What Is This Equipment?

The JOTRON AIS TR-8000 is a Class A AIS transponder that automatically transmits and receives vessel information through dedicated maritime VHF frequencies.

The system broadcasts:

• Vessel Name
• MMSI Number
• Call Sign
• Position
• Speed Over Ground (SOG)
• Course Over Ground (COG)
• Heading
• Navigation Status
• Destination
• Estimated Time of Arrival (ETA)

Nearby vessels and shore-based traffic monitoring centers receive this information in real time, significantly reducing the risk of collisions and navigational misunderstandings.
