AIS Portable Tracker


AIS Tracker

Safe Navigation via Advanced AIS Functions

i-ais-TRK is a portable Class B AIS Transponder which improves the safety of navigation by assisting in the efficient navigation of ships and small craft, protection of the environment and operation of Vessel Traffic Services (VTS).

i-ais-TRK is a compact device that internally integrates VHF / GPS antennas and a re-chargeable battery. It provides 2 to 5 Watt adjustable VHF output which gives the best accessibility / availability for fishing vessels and boats.

In addition to standard Class B CS features, i-ais-TRK has advantageous functions that can be required by local authorities. It generates and transmits alarm messages according to pre-defined zones and rules (i.e. entering a prohibited zone, over-speed in a defined area); automatically switches to high power output (5W) mode for pre-defined regions (i.e. wide range inland sea) and Search and Rescue (SAR) events and provides black box feature for analysis of past events.

Thanks to its modular structure, i-ais-TRK can easily be adapted for portable or fixed operation by means of optional external antenna and power kits.
