Unified Planning and Interconnection Design for Shipboard Communication, Navigation, Monitoring and Management Equipment Shipboard communication, navigation, monitoring and management equipment adopts unified planning, layout and interconnection design, which is mainly divided into seven core systems: - Navigation system (including ECDIS, radar, GNSS, etc.); Communication system (with GMDSS as the core);Internal communication system; External communication system (satellite such as VSAT and offshore network);  Monitoring and control system (VDR, CCTV, etc.); Integrated display system (centralized console, BAM, etc.);  Power redundancy system. Its core advantages are as follows: unified interface protocols and strong compatibility; centralized and efficient installation, commissioning and after-sales services; optimized procurement and training costs; high compliance with regulations such as IMO/SOLAS; and outstanding convenience in later expansion and software upgrades.
