Garmin GPS19x HVS 10Hz 32 Channel GPS Antenna with NMEA0183 Output

Garmins highly accurate GPS 19x HVS position receiver/antenna provides up to 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 up to 10 times more often than other receivers/antennas, it provides smoother drawing of your position on the chartplotter/MFD at higher speeds. WAAS-capable, it can determine your precise location to within 3 m (9.84 ft). (Typical WAAS position accuracy)
