Garmin NMEA 0183 GPS antenna

32-channel 10Hz receivers that detect the GNSS, GPS, GLONASS, Galileo and QZSS satellite systems at the same time thus supplying more accurate position data even in limited reception areas. These high-performance antennas supply position, heading and speed data to all chartplotters/MFD at an updating frequency ten times as faster as traditional GPS antennas. 19x GPS antennas are compatible with the WAAS and EGNOS systems and supply extremely accurate position information in a 3-m range.
