The HVS (High Velocity Start) technology enables rapid satellite acquisition — even in challenging signal environments like marinas with tall masts, bridges, or tree-lined waterways.\u003c\/p\u003e\u003cp\u003eWith a 10 Hz position update rate, it feeds position data ten times per second — fast enough for responsive autopilot steering and accurate track logging at speed. The wide voltage input (8–40V DC) makes it compatible with both 12V and 24V electrical systems, and the IPX7 waterproof rating means it can be mounted in exposed locations without concern.\u003c\/p\u003e\u003cp\u003eThe included 15-metre cable provides plenty of reach from a mast or hardtop mount to the helm electronics.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: External GPS\/GNSS antenna with NMEA 0183 output\u003c\/li\u003e\n\u003cli\u003ePosition Update Rate: 10 Hz\u003c\/li\u003e\n\u003cli\u003eOutput Protocol: NMEA 0183 (4800 baud)\u003c\/li\u003e\n\u003cli\u003eCable Length: 15 metres (included)\u003c\/li\u003e\n\u003cli\u003eWaterproof Rating: IPX7\u003c\/li\u003e\n\u003cli\u003eInput Voltage: 8–40V DC (12V and 24V compatible)\u003c\/li\u003e\n\u003cli\u003ePart Number: 010-01010-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The GPS 19x HVS is the right choice when your chartplotter, autopilot, or VHF radio needs an external GPS source — either because the device lacks a built-in GPS receiver, or because the internal antenna has poor sky view from its helm location. It’s also a reliable solution for feeding a single GPS position source to multiple devices via an NMEA 0183 multiplexer. The 10 Hz update rate makes it particularly well-suited for autopilot applications where slow position updates cause hunting or course correction lag. Confirm your device accepts NMEA 0183 input (not NMEA 2000) before ordering — if your network is NMEA 2000, you’ll need a different antenna or a protocol converter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMounting Note:\u003c\/strong\u003e Mount with a clear, unobstructed view of the sky. Avoid locations directly below a radar dome or in the shadow of a mast, as these can degrade GPS signal acquisition.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eEstimated Packaging: Box approximately 8\" × 6\" × 4\" (20 × 15 × 10 cm), approx. 0.4 kg shipped.\u003c\/em\u003e\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43943846608932,"sku":"GAR-010-01010-00","price":261.89,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/01dd816d-abf6-4d65-9e71-41a32f20ae0c.png?v=1783983905","url":"https:\/\/marisolmarine.com\/products\/garmin-gps-19x-hvs-high-sensitivity-gps-antenna-nmea-0183","provider":"Marisol Marine Company","version":"1.0","type":"link"}
