Koden GPS-20A

The Koden GPS-20A GPS receiver is a high-tech device that provides excellent accuracy thanks to the support of SBAS systems, including WAAS, MSAS and EGNOS. This guarantees exceptional data accuracy, which is critically important for maritime navigation. NMEA 0183 compatibility allows navigation data to be transmitted to a wide range of external equipment such as radar stations, electronic mapping systems and echo sounders, providing an integrated approach to ship management.

A special feature of the GPS-20A model is the ability to integrate with radar systems that support the C-MAP mapping function, for example, with the MDC-2240 and MDC-2960BB models. This allows captains and navigators to get a more complete and visual picture of the area, combining radar data with cartographic information.
