The second generation and patented Constaview™ is realized through the use of three high-speed processors (in-house Tornadoェ technology). All information gathered by the radar is fully processed within a few milliseconds before being displayed. A smooth image rotation is generated 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.

True Trails


Constaview™ refreshes the image every 16mS. Despite heading changes trails are always true.

Relative Trails

Traditional technology relies on several sweeps of the scanner to redraw the image.
Trails are presented as relative.

Target Enhancement Function™

Developed exclusively by JRC, TEF™, allows target enhancement relative to the target size. The smaller echoes are far more enlarged than bigger echoes, giving a better on-screen separation and identification.

Select a trail length

Others ships movement and speed can be monitored from length and direction of their trails, primary serving for collision avoidance. The JMA-9172-SA integrates three different trail length modes, that will show a ship's course instantly. A unique operation features that allows for more flexibility. Example:
