SI-TEX MDA-1 Metadata Class B AIS Transceiver w/Internal GPS - Must Be Programmed

The SI-TEX MDA-1 Metadata Class B AIS Transceiver with Internal GPS is a professional-grade marine safety and vessel tracking system engineered for commercial fishing fleets, cargo vessels, law enforcement maritime operations, and coast guard applications. This Class B transceiver meets international maritime safety regulations and provides real-time automatic identification system (AIS) transmission, enabling vessels to broadcast position, speed, course, and vessel identification to other ships and shore-based monitoring stations. Built for operators who demand reliable vessel identification and collision avoidance in high-traffic waterways and open ocean environments.

This transceiver integrates an internal GPS receiver that continuously calculates vessel position and feeds navigation data directly into AIS broadcast packets without requiring external positioning hardware. The Class B designation indicates compliance with International Maritime Organization (IMO) standards for mid-sized commercial and government vessels, transmitting on dual VHF maritime frequencies with sufficient power output for reliable coastal and offshore coverage. Measuring 6 x 5 x 8 inches and weighing only 1.6 lbs, the compact form factor allows flexible mounting in pilothouse, bridge, or protected equipment enclosures while maintaining full RF performance through standard marine antenna connections.

Maritime professionals, harbor patrol units, fisheries enforcement teams, and vessel operators benefit from the MDA-1's real-time AIS transmission capability, which significantly reduces collision risk in congested shipping lanes and enables rapid vessel location during search and rescue operations. The unit requires initial programming to configure vessel call sign, IMO number, and maritime mobile service identity (MMSI) before deployment—a one-time setup performed by qualified marine electronics technicians or the vessel operator. Compatible with standard marine 12/24 VDC power systems and existing VHF antenna infrastructure, installation integrates seamlessly into both new construction and retrofit applications across commercial and government maritime fleets.
