Information

The Simrad SA70 SART is a 9GHz Search and Rescue Radar Transponder designed for use in search and rescue operations and gives the location of the distress on an X-band radar display. When the SART is interrogated (hit) by a radar signal, it will immediately start to transmit and be detected on the radar screens of nearby vessels.

Features:

  • Equipped with an LED and a built in buzzer to indicate operation for peace of mind
  • Non-hazardous battery which can be replaced on board: No transport restrictions
  • Easy to release and activate in an emergency situation: Easy to operate under stress/in freezing conditions
  • Light weight and compact design: One of the smallest on the market
  • Mandatory carriage equipment for all ships of 300 gross tonnage and upwards
  • IMO/SOLAS/GMDSS compliant
  • IMO/MED/FCC approved

Simrad SA70 is emergency equipment consisting of: SA70 SART radar transponder and Mounting rope for life rafts / life boats. The 9 GHz radar transponder type SIMRAD SA70 SART is developed by Navico to meet the rules and regulations for use on vessels and life rafts in the maritime service. SIMRAD SA70 SART meets the specifications for 9 GHz radar transponders for use in search and rescue operations at sea.

The operating range of the SIMRAD SA70 SART is up to 30 nautical miles, depending on the height of the electronic unit and the radar height of the search and rescue unit (sea or airborne). With a radar height of 20m and the SIMRAD SA70 SART placed at 1m above sea level, the range will be up to 10 nautical miles. SIMRAD SA70 SART is buoyant, however to obtain maximum performance the transponder should be placed in a vertical position and as high up as possible in order to achieve maximum coverage. Several mounting brackets and mounting aids are available to ensure correct mounting and use of the radar transponder.


The purpose of the SIMRAD SA70 SART is to perform a secondary alarm when search and rescue units are searching for a life raft / lifeboat in distress. The SIMRAD SA70 SART will help the units to pinpoint exactly where the distressed boat is located in a larger area. This is done with the help of the radar on the searching ship or helicopter.

The SA70 AIS-SART is developed by Simrad to meet the rules and regulations for use on vessels and life rafts in the maritime service. SA70 AIS-SART meets the specifications for use in search and rescue operations at sea. The operating range of the SA70 AIS-SART is 7 -10 nautical miles from vessel AIS Class-A, and more than 40 nautical miles from an airborne AIS receiver. 

This will be received by other AIS systems within the range. The batteries of the SA70 AIS-SART will last at least 96 hours when activated.
The SIMRAD SA70 SART should be activated immediately after activation of the EPIRB or by instruction from the rescue control centre
