- See ships and other AIS targets displayed graphically over free maps from OpenStreetMap.
- Watch as ships move in real time across the map, with their recent tracks displayed.
- Zoom in or out to whatever level you like.
- Assign colour schemes to distinguish targets by type, speed, closeness of approach or recency of signal detection.
- See detailed live information on any selected target: position, course, speed, size, type, flag, destination, ETA and more.
- Attach a GPS unit to show your own position on the map.
- Designate any target, or your own GPS position, as a 'reference' target and see the distance, bearing and closest point of approach of any other target relative to the reference, updated every few seconds.
- Automatically build up a database of every target you have ever detected. Sort the list by name, length, country or other attribute.
- Skim through the history of your sightings: recall what vessels were present last week, last month or a year ago and see their then positions on the map.
- Quickly look up online details and photos of a selected target on sites such as MarineTraffic or Google.
- Attach one or more photos to any target.
- Upload the real-time NMEA data being received from your AIS unit to online vessel tracking sites like MarineTraffic.
- Archive incoming NMEA data to file for future analysis.
- Choose to read the NMEA data with either our own built-in serial port code or the third-party open-source gpsd.
