The format of its sending information is consistent with the AIS system. Determine the current accurate position and time information of the vessel by receiving GPS signals, and periodically transmit signals to the AIS system to report the accurate position of the vessel in distress. The products meet the IEC 61097-14 agreement and IMO MSC.246 (83) resolution. Package List: 1 x SART Radar 1 x Instruction1 x Bag of Screw
