JMA-900B series performance features
Unique features
The new JMA-900B chart radar combines JRC's renowned radar and highly advanced ECDIS technology, providing reliable performance and significantly improves situation awareness.
ConstaviewTM
True Trails
ConstaviewTM refreshes the image every 16mS. Despite heading changes trails are always true.
ConstaviewTM
The second generation and patented ConstaviewTM is realised through the use of two high-speed processors (in-house TornadoTM technology). [. . . ] Also, it is easy to active, deactivate and switch between AIS target symbols. This simply can be done with an integrated AIS filter, prioritising the targets within a dedicated area.

Advanced route planning
The advanced nature of JRC's new chart radar system allows route planning in different ways. Either plan your route by using the table editor, while displaying current waypoint or graphically draw your next waypoint on the chart. Dedicated menus are readily available to assist the mariner in effective route planning. Not only can you save the routes, but import favourite or commonly used files, even from previous ECDIS models, using industry standard CSV format. During the voyage, you can add an alternative route, which can be displayed simultaneously. You can move, insert, add and delete waypoints instantly and easily exchange the alternative route with route in progress, at your own convenience.

Multi-view
Multiple and wide screen viewing is possible with the new JMA-900B. You can divide the chart screen into two sections, in which the same or different charts can be displayed. There is also a `look-ahead' capability, especially useful in coastal areas. With the wide screen view function, an additional screen in the display area shows a segment of the chart, allows viewing at a glance.
Interswitching
Optional interswitching to JMA-900B and JMA-9100 series radar.
with optional I/S PCB
JRC also produces special interswitch boxes that allow interswitching up to 8 (chart) radars.
