Why Choose the R550Ni?
Unlike standard AIS receivers that simply forward raw AIS data to a connected PC, the R550Ni combines high-sensitivity AIS reception with powerful onboard computing, enabling it to filter, log, and distribute data independently. It is ideal for deployments in professional environments such as coast guard stations, port authority control towers, search-and-rescue coordination centers, or private AIS networks.
Whether you’re building a centralized maritime domain awareness system, expanding AIS coverage into remote areas, or upgrading a volunteer-operated AIS station, the R550Ni delivers unmatched versatility and value.
