Sailtracker is an application that collects NMEA data in real time from network electronics navigating of a boat through 3G/WiFi or Bluetooth, allowing you to record and export the information obtained during the session, the route and the polar.

You can use it in combination or alone with he internal GPS of your Android device to get position, speed and heading instead of using the data from the ship, as proof mechanism, or if you do not have an NMEA data connection onboard .

Sailtracker also allows display NMEA AIS information received by the AIS transceiver of your boat.

Sailtracker shows the position coordinates, Speed over ground (SOG), Course over ground (COG), GPS Time, True Heading, Magnetic Heading, Apparent and True Wind Speed and Angle, Depth, Temperature, active Waypoint, VMG, ETA ...

Record waypoints and calculate target distance, VMG, and estimated time of arrival at the destination or regatta mark.

Sailtracker compute polar based on angle and true wind speed, calculated from apparent wind and boat speed obtained by GPS (COG).

Sailtracker includes NMEA depth alarm and anchor, and a countdown timer to output regattas.
