Extending VTS Beyond the Limits of Coastal AIS

Posted by Peggy Browning on Aug 28, 2012 3:24:00 PM

As VTS or (Vessel Traffic Service) relies on traffic knowledge gained through surveillance techniques, up to now it has operated only in coverage of Port or Coastal AIS and Radar.  Previously, the lack of surveillance techniques was an obstacle to extend VTS coverage into remote coastal areas and further offshore.  By extending VTS, safety of navigation and the maritime environment will benefit from proactive measures to mitigate convergence and bottlenecks as well as better spatial planning for marine traffic.

Saving Lives with AIS SART Devices

Posted by Peggy Browning on May 2, 2012 3:14:00 PM

The US FCC has recently approved transmissions by AIS SART devices.  These devices were originally designed for SOLAS class ships as an alternative to radar SARTs for carriage on life boats, but the efficiency of design has encouraged applications down to man-over-board devices.   I started to question how this new large population of AIS devices could best be tracked.
