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.
