It's not. VTS, Vessel Traffic Services, is a whole different, much older,
system that uses control operators like FAA flight controllers for crowded
waterways watching shore-based radar and other navaids to safely separate
traffic, just like they do in the air. This radio is a VHF marine radio
with a VTS transponder built into it.
