The Nav-Tracker GPS tracking system from Paradox Marine can be used to track a boat from anywhere in the world with an internet connection. The system allows users to view the boat on Google Earth.
When the transmitter is mounted on a vessel and armed, it creates a wireless “geo-fence” with a 500-meter radius. If the boat moves outside this fence, the device uses Inmarsat-based GPS satellite technology to monitor the boat’s location. The device can notify up to 10 people by e-mail and text message with the boat’s latitude and longitude, speed and heading.
