The unique and innovative feature of the Tron AIS-SART is the combination of its physical size and technical capability. The housing of the Tron AIS-SART is identical to Jotron’s radar-SART, type Tron SART20, – that is a total height of 251 mm and a weight of only 450g.  Technically, the Tron AIS-SART is based on the following principals; the unit will be programmed from the manufacturer with a unique ID code and receives its position via an internal GPS antenna. This data is combined and transmitted using the international AIS channels (AIS A and AIS B) in the maritime VHF band.
