Model 86634 GPS 19x HVS 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. 1Supported when available. A software update may be required. 2The GPSMAP 6000 series, 7000 series and newer chartplotters have been optimized to fully use the 10 Hz information from the GPS 19x.
