The highly accurate GPS 19x NMEA 2000 position receiver/antenna provides 10 Hz update rates for position, velocity and time data. It offers high-sensitivity reception and enhanced position acquisition to the Garmin family of marine multifunctional displays (MFD), instrument display and autopilots. This 32-channel receiver is capable of tracking multiple global navigation satellite systems, including GPS, GLONASS, Galileo and QZSS. Since more satellites are visible, it can provide more accurate fixes in challenging conditions. With its enhanced position, heading and speed accuracy delivered 10 times more often than other receivers/antennas, it provides smoother drawing of your position on the chartplotter/MFD at higher speeds.
