via WLAN
  3. Android "stand alone"
    AvNav is available as a normal app on the android device. You can receive data from the internal GPS but you can also receive them via bluetooth, IP or USB device. The display functions are identical to the normal app.

  4. Android „master slave“
    The app will only be installed on one device (maybe an android car radio - see DIY-Plotter Android-Radio)and can be used on this devices as well as on other devices in the same lokal network (WLAN). On the other devices you only need a broweser - so you are free again to choose your system on them.
    In the picture - an old Ipad3 as second display.

    Android master slave: the lower tablet is working as the master, the upper one as a second display.
  5. Windows (or Linux) Desktop
    There is a ready to go installer for windows, for Linux we have packages available. This way you can install AvNav on your desktop computer (or your laptop). The primary focus for this installation is converting of charts (like BSB charts) but you can use the complete functionality of AvNav. Again you can connect other devices that have a browser installed and use them as a display.
