RTK GNSS Antenna MMW-4020

The MMW-4020 is a marine-grade, ruggedized RTK (Real-Time Kinematic) GNSS (Global Navigation Satellite System) antenna specifically engineered to deliver reliable centimeter-level positioning accuracy for marine, coastal, and offshore applications. Built with saltwater-resistant materials, anti-corrosion technology, and advanced signal stabilization, it excels in harsh maritime environments—where exposure to salt spray, high humidity, rough seas, and electromagnetic interference (EMI) from shipboard electronics poses unique challenges to standard GNSS antennas.
