Garmin GPS 19x HVS NMEA 0183
Garmin GPS 19x HVS NMEA 0183 — Product description
Unlock Superior Navigation Precision on the Water
Equip your vessel with the Garmin GPS 19x HVS NMEA 0183 receiver, a powerhouse designed for marine enthusiasts who demand unwavering accuracy in even the toughest conditions. This compact yet robust antenna delivers position, velocity, and time data at blistering 10 Hz update rates—ten times faster than standard units—ensuring your chartplotter or multifunction display (MFD) renders smooth, real-time tracking whether you're cruising at high speeds or maneuvering slowly through tight harbors.
What sets it apart? Its 32-channel architecture locks onto a broad array of satellites from GPS, GLONASS, Galileo, and QZSS networks. This multi-constellation support means fewer dropouts and pinpoint fixes, even under partial sky views like dense foliage or urban waterways. WAAS enhancement narrows your location down to within 3 meters, transforming guesswork into confidence-boosting navigation.
Experience Smoother Tracking and Heading at Any Speed
Traditional GPS units often falter at low speeds, causing erratic jumps in position and course data below 1 mph—frustrating when anchoring or approaching waypoints. The GPS 19x HVS eliminates this jitter, providing a rock-steady heading that mirrors your boat's true orientation. Coming out of sharp turns? No more lag or skipping; it maintains fluid positioning through arcs, giving you the edge in precision docking or competitive racing.
At higher velocities, the rapid 10 Hz refreshes paint your trail on the screen without blurring or gaps, ideal for offshore passages where every knot counts. Mariners report it revolutionizes autopilot performance, holding courses tighter and responding quicker to wind shifts or currents.
Seamless Integration for Any Boat Setup
Rugged IPX7 waterproofing laughs off saltwater spray, rain, and submersion, while flexible mounting options adapt to your deck design. Pole-mount for elevated views, flush-mount for sleek profiles, or tuck it under fiberglass hulls for a hidden install that preserves aesthetics and aerodynamics.
Customization shines with selectable update rates (1 Hz, 5 Hz, or full 10 Hz), tailoring output to match your system's needs via the included select cable. The NMEA 0183 protocol ensures plug-and-play compatibility with Garmin's marine ecosystem, including instrument displays and autopilots from the 4000 through 7000 series and beyond. Power/data cable simplifies wiring, minimizing clutter in tight console spaces.
- Pole mount: Optimal for open cockpits with clear sky access.
- Surface mount: Perfect for flat deck areas.
- Under-deck mount: Discreet below fiberglass for radar-free zones.
Why Boaters Choose the GPS 19x HVS for Everyday Adventures
Whether chasing trophy fish in coastal inlets, plotting multi-day cruises across open bays, or teaching new crew members to navigate safely, this receiver steps up. Its high-sensitivity tech punches through obstructions better than legacy antennas, while the enhanced heading data feeds accurate autopilot corrections—saving fuel and reducing skipper fatigue on long hauls.
Fishermen love how it stabilizes marks over structure, preventing drift errors during drifts. Sailors appreciate the true wind-relative headings for tactical tacking. And for commercial ops, the reliability cuts downtime, keeping schedules on track.
"Switched to the 19x HVS and my plotter finally tracks like it's glued to the water—night and day difference in tight marinas."

Keep It Performing Like New
A quick rinse with fresh water after salty outings prevents corrosion. Inspect cable connections seasonally for wear, and ensure firmware stays current for emerging satellite support. Avoid obstructing the hemispheric view with metal gear nearby to maximize satellite locks.
Frequently Asked Questions

This 32-channel receiver tracks GPS, GLONASS, Galileo, and QZSS for robust coverage and accurate fixes in challenging environments.
How accurate is the position data from this receiver?
WAAS-capable performance provides locations within 3 meters (9.84 feet), with enhanced stability at all speeds.
What mounting options are available for the GPS 19x HVS?
Includes pole, surface, and under-deck mounts, plus IPX7 waterproofing for versatile, durable installation on any vessel.
Is the GPS 19x HVS compatible with older Garmin chartplotters?
Yes, it integrates seamlessly via NMEA 0183 with Garmin marine displays and autopilots from the 4000, 5000, 6000, and 7000 series.
Can I adjust the update rate on this GPS antenna?
Absolutely—configure for 1 Hz, 5 Hz, or 10 Hz using the included update rate select cable to match your setup.
What's included in the package?
GPS 19x HVS unit, pole mount, surface mount, under-deck mount, power/data cable, update rate select cable, and documentation.
The 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 instruments, autopilots and multifunction displays.
Delivers Precise Location Data
This 32-channel receiver is capable of tracking multiple global navigation satellite systems, including GPS, GLONASS, Galileo1and QZSS1. 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).
Observable Advantages
Compared to units with slower update rates, the GPS 19x offers dramatic improvement when used at low speeds. Position and course information from slower units can jitter and swing considerably at speeds below 1 mph. The GPS 19x provides a consistent and smooth heading which is especially important when trying to hit a specific waypoint or mark.
The GPS 19x also reflects the true boat heading smoothly and accurately. This is especially evident when coming out of turns. And, the GPS 19x eliminates position skipping that can occur at low speeds and when turning the boat in an arc. The GPS 19x maintains a smooth position throughout the turn2.
Built for Versatility
Part of the Garmin marine instrument family, the GPS 19x HVS is built to withstand the elements. This waterproof (IPX7) sensor can be pole mounted or flush mounted. It also can be attached to the underside of many fiberglass decks for added ease of installation. In addition, it also can be configured to have 1 Hz or 5 Hz update rates to help support specific installation requirements.
