Description

The easyRX3 is a versatile, high-performance AIS (Automatic Identification System) receiver tailored for both marine coastal monitoring and specialized VHF (Very High Frequency) surveillance. Its dual-channel capability, integrated GPS, multiple data outputs, rugged build, and IP67 rating position it as an excellent solution for maritime authorities, coast guards, ports, and maritime service providers.

Specifications

Core Receiver Specs

• Pre-installed AIS decoding software; supports VDM messages (AIS sentences)

• Logs AIS and GPS data to internal flash.

• Records can be accessed/configured via USB without external power

 

Highlights

•  2 Channel AIS receiver
• VHF frequencies free programmable for proprietary closed user group“ by special request to manufacturer
• LAN (RJ45) Output for server connectivity and WiFi connectivity (optional)
• NMEA2000, NMEA0183 and USB port connectivity
• Internal VHF splitter
• Integrated Multiplexer for further external data with different Baud rate
• Internal data logging on Flash memory

Use Cases

• Coastal receiver station: install at high points and stream live Automatic Identification System data to headquarters or networked systems.

• Local “closed-user-group” monitoring: tune to private VHF channels to track specialized traffic. Ideal for port operations, fisheries, pilot boats.

• Compatible with marine electronics (chart plotters, bridge systems) via NMEA2000
