The Garmin GPS 19x HVS brings high-sensitivity NMEA 0183 positioning to marine electronics setups that demand reliable, fast-updating GPS data. A selectable 10 Hz update rate refreshes position, velocity, and time data up to ten times more frequently than standard 1 Hz receivers, producing a noticeably smoother track on connected chartplotters — even at slow trolling speeds or through tight turns where lower-rate units tend to skip or jitter. With 32-channel multi-constellation support and WAAS-aided accuracy, it integrates cleanly with Garmin marine instruments, autopilots, and multifunction displays.

Specifications:

• 32-channel receiver supports GPS, GLONASS, Galileo, and QZSS (Galileo and QZSS supported when available; software update may be required)
• Selectable update rates: 1 Hz, 5 Hz, or 10 Hz for position, velocity, and time
• WAAS-capable position accuracy within 3 m (9.84 ft)
• High-sensitivity reception with enhanced position acquisition
• Smooth, consistent heading output — especially effective at low speeds and through turns
• Eliminates position skipping during slow-speed operation and arc turns
• Waterproof rating: IPX7
• Mounting options: pole mount, flush mount, or underside of fiberglass deck
• Compatible with Garmin marine instruments, autopilots, and MFDs; GPSMAP 6000/7000 series and newer chartplotters fully optimized for 10 Hz data
• Interface: NMEA 0183
