The Furuno GP340 represents a breakthrough in accessible marine navigation technology—a 75-channel GNSS receiver engineered to eliminate guesswork from vessel positioning. Built for fishing fleets, commercial operators, and survey professionals, this compact system tracks signals across five global satellite constellations simultaneously, ensuring reliable fixes even in challenging coastal or inland environments.
Why Choose the GP340?
With a 10 Hz update rate and sub-3-meter accuracy, the GP340 keeps your vessel’s position current and precise. Its multi-constellation architecture (GPS, GLONASS, Galileo, QZSS, and BeiDou) means you’re never dependent on a single satellite system. Add regional SBAS augmentation (WAAS, EGNOS, MSAS, GAGAN), and your positioning becomes even sharper in supported areas.
The receiver integrates seamlessly with existing marine electronics through dual NMEA format output—NMEA2000 native or optional NMEA0183 cable for legacy systems and NavNet-based solutions. Installation is straightforward with included mast and deck-mount hardware; the supplied 6-meter NMEA2000 cable connects directly to your vessel’s network.
Efficient 12-24 VDC operation and a rugged marine-rated enclosure mean the GP340 runs reliably through seasons of saltwater exposure.
