JRC Jan 901b Ecdis Marine Radar

The JRC JAN-901B is an IMO-compliant navigation system featuring a large 23.1-inch high-resolution display. It is designed to handle the intense processing requirements of modern digital navigation, including high-speed chart redrawing and simultaneous display of AIS and ARPA targets. The system is built around a modular architecture, with a dedicated central processing unit (CPU) and a robust keyboard/trackball control unit that allows for precise operation even in heavy seas. The JAN-901B is particularly famous for its user-friendly interface that mimics JRC’s radar controls, making it easy for bridge officers to transition between systems. It supports a wide range of chart formats, including S-57, S-63, and C-MAP, and offers a comprehensive suite of route planning and monitoring tools that ensure the vessel stays within safe navigational parameters at all times.
