AIS Functionality
When connected to an AIS system via a wireless NMEA link, NavLink will provide a real time overlay of AIS targets and CPA and TCPA alarms. Internet AIS requires Boat Beacon app

HorizonView
Overlay chart & AIS objects on the iPhone or iPad camera image to create an augmented HorizonView display, that makes Nav-Aid & vessel identification simple and reliable

Plan & sail routes
Instant route and waypoint creation by tapping on screen. Route reverse function and route overview with inter-leg bearing and distance. Share your routes via dropbox and email with other users

NavLink Charting
NavLink utilises the latest S57 based NOAA digital mapping & features automatic free updates for 1 year. With vector mapping, you can manage your layers of data to de-clutter the screen or maximise information. NavLink supports all key charting feature such as buoys, lights, bridges, depth contours, spot depths, depth contours, anchorage & military areas, weather buoys

Interfacing
NavLink is compatible with all Digital Yacht's wireless NMEA devices such as the iAIS, WLN10, WLN10HS, NavLink, iNavHub & PilotLink that stream wireless AIS data to your Apple device

If you have a WiFi-only iPad you will need an external Bluetooth GPS receiver to enable navigation. 3rd Party units are available such as the Garmin Glo.

Please note: Continued use of GPS running in the background can dramatically decrease battery life
