The HS‑MX1209GT is an ultra‑compact, low‑power AIS (Automatic Identification System) receiver module designed for next‑generation maritime communication, vessel tracking, and unmanned system integration. Based on a high‑performance SDR architecture, it delivers excellent AIS decoding capability with receiver sensitivity down to -112dBm @ 20% PER.
The module integrates dual‑channel AIS receivers and a built‑in 50‑channel GNSS receiver (GPS/Galileo/Beidou optional), enabling precise positioning and reliable AIS message decoding from Class A, Class B, AtoN, airborne AIS, AIS SART, AIS MOB, and EPIRB‑AIS devices.
With its extremely small footprint (44 × 38 × 5 mm) and low power consumption, the HS‑MX1209GT is ideal for compact AIS terminals, beacon lights, AtoN, UAVs, USVs, offshore wind farm systems, and smart maritime IoT applications.
The HS‑MX1209GT offers industry‑leading compactness, excellent sensitivity, and integrated GNSS, making it ideal for space‑constrained AIS devices, unmanned platforms, and next‑generation maritime IoT systems.

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.
What is the default configuration, and how do I program it for my vessel?
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.
Can I temporarily turn off the AIS transmission (Silent Mode)?
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.
What kind of antenna should I use with this module?
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.
