Garmin Cortex-M1 AIS Class B SOTDMA smartAIS Product Description
Enhance your boating safety and peace of mind with a cutting-edge AIS transponder that goes beyond basic tracking. This powerhouse device fuses high-speed SOTDMA Class B transmission with intelligent algorithms to deliver proactive collision warnings, anchor drag detection, and man-overboard responses. Whether you're navigating busy waterways or leaving your vessel unattended, it keeps you one step ahead of potential hazards.
Imagine hearing a clear voice alert like "collision alert, starboard bow" instead of a generic beep—giving you precise direction to react swiftly. Paired with GPS and built-in heading sensors, it broadcasts your vessel's exact position, identity, and course to nearby boats, improving everyone's situational awareness on the water.
SmartAIS: Proactive Collision Avoidance
The heart of this system lies in its smartAIS technology, which continuously scans for threats and escalates alerts until you acknowledge them. It pulls real-time AIS data from surrounding vessels, calculating bearings, relative positions, and closest points of approach. This isn't just passive reception; it's an active guardian that prioritizes your safety with SOTDMA efficiency—self-organizing time-division multiple access ensures reliable, high-priority broadcasts even in crowded channels.
- Voice-annunciated alerts specify threat direction for instant response.
- Integrates heading data for accurate tracking by others.
- Outperforms traditional systems with smarter, context-aware notifications.
Boaters report fewer close calls in high-traffic areas like harbors or race courses, thanks to this forward-thinking design.
Comprehensive Onboard Safety Features
Beyond collisions, stay protected from everyday risks. Anchor drag monitoring uses your actual bow position and environmental changes—like shifts in wind, current, or depth—to trigger alarms if your boat drifts unexpectedly. Man-overboard detection activates manually via app or automatically from compatible beacons, launching a precise track-back mode.
These features shine during overnight anchoring or crewed outings, providing layered protection that integrates seamlessly with your routine.
VHF-Ready Hub for Full Communication
Transform this AIS hub into a complete VHF station by adding a compatible handset. It handles voice channels with dedicated receivers, Class D DSC for distress signaling, and robust power output. The built-in splitter maintains performance without compromising receive sensitivity, making it ideal for vessels needing reliable comms alongside AIS.
Remote Vessel Monitoring and Control
Step ashore without worry. Connect up to five external sensors via the GPIO port to watch bilge levels, security, shore power, and more. Dedicated apps—Cortex Onboard for onboard use and Cortex Monitor for remote access—deliver real-time stats, alerts, and control over lights, AC, refrigeration, and other devices.
With LTE connectivity (region-dependent), cloud integration sends push notifications to your smartphone. Premium plans unlock advanced remote commands, perfect for liveaboards or weekend warriors checking in from afar. NMEA 2000 compatibility shares data across your MFDs and chartplotters for a unified helm experience.

Frequently Asked Questions
What makes SOTDMA Class B better for AIS?
SOTDMA offers self-organized time slots and higher transmit power (5W), ensuring more reliable broadcasts in dense traffic compared to CS variants, with better integration into professional networks.
How does anchor drag detection work?
It references your bow's GPS position and heading sensor, monitoring drifts from wind, current, or depth changes, alerting via app or voice if thresholds are exceeded.
Can I control boat systems remotely?
Yes, via the Cortex Monitor app with cloud connectivity, manage devices like lights or pumps from your phone, plus receive sensor-based alerts anywhere.
Is it compatible with my existing chartplotter?
It supports NMEA 2000 and 0183, outputting AIS, GPS, and MOB data, so it integrates with most modern MFDs for overlay on your screens.
What's the difference between onboard and monitor apps?
Onboard app serves as your helm interface for real-time data and controls while aboard; Monitor app provides remote access and cloud alerts when away.
Does it support man-overboard tracking?
Absolutely—manual activation via app or auto from AIS MOB beacons triggers alarms and track-back navigation to the position.
Garmin Cortex® M1 SOTDMA SmartAIS Transponder with Remote Vessel Monitoring
Model: 010-02815-20- A high-speed smartAIS transponder transmits your boat’s location and heading and proactively warns of certain collision threats.
- In addition to collision alerts, smartAIS will trigger alarms for anchor drag or man overboard situations.
- This hub comes VHF-ready. Simply add a Cortex handset (sold separately) for full VHF radio capability.
- Cortex apps let you monitor boat systems, receive alerts and remotely control devices from your compatible smartphone.
- A GPIO port and supplied cable allow you to monitor bilge pumps, security sensors, shore power and more.
- NMEA 2000® networking allows you to view Cortex data on your connected MFDs and chartplotters.
Cortex M1 is a full Class B SOTDMA transceiver combining GPS, AIS and heading data with smart logic to proactively warn you of certain collision risks with alarms or voice-annunciated alerts that escalate until acknowledged. AIS vessel information (name, bearing and relative position) is continuously provided using AIS information broadcast from other boats.
Using actual anchor position from the bow and the Cortex built-in heading sensor, smartAIS tracks boat movement and sounds an alarm if the anchor drags or if there is a change in wind speed, direction or water depth. While on your boat, get alerts on your compatible mobile device via the Cortex Onboard app — or via the Cortex Monitor app when you’re ashore.
Cortex smartAIS continuously watches for man overboard (MOB) activations, sounding an alarm when it detects one. MOB can be manually activated via the Cortex Onboard smart device app or automatically from an AIS MOB beacon — which launches a track-back mode for quicker retrieval.
In the event of a collision alarm, Cortex will announce the direction of a collision threat, such as "collision alert, starboard bow." Instead of an ambiguous beep that other AIS systems provide, Cortex tells users what the alert is for and the direction of the threat.
Check boat status, receive alerts and control devices with Cortex remote monitoring access using Cortex handsets (sold separately) or Cortex smartphone apps. Directly connect up to 5 external sensors to your system for added monitoring capability.
Subscribe to a premium Cortex Monitor plan to receive alerts, see real-time information about your boat and remotely control devices such as air conditioning, lighting, refrigeration or ice makers using the Cortex Monitor app on your compatible smartphone.
While you’re on your boat, the Cortex Onboard app can serve as your primary interface with your Cortex M1 hub, allowing you to monitor boat stats, receive alerts, view instrument data and display AIS screens on your compatible smart device.
Broadcast built-in heading via AIS transmissions to other vessels so they can more accurately track their closest point of approach and alter course to avoid you.
Cortex can receive and broadcast information over NMEA 0183 and NMEA 2000 networks, making it compatible with the majority of modern chartplotters and multi-function displays.
