Sitex SAS-300 Class B SODTMA AIS With External GPS Antenna

The Sitex SAS-300 Class B SODTMA AIS with External GPS Antenna is a professional-grade marine navigation and vessel tracking system designed for tactical and maritime law enforcement, Coast Guard, and military maritime operations. Built to Class B specifications under SODTMA standards, this system delivers reliable automatic identification and precise positioning in high-demand operational environments where vessel tracking, inter-agency coordination, and real-time situational awareness are mission-critical.

This AIS transceiver operates on dual VHF channels, transmitting vessel identity, position, course, and speed data automatically to other equipped vessels and shore-based monitoring stations. The integrated external GPS antenna ensures accurate position fixes in open water and coastal navigation zones, even in GPS-challenged environments where internal antennas may struggle. Weighing 7.05 pounds, the SAS-300 is engineered for compact installation aboard patrol boats, tactical response vessels, and command centers where space and weight efficiency directly impact operational agility. Class B compliance ensures interoperability with both commercial shipping traffic and government maritime networks without interference or signal degradation.

Maritime law enforcement, Naval Security Teams, and tactical boat operators benefit from the SAS-300's seamless integration into existing vessel communication suites. The external GPS antenna installation requires a clear line of sight to the sky and is compatible with most standard antenna mounts found on fast-attack craft and patrol vessels. Installation demands basic marine electrical knowledge and proper VHF antenna placement to optimize transmission range—typically 10–20 nautical miles depending on antenna height and atmospheric conditions. This system is ideal for agencies managing high-speed interdictions, coastal security, and joint task force operations requiring persistent vessel identification and position tracking.
