GPS-20A GPS Sensor

Parallel 18-channel receiver capabilities and compatibility with SBAS (WAAS / EGNOS)


  • SBAS compatibleIn addition to positioning via standard GPS, you can also access high precision positioning data via SBAS (WAAS / EGNOS). This sensor can be connected to the GTD-110/150 chart plotter, the CVG-80/200 plotter sounder or the K-Link System to enable precision DGPS navigation.The increasingly precise positioning data will help you improve safety at sea and locate fishing spots.
  • 18-channel receptionThis sensor incorporates a parallel 18-channel receiver to enable fast, accurate positioning.
