EasyRescue AIS SART - IMO/SOLAS

EasyRescue AIS SART – Sea rescue transmitter
The EasyRescue AIS SART is a portable emergency transmitter that uses AIS (Automatic Identification System) technology to quickly and accurately locate a drowning person. Once the transmitter is activated, it determines its position based on GPS and sends out a distress signal via AIS within 30 to 120 seconds.

How does it work?

• After activation, the GPS position is determined.
  
• Then AIS distress messages are sent: 8 messages within the first 16 seconds of every minute.
  
• This protocol ensures maximum visibility (signal falls on a wave crest).
  
• Signals are transmitted on AIS channels 87 & 88 (161.975 MHz and 162.025 MHz).

DSC Distress Calls – Direct Communication with Nearby Vessels
In addition to AIS, the EasyRescue Pro and Pro3 also have a DSC class D controller (Digital Selective Calling). This system sends a digital distress call to the mother ship and up to 7 other pre-set ships via the marine radio. As soon as the device is activated, it sends an individual DSC call to these ships within 5 seconds, including GPS position. If no response is received, the following automatically follows:

• After ±5 seconds: first call directly to mother ship(s) to raise the alarm on board.
• After ±1 minute: second call with current GPS position
  
• After 5 minutes: third call
  
• After 10 minutes: an “All Ships Call”, which alerts all ships in the area with DSC
  
• As soon as a ship acknowledges the distress call, the EasyRescue indicates this by flashing a light and beeping. After that, only the DSC part stops transmitting; the AIS distress transmission remains active as long as the device is switched on.

Key Features

• Broadcasting time: Minimum 96 hours at -20°C, up to 6–8 days at normal temperatures.
  
• Also works in busy AIS areas (such as Rotterdam), thanks to the SOTDMA protocol (class A, guaranteed signal priority).
  
• Floating and waterproof (IP68) up to 20 meters depth.
  
• Equipped with bright LED flash for visibility in the dark.
  
• Compact and lightweight design, with self-erecting antenna.
  
• No permit required, but SOLAS/IMO certified.

Usage and activation

• Manual or automatic, depending on the model.
  
• Can be easily attached to or in a life jacket.
  
• Some models activate upon contact with water (after 2 seconds of immersion).
  
• An activation button with break protection prevents accidental use.

Visibility & Compatibility

• Visible as “AIS SART Active” on any AIS compatible chartplotter or PC.
  
• Recognized by professional rescue services and commercial shipping worldwide.
  
• Received messages contain GPS position and distress signal.
