The new JMA-900B chart radar combines JRC’s renowned radar and highly advanced ECDIS technology, providing reliable performance and significantly improves situation awareness.
The second generation and patented Constaview™ is realised through the use of three high-speed processors (in-house Tornado™ technology). All info gathered by the radar is fully processed within a few milliseconds before displayed, generating a smooth image rotation when sailing in Head-Up mode. When changing to North-Up, the new radar image is displayed without any delay caused by the scanner rotation. Constaview™ works in radar mode. In chart-radar mode, radar images are displayed with regular intervals.
SELECT A TRAIL LENGTH
Other ship’s movement and speed can be monitored from length and direction of their trails, primary serving for collision avoidance. The JMA-900B series integrate three different trail length modes, that will show a ship’s course instantly, a unique operational feature that allows for more flexibility. Example real-time processing on the left.
The AIS is an important key device used to indicate AIS target symbol and information. These targets are very useful, as it provides the maneuvering conditions of other ships at a glance, allowing for safe and effective navigation. The name of the vessels, and bearing, range, speed, length, heading and much more AIS target specifics from other ships are received and displayed. The AIS symbols are continuously displayed on-screen without the influence of the radar characteristics. The AIS targets are never shielded by ground, rain or cloud reflections, nor are they eliminated by adjustments of anti-sea or anti-rain clutter.
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.
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.
