Fish Ship Positioning(Base Station)
Easy base station equipment, designed according to actual need of AIS data monitoring, is accordance with AIS system. It greatly saves system's whole cost on the basis of realizing monitoring.

Main function
1, Finding out hidden danger in time
In area covered by shore-based base station or ocean mobile base station, information of all vessels equipped with AIS will be received by base station. System will get vessel's running state by contrasting information frequency and state data. Not receiving information for a while suggests there is hidden danger in this vessel. Under this situation contact captain and vessel owner to know all the circumstances immediately. SOS message can be received through base station which makes rescue action can be carried out in time.
2, Convenient information management system
Related information about vessel can be received through AIS base station network. On the one hand this information can be taken as data source of judgment of in-time disposal, on the other hand they are saved in database for system analysis or basis of accident disposal.

Main features
1. Compatible with current marine system's AIS standard base station and AIS shipborne equipment;
2. Receiving without sending will not expose base station, which makes base station placement easier;
3. Build-in stabilized voltage supply (AC/DC optional) meets different environment requirement;
4. RS232 interface makes output data stable and reliable.
