search and rescue
The VDL 6000 AIS Airborne transponder is developed for aircraft installation for use in Search and Rescue (SAR) and coastal surveillance missions and greatly enhances surveillance of large areas. The localization and identification of all AIS equipped vessels supports increased national security, environmental protection, and the possibility of rescuing vessels in distress.
The SOTDMA technology is used in the AIS transponder which broadcasts and receives information about all AIS equipped vessels within VHF coverage.The information received is easily plotted on an electronic charting display system. This gives a surveillance capability that was not possible prior to AIS.
