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.
