Over the Horizon AIS Monitoring - SM1680

Overview

The SM1680 achieves over the horizon 200 NM* EEZ AIS monitoring from a shore station.

With four synchronized receivers on each AIS channel, the SM1680 is a Software Defined Radio (SDR) that utilizes troposcatter to achieve extended-range Exclusive Economic Zone (EEZ) AIS monitoring without the cost, latency, or other limitations of satellites.

*Individual site performance will vary based on factors such as elevation, topography, and interference.
