How It Works

Receive test confirmations in seconds

406Link works by sending a specially encoded test signal 22,000 miles up to the Cospas-Sarsat satellites. Once the satellites receive the signal, it is then picked up by our ground stations in North America.  Within seconds, our patented software processes your self-test data and a confirmation message is then sent to you and/or your contacts by email and/or SMS text message.

When performing a GPS self test (for Plus subscriptions only), your GPS coordinates are then plotted on a map and 406Link includes a link in your email and/or SMS text message clearly showing your location to within 110 yards (100 meters).
