Features

The JMA-2300MK2 continues the success of its predecessor, utilizing the latest digital signal processing for excellent target identification and detection in a compact design including all-new designed scanners.

System-on-Chip

JRC engineers custom designed the System-on-Chip (SoC) inside the new JMA-2300MK2 series to be an extremely powerful tool.
With such a small chip, weighing less than a sugar cube, performance remains at out high standards. At the same time, the SoC technology makes the compact radar very power efficient.

AIS and MARPA+

The new radar has the ability to display 50 AIS symbols, and 10 MARPA+ tracking targets as standard. The high quality of the display provides outstanding target definition and discrimination.
The (second generation) MARPA+ continues JRC’s successful MARPA+ technology first found in the previous JMA-2300 radar series. Our engineers continued developing and improving the technology, until now, with MARPA+, manual or automatic target tracking is even more reliable.

DirecTrak

The new radar has an easy vessel searching function based on AIS, called DirecTrak. This function shows the nearest 50 vessels received by the AIS. If you select a vessel on the list, then range and bearing is displayed of the selected vessel.

Semi-Constaview

Based on JRC’s patented technology found in the bigger radars, the new JMA-2300MK2 integrates Semi-Constaview.
This allows fast processing of targets, showing true trails in Head-Up mode, without interference of fixed targets, such as land or mass.

Soft keys

The display unit incorporates 4 soft keys, just below the display jma2300mk2interfacing_softkey corresponding to the most used functions of a specific operation using the multi key. You instantly see the options you have, without loosing the sight of the radar picture.

Cursor key

The cross key is a multi functional add on to the display. Move the cursor and go through menus.

Languages

This JMA-2300MK2 radar series supports the English, Japanese, Chinese, Korean, Spanish, Portuguese, French and Norwegian.
