RTK GNSS Antenna MMW-4820

The MMW-4820 is a premium marine-grade RTK (Real-Time Kinematic) GNSS (Global Navigation Satellite System) antenna engineered to deliver uncompromised centimeter-level positioning accuracy for demanding offshore, coastal, and blue-water maritime applications. Building on advanced signal processing and ruggedized marine design, it addresses the unique challenges of open-ocean and harsh coastal environments—including extreme salt exposure, high winds, heavy seas, and intense electromagnetic interference (EMI) from shipboard systems—making it a reliable choice for mission-critical marine operations.
