By receiving differential correction signals from ground-based beacon stations, it significantly improves positioning accuracy beyond standard GPS — delivering sub-metre precision that makes a meaningful difference in tight harbour approaches, survey work, and any application where precise position matters.\u003c\/p\u003e\u003cp\u003eDGPS (Differential GPS) and DGLONASS (Differential GLONASS) corrections work by comparing the GPS\/GLONASS signal received at a known fixed reference station with the expected signal, then broadcasting the correction data to nearby receivers. The GPA023S picks up these corrections and feeds them to the GP-1700, resulting in position accuracy that standard GPS alone cannot achieve.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: DGPS\/DGLONASS correction antenna\u003c\/li\u003e\n\u003cli\u003eCompatible Unit: Furuno GP-1700 GPS navigator\u003c\/li\u003e\n\u003cli\u003ePositioning Accuracy: Sub-metre (with DGPS correction signal)\u003c\/li\u003e\n\u003cli\u003eWaterproof: Yes — suitable for exposed mounting\u003c\/li\u003e\n\u003cli\u003ePart Number: GPA023S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The GPA023S is the right antenna when you’re operating a Furuno GP-1700 and need the highest positioning accuracy available from that system. It’s particularly valuable for commercial fishing vessels, survey boats, and operators working in confined waterways where sub-metre accuracy improves safety and operational precision. DGPS correction signals are broadcast by coast guard and maritime beacon stations — coverage is strong in most coastal areas of Canada and the US, but confirm beacon coverage in your operating area before relying on DGPS corrections offshore. This antenna is specific to the GP-1700 and is not a universal DGPS antenna — confirm your unit model before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMounting Note:\u003c\/strong\u003e Mount with a clear sky view and away from radar domes and other RF sources. The antenna must be within range of a DGPS beacon transmitter to receive correction signals.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eEstimated Packaging: Box approximately 10\" × 8\" × 4\" (25 × 20 × 10 cm), approx. 0.6 kg shipped.\u003c\/em\u003e\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43943846281252,"sku":"FUR-GPA023S","price":1064.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/4061d948-7c20-4443-9832-7399b9206a53.png?v=1783990600","url":"https:\/\/marisolmarine.com\/products\/furuno-gpa023s-dgps-dglonass-antenna-gp-1700","provider":"Marisol Marine Company","version":"1.0","type":"link"}
