iNavX™ - Marine Navigation for iPhone and iPod Touch

iNavX™ brings NOAA RNC raster United States waters marine charts to your iPhone or iPod Touch.

With iNavX™ you can use the iPhone's built in location services (i.e. GPS, cell tower, wifi) to plot your position in real-time on the marine chart.

Using the iPhone's or iPod Touch's WiFi connection, iNavX™ can act as a repeater for popular marine navigation software that supports NMEA data over TCP/IP such as MacENC or other MS Windows marine navigation applications (i.e. Coastal Explorer, Expedition, GpsGate). This includes GPS, AIS receivers & transponders, and Instruments (Depth, Speed, Wind, etc.)

In addition to real-time chart plotting, iNavX™ supports waypoints, track log, and measuring bearing/distance.
