What Is JRC JHS-183 AIS?

The JRC JHS-183 is a SOLAS-compliant AIS Class-A Transponder designed to automatically transmit and receive vessel information.

The system exchanges real-time data such as:

• Vessel Name
• MMSI Number
• IMO Number
• Call Sign
• Position
• Course Over Ground (COG)
• Speed Over Ground (SOG)
• Heading
• Navigation Status
• Destination Information

This information is shared with nearby vessels and Vessel Traffic Service (VTS) stations.

AIS significantly improves situational awareness and maritime safety.
