11 HOW DOES IT WORK?
The AIS SART is a Search And Rescue Transponder/Transmitter, designed
for survivor location during search and rescue operations. From 1st of January
2010, AIS SART was adopted into the GMDSS (Global Maritime Distress
Safety System, Figure 10) regulations as an alternative to the traditional SART
equipment, RADAR SART.
AIS SART provides a greater level of identification and a GNSS based
position during search and rescue operation period then can be provided by a
RADAR SART. The AIS SART transmitting frequency (161.975MHz &
162.025MHz) is fully interoperable with the other uses of the maritime AIS
system. AIS SART combines two antennas, GNSS (GPS) and VHF, and
transmits the latitude and longitude, message 1 and message 14 to other AIS
station.
