Description
AIS Transceiver
The HS-MX6208GT is a fully-featured AIS black box terminal that combines a high-performance transceiver with a built-in GNSS receiver. Delivering both 2W (CSTDMA) and 5W (SOTDMA) power modes, it’s the core solution for vessel tracking, smart AtoN, and maritime safety applications.
Features and Specifications
- Built-in a high-precision positioning system, expandable to support Beidou-3 short message data transmission.
- Utilizes a high-performance dedicated AIS signal processing SoC chip.
- Integrated full-protocol stack Class B and B+ AIS transponder.
- Supports 2W CSTDMA and 5W SOTDMA low and high-level output power.
- Excellent sensitivity down to -119dBm for receiving long-range vessels and other AIS information.
- Compliant with the technical requirements of AIS Type I/II/III buoy products.
- Supports automatic reception and rapid processing of transmissions from other vessels, VTS shore stations, airborne, and satellite AIS.
- Receives and parses position, heading, speed, and other data, encapsulating it in standard AIS message formats.
- Compliant with IEC 60945, IEC 62287-1/2, IEC 61162-1/2, IEC 61108-1/2, IEC 62320-2, and ITU-R M1371-5 standards.
- Ultra-compact dimensions (144mm x 64mm x 50mm), ideal for miniaturized, multi-functional AIS applications.

FAQs
No, the HS-MX1203GT module itself does not have a built-in GPS. It requires an external active GPS/BeiDou antenna connected via its MCX-female connector to obtain its own position, which is essential for transmitting AIS messages.
The module ships with generic factory settings. You must configure it with your vessel's specific MMSI number, name, and call sign using our provided AIS CONFIGURATION PC software and a TTL-to-USB adapter cable. Once configured, these details are stored in the module.
Yes. The module features a SILENT pin. By pulling this pin low (to GND), you can disable AIS transmission for privacy or in security-sensitive areas while continuing to receive AIS data from other vessels.
You need two separate VHF antennas:
A dedicated GPS/GLONASS/BeiDou active antenna for the GPS port.
Using high-quality, properly installed antennas is critical for optimal performance.
A dedicated AIS VHF antenna for the VHF port.
Yes. We provide comprehensive documentation for integrators, including:
