Advanced Class B AIS Transceiver with SOTDMA Technology

The Sitex SAS-600 Class B AIS is a cutting-edge marine transceiver designed for enhanced safety and superior network priority on the water. Featuring advanced SOTDMA technology, this AIS unit ensures your vessel remains visible in congested commercial harbors and open waters alike. With a powerful 5-watt transmission output—more than double that of traditional Class B AIS units—the SAS-600 extends your vessel's detection range, improving situational awareness for safer navigation.

This high-performance AIS transceiver integrates seamlessly with onboard systems through NMEA-0183 and NMEA-2000 connectivity, offering compatibility with modern bridge electronics. A built-in Wi-Fi module allows AIS and position data to be wirelessly transmitted to connected devices. The unit's intuitive 5.7-inch full-color LCD display remains clearly visible in all lighting conditions, ensuring vital navigation data is easily accessible at all times.

Powerful 5-Watt SOTDMA Transmission

Unlike traditional Class B AIS units, the SAS-600 utilizes Self-Organizing Time Division Multiple Access (SOTDMA) technology, giving it the same transmission priority as commercial Class A AIS transceivers. This guarantees your vessel’s AIS signals are transmitted reliably, even in high-traffic maritime environments. The 5-watt transmission power significantly extends the range at which other vessels and AIS tracking systems can detect your position.

Seamless Connectivity and Navigation Integration

Designed for integration with modern marine electronics, the SAS-600 features multiple NMEA-0183 ports and NMEA-2000 compatibility, allowing it to connect to virtually any onboard system. Additionally, its built-in Wi-Fi capability enables AIS and positioning data to be sent wirelessly to compatible devices.

With support for C-Map Max cartography, the SAS-600 provides detailed charting and navigation assistance. A built-in GPS and GLONASS receiver, paired with a commercial-quality external GPS antenna, ensures accurate location tracking and reliable position updates.

Rugged Design for Marine Environments

The SAS-600 is built to withstand harsh marine conditions, with an IPX6 and IPX7-rated waterproof and weatherproof construction. Whether mounted on an exposed deck or within a protected bridge, this unit delivers reliable performance in any maritime environment. Its user-friendly interface features a multi-lingual menu system, ensuring intuitive operation for all users.
