Garmin’s two new GPS antennas — the GPS 19x HVS ($199.99) and the GPS 19x NMEA 2000 ($249.99) — provide up to 10-hertz update rates for position, velocity and time data. These 32-channel receivers can track multiple Global Navigation Satellite System satellites, including GPS and GLONASS. With more visible satellites, the WAAS-capable antennas offer more-accurate fixes to within 3 meters, Garmin says. GPSMAP 6000 and 7000 series multifunction displays have been optimized to use the 10-hertz information. Call 913‑397‑8200 or visit www.garmin.com.
