Product Categories - Personal Locator Beacons - sMRT SHIELD


A MEOSAR & Return Link Service (RLS) capable PLB, with multi-mode high-definition positioning capability, powered by the European Galileo satellite system. 

MRT, in conjunction with the European GNSS Agency (GSA), has developed a MEOSAR compatible PLB that utilises the significant improvements made to the COSPAS-SARSAT system by the integration of the Galileio SAR service.

Benefits of choosing the sMRT Shield

  •  Global coverage with near real time detection and location
  •  Multi-mode locating systems provide SAR assets with highly accurate position information
  •  RLS Function provides user with the comfort of knowing their distress message has been received
  •  Multi-constellation positioning support means higher accuracy and faster time to first position fix
  •  Rugged construction ensures the PLB is suitable for use in the toughest maritime and ‘outback’ environments
  •  Suitable for integration with a wide range of commercially available lifejackets

What is MEOSAR? MEOSAR is the next generation in global distress alerting and location and is available now via the European Galileo satellite system. Search and rescue transponders onboard the positioning satellites relay distress messages to ground stations, providing near real time alerting and locating. 

What is the RLS? On receipt of a distress message SAR  authorities can send the PLB a unique message via the MEOSAR satellites that confirms that the distress has been received. MRT’s PLB features a dedicated indicator that informs the user that their distress message has been received and that help is on the way.
