GPS Sensor For Marine

GPS Sensor For Marine

Enhanced depth data

The sophisticated “all-in-view” JLR-4340 GPS receiver uses up to 12 satellite signals to pinpoint your exact location. The JRC GPS receiver integrates DGPS measurement via correction data transmitted from the SBAS satellites (WAAS, EGNOS, MSAS), resulting in an even higher accuracy of current position. RAIM functionality is included to assess the integrity of GPS signals in the GPS receiver, assuring higher reliability in global positioning than conventional methods. The NMEA0183 output can be configured as version 1.5, 2.1 or 2.3, thus allowing connection with various types of marine equipment including radars, fish finders and plotters.

Easy installation

The base of the GPS receiver is designed for easy installation, either on to a navigation antenna mount unit or on an extension mast (according to 1” x 14 NPT standards). The antenna base includes a slot allowing for easy cable management, significantly reducing installation time. You can link power supplied by connected GPS navigation equipment, directly to the GPS receiver.
