Furuno GPA023S β€” DGPS/DGLONASS Antenna for GP-1700

The GPA023S is a DGPS and DGLONASS antenna designed for the Furuno GP-1700 GPS navigator. By receiving differential correction signals from ground-based beacon stations, it significantly improves positioning accuracy beyond standard GPS β€” delivering sub-metre precision that makes a meaningful difference in tight harbour approaches, survey work, and any application where precise position matters.

DGPS (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.

Key Specifications

  • Type: DGPS/DGLONASS correction antenna
  • Compatible Unit: Furuno GP-1700 GPS navigator
  • Positioning Accuracy: Sub-metre (with DGPS correction signal)
  • Waterproof: Yes β€” suitable for exposed mounting
  • Part Number: GPA023S

Parts Desk Insights

Best Use Case: 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 β€” 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 β€” confirm your unit model before ordering.

Mounting Note: 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.

Estimated Packaging: Box approximately 10" Γ— 8" Γ— 4" (25 Γ— 20 Γ— 10 cm), approx. 0.6 kg shipped.
