JRC Alphatron

JMA610 River Radar

With the introduction of the JMA 610 river radar, Alphatron Marine presents the next-generation of the highly successful JMA 609, of which more than 2000 have been in service since its introduction in 2004. The JMA 610 has many of the characteristics of the JMA 609. After all, why mess with a good thing! Still, the engineers of Alphatron and JRC have succeeded in adding functions that are actually useful. The photoshot® and AIS functionalities, in particular, are two exceptional additions to this radar, a navigation centre that is considered the best of its kind.But operator feedback has also inspired changes that have further improved image quality and ease of use.

All electronics, the compact flash card and radar processors are fitted in a black box unit connected to the display, the control unit and the various sensors. The blackbox’s small dimensions make it easy to fit on board. NMEA sentences coming from the various sensors are being used. Inputs for rate of turn, rudder indicator and autopilot are galvanically isolated.
